Nordic RS Series Water to Air Heat Pumps - Split


The RS-series is a split water source heat pump (with remote indoor air handler) that can heat or chill air in a forced air duct system. Being a split system it provides the ability to locate the compressor unit and air handler in different locations. It also uses its built-in desuperheater to preheat domestic hot water. This unit is available in sizes from 3 to 6 nominal tons, and works on an open water well or closed ground loop.
