Oil heaters

Heat evenly and efficiently

Arska heaters are known for their excellent efficiency and clean burning without soot residues. Even though the heater’s external dimensions are minor, they are sustainable and their oil consumption is low.

With top quality materials and clever design, we’ve made the heaters easy to maintain. Outer walls are made from galvanized steel, which withstands even harsh circumstances.

In a cylindrical furnace, the flame burns freely in the middle and heats evenly. The furnace is made of high quality special steel, and which temperature level of peeling is 1050°C.

Vacuum heater provides sufficient heat power economically and efficiently for large dryers as well. Vacuum heaters are equipped with burner rain cover.
