Built for High Performance and Quality Results, Designed to Optimize Your HVAC System.
Withair® air handlers provide advanced technology and custom features in streamlined, easy-to-install packages. Indoor and outdoor units are available to handle a wide variety of applications. Indoor and outdoor air handlers are used to condition and circulate large volumes of air throughout the space via ductwork. Air handlers are part of a system using either a chiller with cooled water or a condensing unit in a direct expansion (DX) system. Dictated by local codes and based on the application, each air handler will have a different set of needs including, but not limited to, fresh air intake, humidity control, heating, filtration, and energy recovery. In general, an air handling unit will use a mixture of outside air and recirculated air from the building to filter, cool, and heat. Energy recovery devices are used to transfer heat or moisture from exhausted air to supply air, or vice versa. This helps to reduce energy usage while providing fresh air to the building.
Withair® continually invests in air handler research and development of new products to adapt the changing needs of today's HVAC market. Our focus on whole systems has led to the design of many custom options that can be incorporated into standard cataloged air handler, providing a more cost effective solution than a completely custom-built unit. These custom-engineered air handler solutions are offered as offered as factory-packaged specials that deliver Trane quality, enable simplified on-site installation, and provide proven, tested performance. The air handler solutions address such issues as humidity control, energy recovery, special acoustical needs, air filtration and the use of optional fuel sources. Withair® air handlers can help HVAC systems achieve higher energy efficiency and indoor air quality while reducing maintenance requirements – adding life to buildings and improving the lives of people within them. From the most straightforward needs to wide-ranging demands for air cleaning, dehumidification and energy savings, there’s a Withair® air handling unit to deliver everything your project requires.
Withair® Air Handling Units provide design flexibility that balances performance and economy without compromising quality. With a full line of standard, semi-custom and custom air handling units to choose from, we have a system perfectly aligned to your building's needs and budget.
