Ultra-Low NOx Premix Gas Burner
Riello RX 1800 S/E ULN
The Riello RX 1800 S/E ULN is an ultra-low NOx modulating premix gas burner covering 300 to 1940 kW. Gas is introduced downstream of the fan, so a sealed ventilation structure is not required, while independent servomotors manage the air-fuel ratio across the modulation range.
Applications
Condensing boilers and district heating systems that must meet strict NOx limits.
Industrial process heat in food, chemical, paper, textile, paint and petroleum sectors.
Why buyers choose it
- Ultra-low NOx premix technology meets restrictive emission limits.
- Asynchronous fan motors and pilot ignition system ensure reliable high-power combustion.
- Digital burner management controls air-fuel ratio with independent servomotors.
- High modulation ratio matches load swings in condensing boilers and industrial processes.
- Gas introduced downstream of the fan avoids need for sealed ventilation structure.
