Product Overview
The ICM325A Universal Single Phase Head Pressure Control is a great option if you are running your AC system or refrigeration in cold temperatures. Often, head pressure drops when temps fall, but you still need to run your equipment, specifically for server rooms, event spaces and grocery stores. In these and other scenarios, head pressure control is necessary. If the head pressure gets too low, your system will not operate properly, causing serious damage to your equipment. It can cause evaporator freeze-ups, hydraulic lock-ups, compressor burn out and fan cycling among other things. The ICM325A low ambient head pressure control ensures the condenser fan runs at an optimal speed for maximum efficiency. If the condenser temperature gets too cold or the system pressure gets too low, the ICM325A lowers the fan speed vs turning off the fan completely.
The ICM325A also offers users the ability to adjust the parameters from their phone with NFC technology and the ICM Omni App.
Standard features include:
- Operates as temperature or pressure sensitive motor fan speed control
- Helps prevent evaporator freeze-ups, low pressure cut-outs and liquid-slugged compressors in low ambient conditions
