The Master B 70 diesel heater ensures efficient localized heating in a wide range of situations.
This series of direct-combustion diesel or kerosene heaters is ideal for heating medium-sized, well-ventilated areas, as well as for drying in the construction sector.

The operating principle of these portable hot air generators is based on a rotary compressor which, by conveying pressurized air to the burner nozzle, creates a vacuum that allows fuel to be drawn from the tank.
The resulting air-fuel mixture is then vaporized and ignited in the combustion chamber, which is constantly cooled by external air pushed by the fan towards the front outlet, ensuring 100% thermal efficiency.

All hot air generators are equipped with safety devices to control the flame, prevent the risk of overheating, and optimize fuel consumption.
The combustion chambers are also made of special stainless steel treated to withstand high temperatures over time.
The combustion products are essentially water vapor and carbon dioxide (CO2), with minimal emissions.


This Master heater is entirely produced in Italy. Made in Italy is synonymous with precision and high technical quality.
