Oil heating

Direct firing

Directly fired integral heat exchangers with oil burners for heating supply air. Integral heat exchangers are designed specifically for heating the supply air in ventilation systems and air handling units. These heat exchangers can be operated with light fuel oil. For oil firing in the partly condensing range, use low sulphur fuel oil to DIN 51603-1. They are made entirely from stainless steel. In terms of their design and the application of different stainless steel qualities, heat exchangers are differentiated depending on application area, such as dryers in process air handling units with a maximum discharge temperature of 300 °C or air handling and air conditioning units with a maximum discharge temperature of 100 °C. Ensure that the installation site offers an adequate supply of combustion air. Generally, flue gases must be discharged via chimneys.

To protect against overheating, hot air generators with directly fired heat exchangers must be equipped with a high limit safety cut-out with manual reset as well as high limit temperature cut-outs. To prevent damage from the heat exchanger overheating, the residual heat following a plant shutdown must be dissipated through an appropriate run-on period of the supply air fan.

DHW/hot water generation

Generating DHW with advanced modulating oil condensing technology. Suitable for standard extra light fuel oil or extra light low sulphur fuel oil. The oil burner can be operated with commercial fuel oil qualities to DIN 51603-1. For this burner, we recommend low sulphur fuel oil, but as a minimum, a fuel oil with no more than 1000 ppm sulphur content. The boiler body is constructed from sulphuric acid-resistant stainless steel 1.4539. Advanced blue burner technology initially converts the oil fully into a gaseous state by mixing it to an optimum degree with combustion air, before burning it in a blue flame which ensures clean (low NOX) combustion. The complete combustion in the blast tube generates no soot and almost no CO. Condensing technology without a set minimum amount of circulation water. The oil burner features a large water content and can therefore be regulated without major temperature fluctuations. An overflow valve, which would be detrimental to the condensation inside the boiler, is not required. As an option, the condensing boiler can also be teamed up with a DHW cylinder. Powerful freestanding DHW cylinders with capacities from 120 to 300 l provide domestic hot water both conveniently and exactly as required. The affordable PP flue system reduces the overall outlay for the oil condensing system. The universal peroxide gaskets enable the use of the same flue systems for gas and oil condensing boilers.

Control is provided by an intelligent, weather-compensated control unit with a very straightforward operating concept. Control units for additional circuits with mixers, cascades and the integration of solar thermal systems round off our diverse range of applications for our oil condensing boilers. The burner can also be delivered with a user interface for connecting an external control unit.
