Available in 10 ton to 50 ton capacities using R-410A refrigerant, the Envision2 NXW reversible chiller provides water heating and cooling for a wide range of applications, including pools, commercial aquariums, radiant floor heating, ice melt, chilled water application, and industrial process water. The unit also delivers precisely heated or cooled water for fan coils or other applications. Its compact design fits through most doors and features external fork truck lifting points for easy installation.

The NXW is equipped with a control box that offers clean wiring, easy accessibility, and an emergency shutdown button. Additional features of the Envision2 NXW reversible chiller include forklift cutouts in the base of the frame accessible without removing an access panel; Class J fuses for short circuit current rating (SCCR) up to 100 kA; temperature sensor wells for accurate water temperature sensing; copper-brazed, oversized stainless steel heat exchangers for high efficiency and low water-side pressure drop; and bidirectional liquid line filter driers to maximize system cleanliness. Options include temperature set point control software to control leaving load temperature and factory-installed pressure gauges.
