• Total independence from the fixed power grid: The 18 VDC battery power supply allows for operation in total mobility even on construction sites without electrical connections or external generators, eliminating the clutter and danger of cables on the ground.
• Modulatable and powerful thermal output: The ability to adjust the thermal power from 18 to 30 kW allows the operator to adapt the heat level to the actual size of the room or to industrial climatic conditions.
• Immediate and odor-free heating: High-efficiency combustion instantly develops a hot air flow of 650 m3/h with practically non-existent odor emissions, making the unit optimal for indoor workshops.
• Maximum portability and reduced fatigue: With a net machine body weight of only 5.2 Kg and a 666 g battery module, the generator is extremely lightweight and can be transported and repositioned anywhere with one hand.
• Robust accumulator for extreme conditions: The 5.2 Ah 18650 lithium-ion battery guarantees safe operation in a wide climatic spectrum, withstanding operating discharge temperatures from -20 °C up to 60 °C.
• Automated thermal safety: Integrated thermal sensors constantly monitor the operation of the metal shell, automatically blocking the flow of LPG or propane gas in case of overheating risk.
• Active gas leak prevention: The safety valve intervenes promptly in case of accidental flame extinction, instantly interrupting the fuel flow to protect the department staff.
• Guaranteed anti-tip stability: The lower control box is structured with a low profile to act as a stable supporting base, preventing accidental falls on unstable construction site floors.

This cordless gas hot air generator finds its optimal application in rapid heating and flexible temperature control within construction sites without power lines, mechanical workshops, indoor craft laboratories, logistic warehouses, temporary storage areas, garages and partially ventilated industrial environments. Thanks to a maximum power of 30 kW, a significant air flow of 650 M3/H and full compatibility with standard LPG or propane G30 cylinders, it represents the perfect tool to meet the needs of mobile craftsmen, carpenters, building installers and emergency maintenance teams who require instantaneous, clean heat and independence from power outlets.

The h923_25 model is the right choice when the professional context requires a cordless industrial gas heater (18 VDC) that combines high air flow (650 m3/h) with maximum freedom of movement in the field, without excessive weight. It is widely preferable to traditional corded generators or diesel models because the 5.2 Ah lithium-ion battery technology combined with external supply from a G30 cylinder at 700 bar eliminates greasy fumes, removes the need for dedicated electrical panels and reduces the empty machine weight to just 5.2 Kg. Choosing this plug-and-play cordless system means investing in a robust, safe manual heating system capable of operating in freezing environments down to -20°C.

What are the advantages and operational specifications of the lithium-ion battery integrated into this generator?

The h923_25 generator uses an advanced battery pack consisting of 18650 lithium-ion cells, with a nominal voltage of 18 VDC and a nominal capacity of 5.2 Ah, weighing only 666 g. This cordless technology allows you to operate the 650 M3/H fan anywhere. To preserve cell efficiency over time, charging must take place at temperatures between 10 °C and 45 °C, while discharge during operation supports extreme conditions from -20 °C to 60 °C. For prolonged storage at rest, it is recommended to keep the battery in an environment between 10 and 25 °C.

How do the absence of an internal tank and battery operation affect the machine’s maneuverability?

Unlike industrial diesel generators, which are heavy and tied to large fuel tanks and 230V electrical outlets, this model is structured to connect to an external gas cylinder and to be powered exclusively by battery (DC18). This design allows the net structural mass of the generator to be reduced to only 5.2 Kg and to maintain extremely compact dimensions (475x222x365 mm). The operator can therefore lift and reposition the unit within the construction site with one hand and without any effort, using the ergonomic top handle.

What safety systems govern the gas flow and protect the steel shell from any accidents?

The machine is passively protected by a robust shell enclosed in a powder-coated steel casing, designed to withstand high operating temperatures and mechanical site shocks. From an active point of view, the generator is equipped with integrated thermal sensors for protection against overheating, which automatically stop the gas supply if the internal temperature exceeds safety limits. Furthermore, a safety valve against accidental flame extinction instantly blocks the flow of LPG or propane G30 gas at 700 bar to prevent toxic leaks, while the lower control box acts as a solid anti-tip base.
