In the heating mode (Figure 1), hot refrigerant flows through the air coil. The heat pump supplies warm air to the conditioned space. The heat added to the room air is removed from the water flowing through the coil, plus rejected compressor heat.
In the cooling mode (Figure 2), cold refrigerant flows through the air coil. The heat pump supplies cool air to the conditioned space. The heat removed from the room air is transferred to the water flowing through the water coil.
Compact cabinet design with quick access for ease of service. Horizontal units can be serviced through the unit bottom to virtually eliminate removing ceiling mounted units for service.
Oversized blower for quiet operation. A PSC fan motor is standard for economical operation with an optional constant torque multi-speed EC motor, with soft start and serviceable from one side.
Internally trapped (vertical models), stainless steel drain pan for years of trouble-free service.
Compact and efficient compressors, with double isolation for quiet operation.
Thermostatic expansion valve maintains maximum capacity under a wide range of operating conditions.
Heavy duty coaxial heat exchanger for reliability. Enhanced internal surface treatment for increased efficiency (CuNi available).
Water connections are securely mounted flush to the cabinet to eliminate the need for a backup wrench.
Each unit ships with solid state microprocessor controls with safeties built-in for reliable protection.
Satin galvanized and acoustically insulated cabinet for years of quiet operation.
Unit capable of operation on a closed loop or a water well installation.
Hot Gas Reheat is used for humidity control and for occupant comfort. The integrated reheat coil is used to add sensible heat to the air stream to maintain the temperature setpoint and occupant comfort.
We engineer and manufacture vertical stack fan coil units and water source heat pumps for a wide range of applications.
