Water Source & Geothermal Heat Pumps - Versatec Ultra

0.75 to 6 Tons (13 sizes)

Up to 15.7 EER / 5.1 COP

Provides a higher, mid-tier efficiency option offering a wide range of features and options.

High Efficiency in a Compact Cabinet

The Versatec Ultra 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-up to 15.7 EER and 5.1 COP (ISO/AHRI 13256-1 WLHP). That means replacing those old inefficient water source systems will be simpler than ever.

Reliability is Key

Long component life and reliability is vital in commercial applications. That's why we feature all-aluminum rifled tube-and-fin air coils as well as corrosion-proof composite or stainless steel drain pans to provide the building a long lifetime of reliable system operation.

Hot Gas Reheat for Humidity Control

The hot gas reheat option removes moisture from the air without over-cooling the space. The result is consistent, dehumidified conditioning for maximum occupant comfort. Hot gas bypass is also an option and is available together with reheat or standalone.

Unique Fan Benefits

WaterFurnace's dedicated 460-volt 5-Speed ECM doesn't require the use of a neutral, which reduces labor costs in retrofit applications and is unique to the industry. The Versatec Ultra features variable speed fan options as well as standard PSC.

Aurora Controls for any Application

Our communicating Aurora Controls include a Base option that allows for 8-wire 24-volt or 4-wire communicating thermostat use while our Aurora UPC DDC option allows for building automation using N2, BACnet, or LonWorks.

Flexible Factory-Installed Options

We offer internally mounted secondary drain connections as well as internal water valve and/or flow regulators for variable speed pumping systems. This option saves on installation and operating costs providing you with all you need in the system before you even receive it.

Other Key Features

Water Side Economizer

Factory-installed water side economizer for free cooling when building conditions are correct.

Coated Coil

AlumiSeal coated aluminum air coil option is available for even more protection and to meet code requirements.

Phase Guard

A factory-mounted phase guard device is available to protect the compressor against loss of phase.

Power Disconnect

An internally mounted non-fused power dial disconnect is also an option to avoid scheduling problems with the electrical contractor.


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.

Painted Cabinet

A painted cabinet option is available for the Versatec Ultra providing durable powder-coat protection and an appliance-like finish.

Multi-Density Compressor Blanket & Sound Kit

The super quiet sound package is standard while an optional Sound Kit is available for units installed in areas that need even more noise dampening.
