Description
The Bard HVAC CMA-39 Low Ambient Control is a precision-engineered accessory designed to keep air conditioning and heat pump systems operating reliably in cold outdoor conditions. Without low ambient protection, standard cooling equipment can experience refrigerant pressure drops, compressor damage, and system lockout during cool or cold weather operation. The CMA-39 addresses these challenges by modulating condenser fan operation to maintain proper head pressure, ensuring consistent and safe system performance even when outdoor temperatures fall below normal operating ranges.
Built to Bard HVAC’s exacting standards, the CMA-39 is an ideal replacement or upgrade component for commercial and light commercial packaged HVAC systems where year-round cooling is required — such as server rooms, telecommunications enclosures, process cooling applications, and climate-sensitive commercial spaces.
