Overview

Geothermal Efficiency with Added Value

Add water-source heat pump energy efficiency to the durability and reliability of Withair’s large units for greater building-wide comfort. In capacities up to 40 tons, Large Water Source Heat Pumps offer HVAC solutions for a variety of commercial applications including: Office buildings, Schools, Hotels, Apartments, condos, etc.
Optimize Performance with Connected Controls

Operation with smart microprocessor controls includes an optional Modbus Communications Interface or BACnet® Communications Interface to communicate directly to the Building Automation System (BAS) through an open protocol.
Customize WSHP to address the demands of your commercial project

We continues to provide the highest standards in quality and reliability, comfort, ease of service, and the performance. Choose from many factory-installed options to customize the system. We offer a color touchscreen human interface panel that enables more intuitive commissioning, troubleshooting and preventative maintenance, with additional benefits for greater application flexibility.

Customers demand products that provide exceptional reliability, meet stringent performance requirements, and are competitively priced. our Water Source Heat Pump features cutting edge technologies: reliable compressors, smart controls, computer-aided run testing. So whether you’re the contractor, the engineer or the owner, you can be certain our products are built to meet your needs.
Choose a water-source configuration that best meets your efficiency goals

Withair’s Large Water Source Heat Pumps can be configured for geothermal, boiler/cooler or hybrid applications, in closed or open loops with ground-source or surface water. And because units can be installed in rooftop, the entire system is customizable, connectable, easy to install and service.
Optional Waterside Economizer System

If the water-source system design contains an economizing coil option, the moderate temperature loop water circulated through a core water source system can provide an inexpensive means to satisfy room comfort without operating the water source heat pump's compressor.

During economizer mode, fluid enters the unit, and passes by a water temperature sensing bulb. This temperature sensing bulb determines whether the two position, three-way valve will direct the water through the waterside economizing coil, and to the heat pump condenser, or through the condenser only. If the water temperature is 55℉(12.8℃) or less, fluid will flow into the economizing coil, while simultaneously halting mechanical operation of the compressor. Mechanical cooling will continue on a call for second stage from the thermostat.
