Selas Combustion Controller Valves: Complete Mixing of Fuel Gas and Air for Maximum Efficiency
Selas Combustion Controllers are precision premix systems for blending fuel gas and air. They are suitable for most fuels, mixing them with room air and compressing the mixture to deliver a preset gas/air ratio at uniform pressure to the burners.
Selas combustion controllers are available with two valve types:
- Posimix valves for applications requiring constant heat
- CAV valves for processes requiring variable heating
