The Envision Series NDW is designed to meet the high-volume water demands of today’s larger luxury homes and available with our industry-leading 3-day lead time. NDW units provide high-capacity heating and cooling performance but still deliver the features homeowners have come to expect from our Envision line. Two high efficiency, single speed scroll compressors keep operating costs low for pool/spa heating, radiant floor, snowmelt, aquaculture, and process water installations. Brazed plate heat exchangers provide efficiency and allow for a compact unit. As always, all Envision units use R-410A refrigerant. The Envision NDW also features Aurora Advanced Controls that offers two-way communication between components and allows for accurate energy monitoring. The HydroZone control panel utilizes intuitive menu-driven software and a large backlit display with easy setup configurations and lead/lag pump control for installers. Note: A secondary heat exchanger is needed for domestic hot water and pool/spa heating.
