WITH INDIRECT AND DIRECT HEATING
Borum thermoplastic preheaters are melting, heating and mixing the thermoplastic material making it ready for application via the road marking machine.
Borum preheaters are designed in two different systems:
- Direct heating (D): The thermoplastic material is heated directly from the burner.
Standard capacities : 300 L, 500 L, 750 L, 1000 L
- Indirect heating (ID): The thermoplastic material is heated via thermal transfer oil in a separate chamber heated by the burner.
Standard capacities: 250 L, 400 L, 600 L, 800 L, 1100 L, 1600 L, 2500 L
For trouble-free heating of block, granulate or liquid thermoplastic material. Efficient vertical double mixer arms, which ensure uniform heating of the material. 50 mm heat insulation. Hydraulic forward/reverse transmission. Preheaters driven by a hydraulic power unit, which can be installed independent of location of preheater. Standard length for connection of hoses and cables 6.0 m. Diesel oil burner or propane gas system can be supplied for heating. All sizes of preheaters up to 1600 can be delivered as double (twin) units driven by a common BM PS-15 power unit.
Hydraulic motor with agitator bearing. Start/stop/reverse valve for agitator drive. Vertical agitator with double arms and paddles. Material container surrounded by heat transfer oil, to distribute heat. Oil-heated center pipe in material tank. Oil-heated material outlet. The preheater is equipped with a thermostat for thermoplastic material and for heat transfer oil temperatures from +50 to +270°C. Includes an integrated display showing actual temperatures.
Hydraulic motor with agitator bearing. Start/stop/reverse valve for agitator drive. Agitator with double arms and paddles. The preheater is equipped with a thermostat for thermoplastic material temperatures from +50 to +250° C. Includes an integrated display showing actual thermoplastic temperature.
Filling system for transportation and lift of thermoplastic, mostly used for transporting thermoplastic from preheaters placed on a supply truck/ trailer to a material tank placed on the marking truck. Borum has the following filling systems: TLS 1 - for connecting to a single preheater. TLS 2 - for connection to double preheaters. The units have a hydraulically driven piston pump. The bottom part and material pipe is heated by heat transmission oil, which is circulated by a hydraulically driven pump. When run by a standard PS 15, the capacity is 40 litres/min. Capacity for both models can be up to 120 litres/min, when fed by 30 litres/min hydraulic oil. For instance if operated by a PS 15 with extra large hydraulic pump
The Auger pump is mounted on single preheater. The pump is driven by a hydraulic motor. The pump and pivoted material pipe is heated by heat transmission oil, which is circulated by a hydraulically driven pump. The capacity is 45 litres/min, when operated by a PS 15, provided with extra large hydraulic pump.
The gear pump SP 2000 is especially used for jobs with big lifting height, or long material pipe. The gear pump is operated by a hydraulic motor. Pump and material pipes are heated by heat transmission oil, which is circulated by a hydraulically driven pump. Max capacity is 120 L/min when fed with 30 L/min. hydraulic oil flow. For the SP 2000 a motor driven PTO can be used for driving a hydraulic pump. An electrically operated control valve govern the gear pump speed. With this arrangement remote operation of the pump system can easily be performed.
