  • Description

    Reznor heaters have a long-established reputation for quality heat in a variety of applications. The V3 Series unit heaters were built to improve upon Reznor’s already excellent technology, and feature better efficiency, easier installation, and a new design both in and out.

    Boasting an impressive 83% thermal efficiency, Reznor’s UDAS heaters provide a high-quality heat performance and are available in 14 sizes to suit a range of heating needs. This unit, the UDAS-175 (175,000 BTU), is approved for commercial settings only, including warehouses, professional garages, and other industrial spaces.

    The defining feature of the UDAS models is their design as separated combustion heaters, meaning that the air used for combustion is pulled in from the outside or another room. This process helps ensure that all air introduced to the inside of the heater is fresh and free of harmful particulates, making these heaters particularly useful in settings where chemicals are stored or frequently used, and/or humidity levels tend to be high.

    The V3 Series heaters are easy to install, secured in place from 2 or 4 suspension points. Electrical set-up is easy as well, 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 has made improvements to both the ins and outs of their UDAS 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. Externally, 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 by Thomas & Betts.
