Everything you need to know about our burners and parts
What types of liquid fuel can Bairan burners run on?
Bairan burners are universal and can run on cooking oil, mineral oil, untreated oil, and waste oil efficiently without clogging.
How does compressed-air atomising work?
Compressed-air atomising keeps the fuel openings wide, allowing particles up to 0.2 mm to pass straight through without blocking the nozzle.
Which burner model should I choose for my boiler?
It depends on your heating output requirements. STW120 covers 10–50 kW, while STW133-2 covers 50–100 kW. You can also use our online burner finder calculator.
Do I need a separate compressor for the STW120?
Yes, STW120 requires a piston compressor of at least 1200 W, or you can opt for our silent compressor accessory.
