NORDIC® DXTF-Series Triple Function Two-Stage R410a Model Sizes 45-65

(3-5 Ton)

Direct Expansion Triple Function Heat Pumps

UNIT DESCRIPTION
The DXTF-Series unit is a high efficiency two stage direct expansion triple function heat pump with R410a refrigerant. It extracts and rejects heat from the earth via direct contact with copper loops, eliminating the need for a secondary heat exchanger and associated components. The DXTF unit can provide air heating, air cooling, and hydronic heating. Direct expansion units require less “loop” per ton and are more efficient than conventional ground loop systems. The reduced thermal resistance between the earth and the refrigerant circuit provides better heat transfer, resulting in a higher suction pressure and increased output. An electrically commutated (ECM) fan with several speed options is standard. The motor has a soft start function for improved efficiency and reduced wear. The unit has several key features that are described in the specifications document for the particular heat pump. Please get in touch to request DXTF product specifications.
