For a long time Reznor has been providing the best heaters for a variety of applications. Reznor has improved their already industry leading technologies with the UDX line of unit heaters. Featuring a new, sleeker design, Reznor units still offer efficiency and easy installation.
Offering an industry leading 82% thermal efficiency and a variety of different BTUs, the UDX series of heaters offer exceptional heat performance for areas both large and small. The 30,000 - 120,000 BTU models are all approved for use in commercial buildings as well as attached residential garages. The UDX60 (60,000 BTU) is ideal for medium spaces. For larger, commercial spaces, UDX units come in a variety of BTUs from 150,000 up to 400,000. Call or email us for an estimate of the number of BTUs you need for your location.
These Reznor Heaters are easy to install, secured in place from 2 or 4 suspension points or by an optional hanger kit that allows for ceiling mounting. Thermostat 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. The factory installed gas line input is located on the backside of the unit heater making the gas connection simple.
Reznor has made improvements to their UDX heaters for better performance and quality of use. Features include Reznor’s patented TCore² titanium stabilized aluminized steel heat exchanger, as well as the "G" terminal to the strip and a newly designed circuit board, which allows for fan-only operation without adding relays. Outwardly, Reznor has developed a sleeker design that shows no front or bottom hardware. The newly designed cabinet has external status indicating LED lights, a hinged door for easy access to the control panel and a removable front face. Look for the unique white and black powder coated unit with the bright red Reznor logo and angled corner to know you have a genuine Reznor unit.
