Manual marking machine H75/25

The Hofmann H75/25 is a hand-guided spray thermoplastic road marking machine for small-scale marking operations and as a complement to self-propelled spray thermoplastic machines. The machine dimensions are 1,500 mm (L) x 1,050 mm (W) x 1,150 mm (H) with an operating weight of approximately 250 kg. The material container holds up to 25 liters of spray thermoplastic. The glass bead container holds 20 liters, with an optional pressure bead container of 22 liters (maximum 1.0 bar) available for higher-volume bead application. Both the material container and the spray gun are indirectly heated via thermal oil, which is in turn heated by a propane gas burner — maintaining spray thermoplastic material at application temperature throughout the operation. The gun-to-surface distance is adjustable, allowing the operator to control line width and spray pattern geometry for different surface and line width requirements. Marking line widths range from 10 to 30 cm. Air and gas supply are connected via hoses directly from a marking machine or from a separate compressor and gas cylinder set. Minimum required air output is approximately 600 liters per minute.

The thermal oil heating system transfers heat uniformly to both the material container and the spray gun body — maintaining the material and gun at consistent application temperature without direct flame contact on the spray thermoplastic compound. This indirect heating method prevents localized overheating of the material near the heat source and keeps the spray gun at the temperature required for consistent atomization and spray pattern geometry across the full marking pass. The adjustable gun height allows the operator to compensate for surface irregularities and to optimize the spray fan width for different required line widths between 10 and 30 cm without changing the spray gun nozzle. Compatible cookers include the D/ID Series and HK Series Hofmann vertical and horizontal cookers for material supply.

The Hofmann H75/25 is deployed by road marking contractors for small-scale spray thermoplastic marking work — including symbol and legend markings, pedestrian crossing refreshes, short line sections, cycle lane markings, and repair work on existing spray thermoplastic markings — and as a supplementary marking unit alongside self-propelled spray thermoplastic machines on larger projects where the main machine cannot access confined zones or tight working areas.

Leader Infra supplies this hand-guided propane-heated spray thermoplastic marking machine for road marking contractors — delivering indirect thermal oil-heated gun and container operation across 10 to 30 cm marking widths in a 250 kg unit suited for both standalone small-scale spray thermoplastic work and machine-complement operations.

FAQ — Why is the H75/25 supplied with air and gas via hoses from a marking machine rather than carrying its own compressor? The H75/25 is designed as a compact supplementary unit — carrying a built-in compressor and gas supply would add significant weight and complexity to a machine intended for small-scale and confined-access operations. Connecting to an existing self-propelled marking machine’s compressed air and gas supply keeps the H75/25 lightweight and maneuverable, while the separate compressor and gas cylinder set option allows fully independent deployment at sites where no marking machine is present.
