⚡ At a Glance
- • Heating Performance: 20 kW output, heats 220-300 m², 550 m³/h airflow
- • Best for: Workshops, building sites and agricultural spaces needing sustained portable heating
- • Not ideal for: Domestic rooms where ventilation and kerosene fuel are unsuitable
High-output diesel heater with digital thermostat and clear fuel-level monitoring. Multiple automatic safety cut-outs and steel housing suit demanding site environments.
Extended runtime - with efficient 20 kW combustion and low fuel consumption
The combustion system runs at about 1.65 litres per hour and the large onboard fuel tank provides roughly 11 hours of operation from a full tank. Continuous burn is supported by 550 m³/h airflow for effective heat distribution.
Extended operating periods minimise refuelling interruptions, useful for full work shifts or multi-day projects.
Accurate climate control - with a digital thermostat and wide setpoint range
Digital temperature control allows setpoints between 5°C and 55°C and displays current readings, while the system is rated to operate reliably across ambient conditions of -20°C to 40°C. Built-in modulation keeps output aligned with the selected temperature.
A steady workshop temperature protects materials and keeps crews comfortable without constant manual adjustments.
Site-ready safety and durability - with multiple automatic protections and steel housing
Safety systems include automatic fault shutdown, fire-off protection, overheat protection and overcurrent protection, while a diagnostic light aids fault identification. The unit sits in a reinforced steel housing with a carry handle for movement.
Multiple protections reduce downtime and risk in busy environments, while the reinforced carry handle aids relocation between sites.
