The company’s custom air-handler line allows units to be designed for demanding applications in new or existing buildings. With a wide selection of options and unique 2-inch variable dimensioning, custom-built air handlers provide unlimited configurations, giving engineers and contractors design flexibility. The custom air-handler line can even provide a viable solution for demanding applications where increased filtration is needed. With the ability to attain a maximum of Class 6 leakage, the units can be customized for use in health care facilities, clean rooms, or labs. With modular design flexibility, engineers have the ability to vary the length, width, or height in 2-inch increments, so that custom air-handling units can easily be designed to fit into critical spaces and through fixed doorways. Options are available to add access and service vestibules, or to choose the type of door handle and swing. The low-leakage cabinet construction incorporates a patented splice collar design and welded frame channels that eliminate the need for field-installation caulking and associated costs. The custom air-handler line also provides engineers with the ability to maximize energy efficiency with a variety of energy options including energy recovery wheel, direct-drive plenum fan array, and extensive coil selections.
