Envision² NXW Domestic Hot Water

High efficiency dedicated heat recovery operation for domestic hot water. By utilizing a pre-heat strategy for hot water, you can reduce your operating costs by 20%*.

High Efficiencies Through Dedicated Heat Recovery

By utilizing a pre-heat strategy for hot water, you can reduce your operating costs by 20%*. The NXW Domestic Hot Water Chiller can reduce the load on the cooling tower, reduce energy consumption, save money and address the energy side with pre-heat.

Advanced Controls

The HydroLink Aurora controls platform provides numerous factory-installed options to provide better service, diagnostic, and monitoring ability. New features include refrigerant, energy, and performance monitoring all through the HMI or through DDC protocols.

Building Electrification Instead of Fossil Fuels

The NXW Domestic Hot Water doesn't rely on natural gas, which helps the building owner to reduce fossil fuel consumption and their carbon footprint impact on the environment. Heat that is wasted through a cooling tower or ground loop is instead recovered and used for hot water pre-heat.

* Data based on average commercial building in CBECS from the U.S. Energy Information Administration. Actual energy savings may vary.
Storage Tanks

Our storage tanks are UL Certified for electric water heaters and water storage come with factory-installed temperature/pressure relief valves. The tanks are glass-lined with primary and secondary aluminum anode rods which provide maximum protection against corrosion. The brass tamper-resistant drain valve provides durability and longer life than plastic valves.

Serviceability Benefits

Our control panel was designed with the technician in mind to provide convenient, clear wiring with plenty of working space. The panel is split into a left and right side with access to both for ease of service.

Quality Components for Efficient Operation

Oversized true brazed plate heat exchangers offer high efficiency with industry-low waterside pressure drop while dual scroll compressor technology provides consistent reliability and efficiency.

Other Key Features
Factory-Installed Options

A factory-installed pressure/temperature port is externally accessible for improved serviceability while factory-installed high accuracy sensors measure system pressures and temperatures. Factory mounted, internally wired non-fused disconnect is also available.

Noise-Dampening Features

The compressor suction/discharge tubes come with a braided stainless steel vibration absorber to dampen compressor vibration on system piping resulting in quiet operation.

Phase Guard Monitor

Provides phase reversal, phase imbalance, and loss of phase protection.
