![ICM Controls ICM325A Low Ambient Head Pressure — New England Supply House spec card [NESH-SPEC-CARD-V2]](http://newenglandsupplyhouse.com/cdn/shop/files/spec-9032831467742.png?v=1782844507&width=1445)
ICM325A is a Low Ambient Head Pressure Control designed to optimize refrigerant head pressure in cold climates. This retrofit-friendly control replaces ICM325H and related variants, including ICM325HNV, ICM325HNC-LF, ICM325HC, ICM325HNC, ICM326HN, ICM327HN, and ICM333, giving you a single, streamlined solution for multiple systems.
Engineered for reliable operation in harsh environments, the ICM325A maintains stable head pressure, protects compressors from surge, and reduces cycling at low ambient temperatures. Its compatible design supports smoother startup, improved energy efficiency, and extended equipment life without sacrificing performance.
Designed for HVAC and refrigeration professionals, this control offers flexible installation and consistent control across a range of ICM models.
- Replaces numerous legacy models including ICM325H, ICM325HNV, ICM325HNC-LF, ICM325HC, ICM325HNC, ICM326HN, ICM327HN, and ICM333
- Low ambient head pressure regulation to prevent compressor overload
- Retrofit-friendly for quicker installations
- Energy-efficient operation with reduced cycling
- Durable construction for long service life
