RITTAL reports it 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).The company says 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 as well as a monitoring signal can be much simpler to incorporate in an EC motor than on the AC motor equivalent.
Rittal says its 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.
