Rittal TopTherm EC fan and filter units

Rittal TopTherm EC fan and filter units Rittal's range of TopTherm fan and filter units has been extended with electronically commutated (EC) variants now available in all but the smallest unit.

With a combination of fan and dust filters and a particularly economical means of dissipating heat loads from enclosures using ambient air, Rittal's EC fan-and-filter units employ the same diagonal fan technology as the standard version. Improved performance against static pressure offers advanced energy efficiency and a more constant air throughput to effectively minimise the occurrence of hot spots in the enclosure.

By using EC motors, an innovation that utilises DC (direct current) motors, which are more energy efficient than the conventional AC (alternating current) shaded-pole equivalent, Rittal's new TopTherm series of fan-and-filter units offer energy savings in excess of 60 percent over previous models and also provide intelligent control and fan status monitoring for larger units.

Infinitely variable speed control enhances a means of conserving energy further by operating the fan at a speed determined by the demand for cooling. A programmable logic controller (PLC) may be used to control the fan motor, via a 0-10V DC or pulse width modulated (PWM) signal.

A tacho-signal output allows direct monitoring of the fan speed and a malfunction or failure is signalled immediately for action, minimising the risk of component failure in the enclosure and reducing system downtime.
