DC18SP is a new model 2018 with servo at the air intake. There also must be a special burner A25 for DCxxSP boilers code H0048. It also has servo for air controll.
For DCxxSP, CxxPS boilers is appropriate burner. ATMOS A25 (for models DCxxSP, CxxPS) 4,5 - 24 kW code: H0048.
INFO - DCxxSP and CxxSP boilers and burners in version Model 2018 are equipped with the function of automatic closing or opening of the air supply to the boiler/burner (using the actuator) when hearing with wood or pellets.
The boilers are equipped with an AGF2 flue gas sensor and a KTF20 boiler water temperature sensor for function of automati burner start after the wood burns out. Than the boilers are equipped with two KTF20 sensors (TV and TS) for controlling the burner with two temperatures on the accumulation tank. The whole set is sold in the maximum range, for fully automatic mode and simple plug and play installation.
The boiler Atmos DC 18 SP proper is constructed as a body of three chambers situated one above another. The two upper chambers serve for the gasification of the wood, as you are familiar with from the classical gasification boilers that we produce as the standard. In the third, lowest chamber, is installed the required burner at the front, inlaid by ceramics to ensure the optimal quality of burning. Both the systems are separated by a water jacket so that they do not interfere with each other and, thanks to that, the boiler achieves high effectiveness when heating by the individual fuels. The combustion gases exhaustion is handled by one outlet and therefore only one flue is needed.
The operation of the Atmos boiler DC 18 SP is fully automatic to heat up water to required temperature with high efficiency and in a good quality of burning.
