Reznor UDSA Gas-Fired Warm Air Heater

UDSA Gas-Fired Warm Air Heater – efficient, even at peak performance

The most well-known unit from REZNOR is the UDSA gas-fired warm air heater, which ensures even air distribution in industrial halls. This easy-to-install recirculating air unit is available in 14 performance sizes, from 7 to 97 kW, and consists of a heat exchanger, gas burner, and an exhaust gas fan. The combustion air can be drawn either from the outside or from the room, as standard.

The UDSA warm air heater from REZNOR guarantees even air distribution in the heated hall. Its patented heat exchanger sets new standards in terms of flow behavior and heat transfer, ensuring an efficiency of over 92 percent.

UDSA: compact, revolutionary, and groundbreaking.
With this generation of units, halls can be heated in a particularly economical way – directly, that is, without central heating – using decentralized, modulating gas-fired warm air heaters.
