The NORDIC® (R)-Series active cooling full package units are similar in appearance to the (O) series however they offer mechanical cooling (active cooling) and are specifically suited to either well water or geothermal ground loops. Active cooling is required for a geothermal ground loop application due to the high fluid temperatures which may be encountered during summer operation. (R) series pumps can provide more cooling than (O) style units in the 4 and 5 hp range. Available in 3, 4, 5 and 5.75 HP versions. Domestic hot water option provides hot water in both the heating and cooling modes.

Options Available:

	Domestic hot water desuperheater package.
	Units feature Turbotec® coaxial water heat exchangers.
	Cupro-nickel heat exchangers available.
	Taco® slow closing water valve on open loop units.
	Filter rack is removable for access through a 28" door opening.
	Completely insulated water lines, accumulator and heat exchanger
	208 and 575v - 3 phase systems available.
	10 year extended warranty available.

(R) style units feature an over sized evaporator (Ex. a 3HP heat pump has 5HP Evaporator and a 5HP a 7.5HP evaporator) so that they can achieve very high COP's even when operated on ground loops with EWT's as low as 25°F.
