Product Overview

—— Product Description ——

Withair® water-source heat pump (WSHP) delivers high-performance heating and cooling with exceptional efficiency: up to 5.0 EER on select systems. Advanced technology makes a Withair® water-source heat pump easy to operate and maintain, resulting in optimal comfort and long-lasting durability. The broad range of products suit a variety of applications: schools, office buildings, health care and rehabilitation facilities, condominiums and retirement facilities and other commercial buildings are just a few of the building types utilizing the energy conscious water-source design of the 0.75 through 38+ tons horizontal and vertical water-source heat pump.

Withair® Water source heat pump systems are among the most efficient,economical and environmentally friendly methods to heat and cool buildings. Withair® has taken these benefits to a new level with horizontal and vertical water source heat pumps. We designed products to give you maximum flexibility to design, install, operate and maintain the ideal water source heat pump system for your building project. And we incorporated non-ozone depleting R-410A refrigerant, which–along with high Energy Efficiency Ratios (EER’s)–helps preserve our environment and precious energy resources.Withair® Water source heat pumps offer you the ability to achieve industry-leading energy efficiency in boiler/tower and geothermal applications.You can benefit from lower energy bills and higher energy rebates.

Withair® is among the original suppliers of water source heat pump systems and has remained at the forefront in expertise and the breadth of our product offering. Known for their compact size, quiet operation and durable with low maintenance requirements and quality construction. WSHPs are available in wide range of capacities and can be combined with electrical heating elements.The units are suitable for cooling tower installations, ground water sources or open water circuits.

Withair® ceiling-horizontal water source heat pumps are typically installed above hallways and other corridors, away from the occupied space for reduced sound and to allow easier service access. each single circuit unit provides heating and cooling to a specific space within the building. Withair® units allow easy access to critical components for maintenance and service access in a ceiling-hung application.

Withair® floor-vertical water source heat pumps are typically installed in closets or small mechanical rooms near the occupied space. each single circuit unit provides cooling and heating for a specific zone within the building. we offers some of the quietest water source heat pump units in the industry, allowing units to be located near the occupied space with minimal acoustic impact.

Withair® continues to enhance the application of Geothermal and other WSHP systems to help your buildings work better. Superior Withair® design makes our units among the quietest and most efficient on the market. A Withair® water source heat pump is easy to access and service components; meets high indoor air quality standards; offers quiet operation; and higher operating efficiencies to reduce total cost of ownership. Efficient systems for lighting, plumbing, and comfort can significantly reduce the operating expense of doing business. The extra high efficiency units provide energy savings that not only contribute to lowering the life cycle cost, but also reduce the waste impact on the environment.

The reliability, efficiency and comfort provided by Withair® water source heat pumps is evidenced by the owners, designers,and contractors that have placed their trust in our units in thousands of installations worldwide.
