Why buyers choose it
- Engineered for large thermal loads, the RX 1800 S/E premix burner delivers low-NOx combustion with very high modulating turn-down ratios.
- A brushless Riello motor governs fan speed and gas proportional valves for precise, stable power output across the full range.
- Efficient air-gas premixing with fan-speed control holds steady part-load combustion — ideal for boilers with wide demand swings.
- Supplied with or without acoustic cover, in standard or airtight (low-NOx) configuration to suit the boiler room.
- The open, versatile electronic control integrates easily with plant monitoring and building-management systems.
Applications
The RX series suits food, chemical, paper making, textile, paint and petroleum plants that need low-emission, tightly controlled gas firing at higher capacity.
Its high turn-down ratio keeps combustion stable at part load, saving fuel across variable-demand processes.

Buyer Questions
Riello RX 1800 S/E Premix Burner FAQs
What is premix combustion in the Riello RX 1800 S/E?
Premix means gas and air are mixed before reaching the combustion head, giving a perfect air-gas mixture, low emissions and high efficiency across the RX family.
Is the RX 1800 S/E modulating or two-stage?
It can run two-stage progressive or modulating, and is available with or without cover, in standard or airtight configuration.
How is power output controlled?
A Riello-designed brushless motor controls fan speed and the gas proportional valves, delivering precise power output control even at high capacity.
Can the RX 1800 S/E integrate with plant controls?
Yes. Its electronic control is an open and versatile system, designed to integrate with broader combustion and monitoring setups.
