Rittal offers a more energy efficient means of ventilating enclosures by supplying electronically commutated (EC) versions of the successful TopTherm fan-and-filter unit, in all but the very smallest size.
Using the same diagonal fan technology as the standard variant, Rittal’s TopTherm EC fan-and-filter unit provides improved performance against static pressure, offering a more constant air throughput and energy savings in excess of 60 percent over previous models. Compliance with ongoing energy efficiency guidelines can be met and exceeded by using EC motors. Intelligent control and fan status monitoring is available for larger units.
Direct monitoring of fan speed is via a tacho-signal output with a malfunction or failure signal, prompting immediately action, minimising the risk of component failure in the enclosure.
Infinitely variable speed control offers a means of conserving energy further by operating the fan at a speed determined by the demand for cooling.
