M7 High Efficiency Airplate


Improve combustion efficiency with better control of secondary air

Proper and efficient combustion is critical to the performance of a natural draft heater. The Secondary Airplate was developed specifically for atmospheric heaters and can improve operational efficiency by controlling excess airflow.

Combined with the right burner selection, combustion analysis, and correct fuel train pressure setting, the addition of a Secondary Airplate can have a substantial affect on your heater’s combustion efficiency. Users will often experience an increase in combustion efficiency of 30% or more resulting in positive impacts to your bottom line, including reduced fuel gas and emissions. Profire Secondary Airplates protect your assets by improving firetube longevity and reducing or eliminating flame impingement.

Available in Pilot and Slipstream models.
