Reznor UDSA Gas Warm Air Heater
UDSA Gas Warm Air Heater – Efficiency at Its Best

The most renowned unit from REZNOR is the UDSA gas warm air heater, which ensures uniform air distribution in industrial halls. This easy-to-install recirculating air unit is available in 14 output sizes ranging from 7 to 97 kW, and comprises a heat exchanger, gas burner, and an exhaust fan. The combustion air can be sourced either from outside (standard) or from the installation area.

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

UDSA: compact, revolutionary, and forward-looking.
This new generation of units enables particularly economical direct heating of halls—meaning without a central heating system—using decentralized, modulating gas warm air heaters.

REZNOR UDSA Gas Warm Air Heater: The Advantages:

- Efficiency over 92%
- Suitable for vertical installation
- Low NOx emissions
- Innovative combustion concept
- Quiet operation

These units are directly heated gas warm air generators (WLE) with fan-assisted atmospheric multi-gas burners. Installation of the gas WLE and the connection for gas and exhaust side must only be carried out by an authorized installation company.

The gas WLEs are suitable for:
- Operation with natural gas or LPG
- Recirculated air operation
- Inlet temperatures below 5°C with stainless steel heat exchanger *
- Heating operation single-stage, or two-stage control* via room thermostat and heating control switch
- Ventilation° control via ECOtronic TN-L° with day/night/week program
- Flue gas discharge through the roof, versions B or C°
- Flue gas discharge through external wall, version C°
