Master B300 Oil Fired Space Heater

88kW industrial heater with dual chamber design

Portable, professional and powerful – the Master B300 Direct Oil Fired heater offers one of the most efficient and reliable all round heating and drying solutions of any unit of this size and style on the market today. Featuring a duel barrel design, the Master B 300 was specially built for regular or intermittent use in industrial or commercial environments including warehouses, factories, workshops and more, and is certainly built to last. This is in no small part due to its strong and robust outer shell, stainless steel combustion chamber and thermally protected motor to go towards ensuring a longer service life.

The Master B300 has features that expand its applications beyond those of similar units, including integrated trolley and a relatively lightweight chassis for moving around or between sites, easily serviceable parts including oil and suction filters and an oil tank level indicator. The chambers can also be operated independently to suit your application purpose.
