Demand based cooling and monitoring… from a fan-and-filter unit!

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

Fan-and-filter units with electronically commutated (EC) motors for electrical enclosure cooling are already recognized for their lower energy consumption and extended service life.  Furthermore, infinite speed control as well as a monitoring signal are much 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 noise output of EC fan-and-filter units, as well as lower energy consumption still further 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.

The Rittal 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.

This exciting and innovative new product sees the humble fan-and-filter unit come of age, providing demand-based cooling,
greater temperature stability inside the enclosure, and performance monitoring, alerting users to any problems with their cooling system.

It transforms the fan-and-filter unit into a smart solution perfectly suited to the modern technical era.
