ExEco gas burners

Modulation gas burners ExEco BS/M 3-4

The BS series is modulated. The power changes smoothly within the range, the fuel/air ratio is maintained by a cam with a variable profile. To work in the modulating mode, you need a temperature or pressure sensor and a PID controller.

Frequently asked questions

What is the capacity of ExEco BS/M burners?
The thermal power range of the series is 48-250 kW.
What type of regulation does ExEco BS/M have?
Modulating with mechanical control: cam with variable profile, servo drive and thrust. For modulation, you need a sensor and a PID controller.
What kind of gas do ExEco BS/M burners use?
As standard, on natural gas. Most models can be converted to LPG (propane-butane) with a conversion kit; the work must be carried out by a certified engineer.
Is ExEco BS/M suitable for a boiler from another manufacturer?
Yes. The burners are universal and mount on boilers of both Russian and foreign makes. What matters is selecting the correct size and combustion head length for the specific boiler.
What should I state when ordering?
Boiler output, gas type and mains pressure, control and emission requirements, and the distance from the flange to the furnace. If you do not have the parameters, send the boiler model and we will make the selection.
What are the delivery times?
Fast-moving sizes ship from stock, the rest is made to order. The exact lead time and price are confirmed in the quotation. Delivery across Russia and the CIS.
What do I need to buy for the modulation mode?
A temperature or pressure sensor and a PID controller. Without them, the burner operates in a two—stage progressive mode - this is a standard option.
