Thermal Insulation

The external cover consists of galvanized and pre-coated steel panels with thermo acoustic insulation and a control panel in
laminated steel sheet. Each element is individually fixed to the supporting framework and is easily removable to allow access to the inner workings of the heater

Combustion Chamber  and Heat Exchanger

The cylindrical combustion chamber is in aluminized steel and features heat exchange tubes interconnected with turbulators in
stainless steel. The heat exchange surface is very extensive and its resistance to high temperatures is exceptional.

An environmentally friendly and high efficiency Oil Burning Heater has always been our objective.

For this reason we combine our FH warm air heaters with burners of the highest technology and reliability, in order to obtain “clean” combustion, without any unburnt oil and with a reduced level of polluting elements. Minimal environmental impact, protection of the environment and at the same time much lower maintenance costs thanks to maximum protection of the heat exchange surfaces… the advantages of our oil burning heater range are never ending !

Versions with elevated temperatures and pressure

Dedicated principally to industrial applications such as processing plants, industrial furnaces and controlled-temperature environments with a high level of air filtering. This version can also be used for the heating of industrial environments. Automation and thermo regulation systems can be designed for every application. Below is a our oil burning heater, configured for a duct warm air heating system, which has an up-rated fan pressure.
