Head pressure controls are RoHS compliant
An
ICM Controls product story
Edited by the Engineeringtalk editorial team
Nov 28, 2007
New models all feature integral heat-pump bypass circuitry, an adjustable hard-start, a low-speed cutoff and a high-temperature bypass.
ICM Controls has a new line of lead-free RoHS-compliant head pressure controls.
By acheiving RoHS compliance, the ICM325, 326 and 327HN head pressure controls align with a global trend that ensures stricter, environmentally sound standards are maintained by manufacturers.
ICM's head pressure controls operate as temperature-sensitive, motor fan speed controls, regulating head pressure by varying the amount of airflow through the condenser, and helping to prevent evaporator freeze-ups, liquid-slugged compressors, low-pressure cutouts, and overshoots common with on/off and pressure-switch controls.
They are ideal for use in low-ambient conditions common to supermarkets and frozen food storage, computer rooms and cooling tower fans, and many other temperature/humidity-sensitive environments.
Complementing ICM's existing line of head pressure devices, these new lead-free controls are designed with the same reliable circuitry that has earned ICM its industry-wide reputation for excellence.
ICM's head pressure controls are superior in that they run the motor fan consistently at a lower speed, rather than cycling it on or off; the controls continuously make any necessary temperature adjustments throughout, helping to eliminate inconsistent cooling and system wear and tear.
The new ICM325, 326 and 327HN models all feature integral heat-pump bypass circuitry, an adjustable hard-start, a low-speed cutoff, and a high-temperature bypass.
The ICM326 and 327HN additionally feature an integral transformer for simplified installation, cost reduction, and direct setup from the voltage line.
Each provides solid state 10A load carrying capability and can control up to three refrigerant circuits.
