water source heat pump system


With Smart Dehumidification, once the space temperature is satisfied, the humidistat signal diverts the high temperature refrigerant gas to the hot gas reheat coil located downstream of the cooling coil. The conditioned and reheated air prevents over cooling of the space, maximizes moisture removal for improved indoor comfort, and is an excellent solution for applications where maintaining low humidity in a space is crucial.

Waterside Economizer


Waterside economizers help to reduce energy consumption by using cold loop water temperature to condition a space without energizing mechanical cooling. Buildings will benefit from the waterside economizer when loop temperatures are cool enough to provide air conditioning to the space.

HVAC Compressors


High efficiency rotary (sizes 007-019) and scroll (sizes 024-070) compressors are designed to optimize heat pump duty and performance. Additionally, horizontal GDH model (sizes 024-070) are available with two-stage scroll compressors for increased operational energy savings, while providing excellent part-load performance and improved humidity control.

Compact EC Motors for Geothermal Heat Pump


With optional electronically commutated (EC) fan motors and 4-position fan speed control, the SmartSource Compact water source heat pump delivers high efficiencies to ensure premium performance.
