Geothermal heat pump

20 Sep 2014
WaterFurnace International, Inc. has introduced the new Envision2 NXW Chiller, providing water heating and water cooling for a wide range of applications. Available in 10- to 50-ton capacities, the NXW will fit through most doors and features external fork truck lifting points for easy installation. Designed to perform to the highest standards in the industry, the NXW can be used as a water source heat pump or as a geothermal heat pump.
 
Equipped with an improved control box that provides clean wiring and easy accessibility, NXW includes an emergency shutdown button and a user interface to aid in setup and diagnostics. Additional features include: 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 optional temperature set-point control software to control leaving load temperature. The Envision2 NXW Chiller is controlled using FX10 microprocessor controls, enabling an easy connection to a Building Automation System with N2 Open, BACnet, or LonWorks protocols.
