RITTAL says a new fan speed control sensor for its TopTherm fan-and-filter units is now available. The company says this handy and compact device, which is compatible with the larger models in the range of electronically commutated (EC) TopTherm fan-and-filter units, automatically adjusts the fan speed in response to changes in temperature inside the enclosure.

Providing a simple and cost effective solution to the problem of fan-and-filter units running continuously, even when not required as the panel temperature is already at an acceptable level, the sensor will help to reduce energy consumption and consequently, running costs.

With a fixed setpoint of 35 °C, the device can provide continuous control with fan speeds varying linearly between 10 % at 20 °C and 100 % at 35 °C. No additional power supply is required as the sensor takes a 10 V DC feed from the fan-and-filter unit itself.
