HydroHeat manufactures ground and water source heat pumps. The TwinLine geothermal heat pump provides air conditioning and space heating for large commercial applications. It incorporates the advanced technology of GSHP of the HydroHeat Extended Range Series. This heat pump with its two-stage operation provides heating and cooling and saves maximum energy.
The TwinLine geothermal heat pump operates efficiently on entering water temperature of 26 degrees Fahrenheit in heating mode and 95 degrees Fahrenheit in cooling mode. This high efficiency makes the HydroHeat TwinLine heat pump suitable for boiler and cooler tower or geothermal applications. The two-stage operation is performed by the two hermetically sealed compressors along with refrigerant circuits. This pump is available in a dual circuit design together with a staged random compressor starting.
The cabinet of the TwinLine geothermal heat pump is constructed with an aluminized steel to resist against rust. This heat pump from HydroHeat is insulated with a high density insulation to provide an ultra-quiet operation. It is also equipped with a heat exchanger, which is foam-insulated and a belt-driven variable pitch pully. There are multiple access panels for easy inspection and service. The TwinLine heat pump is offered in 8 and 10 ton sizes and in two models for space heating and space cooling.
