Master B230 Direct Fired Oil Heater 65 kW Without Flue Gas

The Master B230 Direct Fired Oil Heater is a high-performance heating solution engineered to deliver a substantial heating capacity of 65 kW. Designed for rapid and efficient space warming, this direct fired oil heater operates without flue gas extraction, making it exceptionally effective in environments where high air exchange is present. Built by Master, a trusted name in climate control equipment, the unit ensures dependable operation and robust performance for demanding professional applications.

Advantages

This direct fired oil heater offers high thermal efficiency, ensuring that nearly all generated heat is distributed directly into the target space for fast temperature rises. Its heavy-duty construction is designed to withstand harsh working conditions on construction sites and in industrial environments. The integrated safety features, including photocell flame monitoring and thermal overload protection, ensure safe operation during continuous use. Additionally, the mounted wheels and sturdy handles facilitate easy transport and repositioning across large workspaces.

Suitable for

• Drying and heating construction sites and newly plastered walls
• Providing temporary or permanent warmth in large warehouses and logistics centers
• Heating agricultural buildings, livestock facilities, and greenhouses with high ventilation
• Rapidly warming workshops, garages, and industrial manufacturing spaces

When it may not be suitable

This unit is not suitable for enclosed, unventilated indoor spaces, residential rooms, or offices, because direct fired heaters release combustion gases directly into the environment. It should also be avoided in areas where sensitive materials, livestock, or humans are present without a continuous supply of fresh air.

Key specifications

• Heating capacity: 65 kW
• Air displacement: 3000 m³/h
• Fuel type: Diesel or kerosene
• Fuel consumption: 5.2 l/h
• Power supply: 220-240V / 50Hz
• Ignition system: Electronic

How to use

Position the oil heater on a flat, stable, and non-flammable surface in a well-ventilated area away from combustible materials. Connect the unit to a compatible power source and fill the fuel tank with clean diesel or kerosene. Adjust the thermostat to the desired temperature level and switch on the device. The electronic ignition system will automatically start the burner. Ensure that proper ventilation is maintained at all times during operation to allow safe air exchange.

What to consider before purchase

• Verify that the intended application area has sufficient ventilation to handle direct combustion emissions
• Check the electrical supply requirements to ensure compatibility with the power source
• Calculate the required heating capacity based on the volume of the space and ambient temperature
• Ensure a reliable supply of approved fuel such as diesel or kerosene

Usage recommendations: Regularly inspect the fuel filter, ignition electrodes, and photocell for cleanliness to maintain optimal operating efficiency. Always allow the unit to complete its cooling cycle before unplugging it from the power source.
