Reznor UDSA Gas-Fired Air Heater

UDSA gas-fired air heaters – efficient, even at peak performance

The most well-known device from REZNOR is the UDSA gas-fired air heater, which ensures even air distribution in industrial halls. This easy-to-install recirculating air unit is available in 14 output 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 outside or from the hall itself.

The UDSA gas-fired 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 trendsetting.
With this generation of devices, halls can be heated in a particularly economical way directly – that is, without central heating – using decentralized, modulating gas-fired air heaters.
