GENERAL

The dosing machine cabinet is a compact, self-contained unit that contains all components important for the dosing process:

• precision gear pumps with servo drive for dosing the material components,
• high-pressure water unit for the mixing head rinsing,
• Peltier cooling unit for tempering the mixing head and the recirculation hoses,
• LBM 3 air load measuring and control device,
• compressed air dryer
   

The precision gear pumps are installed in the dosing machine cabinet in a user-friendly manner by a new mounting system. They ensure precise dosing of the material components on their way through the recirculation lines to the mixing head, where they are dynamically mixed in a defined mixing ratio.
The cabinet with lockable hinged doors and a side service door is designed for user-friendly maintenance. Only 2 screws need to be loosened to replace the pumps including the drive train. The side service door provides direct access for removal of the pump heads.

The high-pressure water unit for the mixing head rinsing uses tap water, which is usually discharged into the regular wastewater system after use. This saves disposal costs that would be incurred with conventional solvent-based cleaning (after case-by-case review with local wastewater authorities).

The Peltier cooling unit provides cooling of the mixing head and, if necessary, also of the recirculation hoses and can thus positively influence the reactivity behavior of the 2K material systems.

The LBM 3 air loading measuring device checks the air loading of the A-component to form the desired cell structure of the polyurethane or silicone foam seal.
