Applications
Hot or superheated water boilers, steam generators and diathermic oil boilers.
Food, chemical, paper, textile, paint and petroleum industrial processes.
Why buyers choose it
- One burner fires both light oil and natural gas for fuel flexibility.
- Gas-side modulation with PID logic reduces fuel consumption and running costs.
- Optimized air suction circuit and sound proofing keep noise emissions low.
- High-efficiency fan and combustion head deliver stable performance across firing rates.
- Reduced dimensions and simple layout ease installation and maintenance.
