NDW Dual Hydronic

Envision NDW Dual Hydronic NDW 8 to 15 Ton

Up To 15.8 EER
Up To 4.6 COP

Envision Hydronic

Provides high volume hot water output for larger commercial hydronic applications.

Heat Exchangers
High Efficiency Operation

The Envision NDW features dual single-speed compressors housed in a compact cabinet and boasts an optimum level of efficiency thanks to oversized heat exchangers.

Compact Cabinet Footprint for Application Flexibility

Ideal for installations where space is limited, the Envision NDW boasts a compact size and features optional top or back mounted water lines as well as a field switchable control box for flexible installation in any water-to-water application.

Integrated DDC Controls

An FX10 DDC controller provides features unique to WLHP controls. The DDC controls provide service diagnostic faults an avenue to be communicated through the DDC directly to the building automation system. Detailed and accurate information is available without removing an access panel.

Quiet Operation

Efficient compressors are featured that operate quietly while discharge line mufflers help quiet compressor discharge gas pulsations. Heavy-gauge steel cabinets are insulated with acoustic type glass fiber to minimize operation noise.

Maintenance and Service Advantages
Maintenance and Service Advantages

A field switchable control box, removable compressor access panels, and quick attach wiring harnesses combine to make installation, maintenance, and service a breeze.

Other Key Features
IntelliStart

The optional IntelliStart soft starter will reduce the normal start current (LRA) by up to 60% to reduce light flicker, start-up noise, and to extend the compressor life.

Thermostatic Expansion Valve

A balanced port bi-directional thermostatic expansion valve is utilized for precise refrigerant metering.

Brazed Plate Heat Exchanger

Large oversized stainless steel interlaced copper-brazed plate water-to-refrigerant heat exchangers provide unparalleled efficiency.

Factory Quality

All refrigerant brazing is performed in a nitrogen environment.
