The Envision®2 Series NXW Reversible Chiller from WaterFurnace International, Inc. has been updated with new features. These include HydroLink Aurora controls and a 10″ color touch screen display.
The new communicating controls combine field-proven Aurora compressor management with a HydroLink NiagaraAX-based system-level controller to manage set point, control, staging, and the new touch screen display. The controls also communicate more than 200 points to the BAS network via BACnet, LonWorks, or through the NiagaraAX bus.
Custom-built HydroLink Supervisory controls are also available, with the ability to consolidate all mechanical room chillers and hydronic components under one controller. This turnkey solution provides complete plant room management that helps ensure proper operation with easier servicing.
The Envision2 NXW Reversible Chiller’s new 10″ color touch screen HMI tablet display is factory-installed on the cabinet exterior and provides high-end graphics on system performance and control. Each chiller is equipped with a small Wi-Fi router or hardwire Ethernet connection that offers additional connectivity options to display chiller information without tapping into the BAS network.
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.
