  • Description

    Reznor is known for engineering quality heaters that can be used for a variety of needs. The UDAP400 unit heater was created as the next generation of Reznor products. It features a simpler installation process, improved efficiency, and a totally new design.

    Boasting an impressive 83% thermal efficiency, Reznor’s UDAP unit heaters provide high-quality heat performance and are available in 12 sizes to heat small garages all the way up to large warehouses and industrial buildings. This unit, the UDAP400 (400,000 BTU), is approved for commercial use only, and is ideal for large industrial spaces and warehouses. Feel free to contact us for a more specific calculation for BTU sizing requirements.

    The UDAP Series heaters can be mounted using either 2 or 4 suspension points. For a simpler installation, add on our Quick-Sling mounting bracket. Controller setup is simple, with a low-voltage terminal strip on the outside of the cabinet that makes connecting control wiring simple with no panels to remove. The factory installed gas line input is located on the rear of the heater making the gas connection quick.

    Reznor has made improvements to their UDAP heaters for better performance and quality of use. New features include Reznor’s patented TCore2 titanium stabilized aluminized steel heat exchanger, as well as the addition of a "G" terminal to the strip and a newly designed circuit board, which allows for fan-only operation without adding relays. A sleek new look makes for a clean front and bottom with no visible hardware. Reznor's unique style with it's deep red louvers, white cabinet, and angled corner let you know that you have purchased the top heater.
