  • Description

    For a long time Reznor has been manufacturing the best heaters for a variety of applications. The UDAP75 unit heater was created as the next generation of Reznor products. It features easier installation, improved efficiency, and a totally new design.

    With an industry leading 83% thermal efficiency and 12 different sizes, the UDAP series of heaters offer exceptional heat performance for areas of any size. The 30,000 - 125,000 BTU models are all approved for use in commercial settings as well as attached residential garages, including this unit, the UDAP75 (75,000 BTU), which is ideal for midsize spaces. Contact us to get a more accurate estimate of how many BTUs are needed for your space.

    Reznor unit heaters are easy to install, secured in place from 2 or 4 suspension points or by an optional Quick-Sling mounting bracket that allows for ceiling mounting. Controller setup is quick, with a low-voltage terminal strip on the outside of the cabinet that makes connecting control wiring simple with no panels to remove. All units also have a factory installed gas line nipple to the exterior of the cabinet, for easy gas service connection.

    Reznor is constantly making improvements to their heaters. A key new feature is the patented TCore2 titanium stabilized aluminized steel heat exchanger. They also added a "G" terminal to the easily accessible rear terminal strip which allows for easy setup of fan only operation. Outwardly, Reznor has developed a sleeker design that shows no front or bottom hardware -- look for the unique white unit with deep red louvers, black side handle, and angled corner to know you have a genuine Reznor unit.
