Product Details Supplier Info More products

Rittal has launched the EC Speed Control unit, which is compatible with larger models from the TopTherm EC fan-and-filter unit range (uninstalled air throughputs between 180m³/hr and 900m³/hr).

Fan-and-filter units with electronically commutated (EC) motors for electrical enclosure cooling are already recognised for their lower energy consumption and extended service life. Furthermore, infinite speed control and a monitoring signal are simpler to incorporate in an EC motor than on the AC motor equivalent.

Rittal’s new EC Speed Control supports these benefits and adds a number of others. It can be used to reduce the noise output of EC fan-and-filter units, as well as lower energy consumption through the ability to control the speed of up to four units. Cooling demand — and hence the required fan speed — is determined by comparing the sensed temperature inside the enclosure with the set-point temperature on the device, from +5°C to +55°C.

EC Speed Control is also able to closely monitor the status of the fan. The unit provides a local visual display of the operating status and incorporates an alarm relay for the remote monitoring of over-temperature, fan defect, cable break and sensor failure.
