Ultra NSW Single Hydronic

Versatec Ultra NSW Single Hydronic NSW 1.5 to 6 Ton

Up To 15.5 EER
Up To 4.8 COP

Versatec Ultra Single Hydronic

Perfect for hydronic commercial applications or for domestic hot water.

High Efficiency in a Compact Cabinet

The Versatec Ultra NSW features a single-speed compressor housed in one of the most compact cabinets in the industry, but it also boasts an optimum level of efficiency thanks to oversized heat exchangers.

Domestic Hot Water Heating

The Versatec Ultra NSW 018 and 025 are available with load-side copper vented double wall coaxial heat exchangers that provide domestic hot water heating without the need of a secondary heat exchanger.

Small Cabinet Footprint for any Application

Ideal for installations where space is limited, the Versatec Ultra NSW boasts a compact size and is also stackable (up to three unis high) to allow more capacity installation in smaller spaces.

Aurora Controls for any Application

Our communicating Aurora Controls bring all aspects of the HVAC system into one cohesive module network and provide two-way communication among components. Setup, troubleshooting, and diagnosis are simplified for contractor convenience.

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

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
Factory Quality

All refrigerant brazing is performed in a nitrogen environment.

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.

Reversible

Available in heating only or reversible operation.

Hot Water Generation

Optional hot water generator is available with externally mounted pump and water heater plumbing connector.
