UDSA Gas-Fired Air Heater – Efficient, Even at Peak Performance

The most well-known device from REZNOR is the UDSA gas-fired air heater, which ensures uniform air distribution in industrial halls. This air heater, which is easy to install, is available in 14 sizes ranging 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 hall, as standard.

The UDSA gas-fired air heater from REZNOR ensures uniform air distribution in the heated hall. Its patented heat exchanger sets new standards in terms of flow behavior and heat transfer and ensures an efficiency of over 92 percent.

UDSA: compact, revolutionary, and groundbreaking.
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.
