Universal Low Ambient Head Pressure Control ICM-325A

The Universal Low Ambient Head Pressure Control (ICM-325A) is a smart, solid-state solution engineered to maintain optimal system performance in low ambient conditions. Designed for air conditioning and refrigeration systems, this control automatically modulates condenser fan speed to stabilize head pressure when outdoor temperatures drop below normal operating ranges. Compatible with PSC and ECM motors, it operates on 120/240 VAC and features an adjustable pressure set point for precision control. The rugged, weather-resistant design includes built-in surge protection, reliable triac switching, and a compact enclosure ideal for both new installations and retrofits. With the ICM-325A, technicians can count on smooth compressor operation, quieter fan performance, and consistent efficiency year-round—especially in demanding or variable climates.
