KLIMOSZ LE with retort burner



Klimosz boilers from the LE series are a product that meets the most stringent requirements of emission and ecological standards. Minimizing environmental pollution is the result of a carefully thought-out design of the device. Monthly tests have led to obtaining the highest possible efficiency (up to 91%) while maintaining the minimum emissions of harmful substances. Klimosz LE series have a "5th class" highest emission standard and EcoDesign certificate for granulated coal. 

Klimosz LE has a highly efficient flame exchanger made of the highest quality P265GH boiler steel. A heat exchanger of this type has a very large heat recovery area from flue gas, which directly translates into high boiler efficiency. 

Klimosz LE is reliability and safety. The boiler has several independent thermal protections: boiler temperature sensor, feeder tube temperature sensor (in the case of detection of heat in the feeder pipe, the fuel pushes out emergency and switches off the fan). The boiler also has a safety device that works without the need for electricity in the form of a "firefighter" flooding the tank in an emergency.
