  • Enclosures - Getting it right first time

    The cost of getting a product to market is on the increase and the last thing you need is for machinery and plant to break down at the critical moment. Alan Lawson from PSJ Fabrications explains the benefits of specifying a bespoke motor control centre, and why it pays to invest in the right solution for you

    Motor control centres (MCCs) have been in use since 1950 when they were first introduced in the UK by the automobile manufacturing industry. They are now far more common and are used in many industrial and commercial applications to accommodate a wide variety of different devices required in modern facilities.

    The basic role of a motor control centre is to protect valuable electrical components and it therefore doesn’t make sense to save a few pounds by purchasing an inferior product to protect high value systems. A substandard MCC could bring with it all kinds of problems including leaks and damage to equipment, all of which will result in downtime and thus specification should not be taken for granted.

    In short, the same level of time and investment should go into choosing the right motor control centre and this should reflect the time and money spent on developing the system which it contains and the machinery which it protects.

    Make your choice
    There are a few key items which should make up your specification for a motor control centre, including ampacity (the maximum amount of current that the main horizontal bus can accommodate without overheating), bussing material and feeder cables – all of which could mean the difference between a long and reliable service life or an early, abrupt failure.
    But possibly one of the most important things to consider when specifying your MCC is ensuring it is suitable for the environment in which it will operate.

    In an ideal world the motor control centre would be located in a separate air conditioned room, but with space at a premium an MCC will often be found on the factory floor next to the machinery which is being controlled. This brings with it the inevitable problem of how to protect the contents from dusty and corrosive processes which is why it is imperative to ensure the MCC which you specify is suitable for the area in which it is located.

    Benefits of bespoke
    There are a number of issues which you need to consider when specifying a motor control centre, the first of which is the size. How many times have you heard stories from people who have bought new machinery for the factory floor and then discovered that it doesn’t quite fit into the space which had been set aside for it? The same happens with an MCC, which is where a bespoke solution becomes the right option.

    By specifying a bespoke solution you can work with the manufacturer to ensure it perfectly fits the space which you have available – which is particularly useful if you are tight for space and need to pack as much into it as possible.

    The other main benefit of being able to specify the exact size is versatility, because it enables you to take into account the requirements of your factory or commercial process, and then specify exactly what you need within your MCC without having to work around the ‘standard’ option the manufacturer wants you to have because that is all that they supply. A good example of this would be the option to have fixed or withdrawable starters, distribution and control aspects or if the MCC needs to be specifically designed for harsh environments.
    This brings me onto the material in which the MCC is manufactured, because the material on the outside is just as important as the contents of the MCC.

    We manufacture all of our cubicles from 2mm and 3mm stainless steel, with a main frame that is fully welded for strength and rigidity and doors, shelves and mounting plates bolted in position.

    Stainless steel has typically been used in the food manufacturing industry, but has grown in popularity for external applications over the years because of its ability to provide the same benefits as mild steel but with a greater longevity in harsh or aggressive environments. It is also rust resistant and has its own natural finish so requires no further treatment.

    The benefits of a bespoke solution however mean that if you do require a specific finish then that option is available. We regular receive requests to match specific colours so that the MCC blends in with its environment and we then carry out a process which includes degreasing and rubbing down to remove all traces of dirt and rust, before priming and applying the paint at a depth of 50 microns to ensure colour longevity in even the harshest conditions.

    The right rating
    Getting the right IP rating is also a very important issue when specifying a motor control centre, particularly when it will be located in a harsh environment. IP stands for Ingress Protection and it is a rating that describes the protection from the intrusion of solid and liquid material.

    The letters IP are always followed by 2 numbers, the first refers to intrusion by solids (1-6) and the second refers to intrusion by liquids (1-8). All of our cabinets are protected to IP55 which means that they are protected against the ingress of dust and dirt and low pressure jets of water.

    You will find this rating is suitable for the majority of the environments in which a motor control centre is located and in order to retain the ingress protection all of our doors and covers are press formed for positive alignment.

    Make it future proof
    Without the aid of a crystal ball it is difficult to see what the future will hold and with the needs of every business changing rapidly it is impossible to predict your needs five years from now. But with an MCC having an average shelf life of 25-30 years you need some reassurance that the money you are investing now is well spent and that what you are specifying will match your needs well into the future.

    Future-proofing your MCC is therefore the obvious answer and a bespoke solution allows you to do this. By working closely with the manufacturer it is possible to design a solution which adequately meets the needs which your business has today but at the same time it allows you to build in some space which can be used for future expansion.

    It makes sense
    Generally speaking we all like to be given a choice and when times are tough we are more likely to scrutinise every penny which is being spent to ensure it is being put to good use. I’m not sharing any trade secrets when I say purchasing a new motor control centre is an expensive business but at the same time it is still possible to get value for money if you look carefully at all of your options, before you part with any of your hard earned cash.

    Don’t be tempted to make any quick decisions and do bear in mind the fact that a motor control centre sits at the heart of your business and while a cheaper, off the shelf solution may seem like a good idea, will it still seem like it was the best option when it fails to live up to your expectations 2 years down the line?

    Downtime is costly and we all have enough on our plates at the moment without having to worry about our systems and machinery breaking down at a critical time which is why it makes sense to choose the most appropriate MCC for the job. A typical motor control centre will be in operation for the next 25-30 years and it is vitally important that this period of time is largely trouble free.

    By opting for a bespoke design it is possible to tailor-make a solution which suits your needs now but will also provide space for expansion in the future, thus guaranteeing the longevity which you require and saving you more expense in the future. Reliability is also a key factor, and again, with a bespoke solution you know that it has been built to your exact specification and therefore will provide the control which you require both now and in the future.

    Put simply, a bespoke motor control centre makes sense both now and for the future of your business. It therefore pays to look at all of the options available and ensure that whatever solution you choose is right for you, your budget and your business.

  • Re-tooled enclosures for extreme environmental installations

    The dynamically re-engineered Euronord and Tempo enclosure ranges from Fibox are not only innovatively designed, robustly built as demanded by industry, but are also very affordable.
    In addition to the wide range of standard enclosure products, Fibox can custom manufacture these enclosures based on customer requirements for small, medium and large-scale projects.

    During 2010, the company has invested heavily in rationalising the entire range of EURONORD enclosures and has made the aluminium range available in 22 additional sizes ranging from 50 x 45 x 32 to 600 x 310 x 180.The entire range is now produced using the very latest vacuum die cast technology, which completely eliminates the possibility of air pockets and now features products with perpendicular walls which eliminates draught angles, thus offering an attractive option for enclosures that need to be sequentially mounted.

    The new design also gives extra protection for gaskets in the covers and as well as industry standard internal mounting points. The company's designers have also added extra pods for flexibility. Euronord enclosures are available either painted or unpainted and the company's usual high quality complete customising service is also available.

    The Euronord PC/ABS range has also been completely re-tooled and now offers end users a choice of 18 footprint sizes plus various height options with quick release cover screw options, in addition to standard screw versions. The new range still offers industry standard internal mounting points, but additionally they now feature extra pods for flexibility. The usual Fibox complete customising service is again available.

    Fibox has also announced newly added benefits to the industry preferred, Tempo range.

    In order to deliver a viable option to those ‘less expensive' imports that have appeared on the market, Fibox have added 5 new sizes to the smaller end of the popular Tempo series. These enclosures feature the option of knock outs and free cover retention hinges on all sizes. This range now offers installers a genuinely low cost, high quality (ABS - IP65) range of value for money enclosures for those many projects with increasingly tight budgets.

  • First round diecast enclosures for industrial equipment

    ROLEC has introduced the new ‘aluDISC’ range - the world’s first standard round diecast aluminium enclosures for industrial electronics and electrical equipment.

    This new range has a unique round shape which has been designed to integrate both visually and functionally with industrial applications where everything is round: pipes, tanks, lamps, displays etc.

    Typical applications will include process control equipment, monitoring and detection systems, flow metering and other industrial measuring devices.

    The ‘aluDISC’ enclosures are rated to IP 66 as standard, but can also be specified to IP 67 and IP 69K.

    Manufactured in diecast aluminium and powder painted light grey RAL 7035, the ‘aluDISC’ enclosures have external dimensions are 150 x 139 x 80 mm. Three further industry standard sizes are planned for introduction before the end of 2011.

    The attractive design features clip-in lid cover trims moulded in black POM plastic which hide all of the assembly and mounting screws, thus giving a clean and very modern appearance when assembled.

    ‘aluDISC’ enclosures can be mounted to a wall or machine while still assembled, without the need to remove the lid, thus avoiding any potential damage to the internal components or sealing gasket. The clip-in trims are simply snapped into place after mounting.

    A round recessed area in the lid is designed for mounting membrane keypads, display modules, controls or product labels. A separate model is also available pre-fitted with a transparent hinged cover for extra protection of the controls. The cover is secured by a quarter turn fastener.

    Rather than having a completely round housing, ROLEC designers used the wrist watch as inspiration when designing the ‘aluDISC’. As a result, they included two flat areas either side of the round face for mounting cable glands, connectors and controls.

    Threaded screw bosses are provided inside for mounting PCBs, mounting plates, earth leads and other components. Mounting screws are included in the kit. Prices for the ‘aluDISC’ start at around £60.

    Accessories include unique replacement lid assembly screws which include moulded retaining straps for keeping the lid in situ during servicing or installation.

    ROLEC offers a full customising service on these enclosures with CNC milling, drilling, silk-screen printing, assembly of cable glands and terminals and much more, providing a fully finished housing ready for fitting the components.

  • Enclosures - Designing system enclosures to save energy

    Often you hear people talk of ‘Green IT’ but, love or loathe it, it’s here to stay and proven to be more than just a passing fad, today it is rather an economic necessity. Green IT is not only concerned with saving energy, but involves other factors, such as the use of non-toxic and recyclable components. nevertheless, the key issue remains saving energy, which is unlikely to change. There are many options available for IT managers to save energy, but in reality success can only be achieved through a combination of methods

    The use of power saving server systems, using classic technologies such as APM (Advanced Power Management) and ACPI (Advanced Configuration and Power Interface), has now become an industry standard. There has also been a great deal of progress made in regards to the energy efficiency of CPUs within modern systems, in some cases saving up to 90%. However, the methods and systems that ensure data centre infrastructures save power are far more interesting than the above-mentioned technologies. Uninterruptible power supplies and climate control systems play a central role in green IT as, alongside the servers, the UPS and cooling systems consume the most energy.

    Progress made in semiconductor technology means there are nowadays no problems in building UPS systems without a transformer. A DC booster is used for the transformer-less technology which is a DC/DC converter that converts the voltage behind the rectifier to a significantly higher direct voltage. This increased direct voltage then allows the inverter to create a higher alternating voltage without needing a downstream transformer.

    Transformer-less technology provides several advantages. Firstly, UPS systems without transformers can be built with very compact dimensions. Secondly, the transformer is not exactly a ‘lightweight’ which means systems without one are significantly lighter than conventional systems with one. Furthermore, the noise level of a UPS system without a transformer is significantly less than a comparable system with one. The efficiency over the complete load range is better for the transformer-less technology than for UPS systems with transformer.

    Powerful UPS systems, such as the PMC (Power Modular Concept) from Rittal, can provide efficiency up to 95 % at under full load and up to 94% under partial load or with non-linear loads, CO2 emissions can also reduced by around 20%.

    Battery management systems should also be considered to monitor all the relevant data such as battery voltage, internal resistance, discharge curve and temperature. This data can then be evaluated and used to control the charging process which can increase the lifetime of the battery by up to 30%.

    System integrators and engineers should increasingly think about the enclosure and approaches to thermal management foremost in the design process. This used to be something of an afterthought, which can lead to a poor and ineffective system cooling solution, creating the problem of excessive energy costs for the end user as well as expensive down time, due to premature component failure.

    So much of today’s selection criteria for an optimal enclosure solution centres on thermal performance. Thermal performance, more than any other single element of the design, will form the base line for the design of any enclosure. Depending on the application, size, and external ambient and internal heat load can each have an impact on the design used to solve the system cooling. As equipment is becoming smaller and requires dissipation of larger heat loads, a larger portion of the design effort should be dedicated to optimising the thermal efficiency of the system.

    Fan and filter units are still ideal for dissipating heat loads cost effectively. The pre-requisite is the ambient air must be relatively clean and with a temperature below the desired enclosure internal temperature. Products are also now available with EMC shielding and IP54 protection category as standard and by utilising fine filter mats and hose-proof hoods higher IP ratings can also be achieved. However, in many situations, this method of cooling is not ideal, especially in environments with higher ambient temperatures or where dust or oil particles may be present.

    Air-air heat exchangers use the ambient air to cool the air within the enclosure interior. Based on the counter flow principle, the completely separate airflows are routed through the heat exchanger by powerful fans; separating the internal and external air circuits prevents the ingress of dust into the enclosure. Air-air heat exchangers are best suited where the ambient air temperature is below the required enclosure internal temperature.

    Cooling units maintain the enclosure internal temperature at a constant particular level which is often below the ambient room temperature. Two separate circuits prevent the ingress of dust from penetrating the enclosure. This option is normally available as a wall or roof mounted option and can be individually tailored to suit each particular application.

    Air-water heat exchangers are a relatively low maintenance option to effectively dissipate high heat loads. By using the spatial separation of the heat exchanger and the re-cooling system, the room housing the enclosure is not burdened with the waste heat. In all areas with extreme ambient conditions, enclosure and climate control components are subject to special requirements but for application areas with high ambient temperatures up to 70°C and extreme dust contamination this technology offers an effective solution.

    Recooling systems ensure centralised, efficient cooling using a cooling medium (generally water), to dissipate particularly high heat loads. These units can serve several pieces of equipment simultaneously such as the air-air heat exchangers. If the equipment has different requirements in terms of inlet temperatures or flow rates, multi-circuit systems can be tailored to the respective needs. Units can be provided for either internal or external siting for a vast range of kW cooling capacity.

    Direct cooling packages are best for effectively cooling power electronic components. Heat loads are cleverly dissipated from the enclosure or housing using cold pate technology without compromising the high enclosure protection. Devices such as inverters are physically attached to a cooling plate which is fed by cold water from a re-cooling unit. This method of cooling is not only quiet, but also a thousand times more efficient than heat dissipation via air.

    Liquid cooling packages (LCP), cater for extremely high heat loads typically found in IT or server racks. Liquid cooling, using water as the medium to transfer energy can offer the solution to localised cooling due to its close proximity to the racks. Manufacturer Rittal’s LCP is fitted as an extension to the rack or, in some cases, inside the rack itself so cooling takes place where the heat actually rises – in the server rack itself. LCP needs to be fed with a constant flow of water at a specific temperature to feed the air-water heat exchangers - normally an external IT fluid chiller. However, significant energy savings can be made if free cooling is used. A free cooling unit (FCU) uses the outside ambient air to cool the heated water by means of built in fans and delivery pumps which are integrated into the cooling unit. Free cooling cannot be used in a unrestricted way in every region and only functions when the external air temperature is at least 3k below the allowed inlet temperature of the cold water system (so is ideal for anywhere within the northern hemisphere). Depending on geographical location, up to 50% of the water can be cooled by free cooling, again, offering significant energy savings.

    Today the data centre is not only being scrutinised for up time but is also importantly targeted on its environmental impact. For years silicon chips just burned energy to ensure that the data rates were maximised, now, as a result, the carbon footprint is a significant factor in any data centre design. We know the carbon footprint looks at the effect of the generation of CO2 into the environment but the more CO2 we generate the more the planet needs to absorb, and to maintain that balance is essential.

    Hot aisle cold aisle systems are a common method of delivering cold air to the servers within a data centre. Using a computer room air conditioning system, generally abbreviated to CRAC, the cold air is pushed under the floor. Using vented tiles, statically positioned in front of the server enclosures, allows cold air to escape and then pulled into the server inlet. In essence a CRAC system can be broken down into three elements, an air to water heat exchanger, a fan and a chiller to provide the cold water. The hot air within a data centre is drawn through the heat exchanger by the fan and then the cold air is dispersed under the floor. Therefore, when looking at energy efficiency, there is a need to look at these elements in detail.

    Software calculation programmes, such as Rittal Therm, for the climate control of enclosures, have been developed to eliminate the laborious calculation of climate control requirements. An easy to use interface leads the user to the appropriate and correctly dimensioned cooling solution.

    Whether your requirement is for a new build or upgrade you can tune the energy savings to not only meet your business needs, but also provide a future proofed, energy efficient system. Going green is not a fad; it is ‘good engineering’.
