DUO INDUSTRIAL with one retort burner



Klimosz boilers from the DUO INDUSTRIAL 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 ~90%) while maintaining the minimum emissions of harmful substances. Klimosz DUO INDUSTRIAL series have a "5th class" highest emission standard certificate for granulated coal or pellets (detailed information which about compliance with the ecological standard is provided in the table at next page).

Klimosz DUO INDUSTRIAL 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 DUO INDUSTRIAL 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). Also, big power boilers (50kW and more) requires STS safety valve. This valve is connected to the water supply network and floods fuel tank with cold water in case of an emergency (when the fire reaches the feeder pipe, the temperature sensor from the safety valve will give a signal to open the valve and flood the fuel tank and extinguish the fire). It provides reliable boiler's fuel tank protection and works without electricity.

The variable outlet of the flue makes it easier to connect the boiler to the chimney whether it is led vertically or horizontally.

Arrangement of the connections on both sides of the boiler to C.H. and H.U.W.: simplifies assembly and reduces assembly costs.
