Graco HFR Industrial Spraying System for Adhesives
High Pressure Spraying system for 2K adhesives
The HFR is hydraulic, fixed ratio, industrial spraying system which is able to process multiple materials at high flow rates (up to 12L / min) – from rigid and flexible polyurethanes to elastomers and epoxies. Commonly utilized in application involving high throughputs as such in spraying of polyurehtanes and epoxy at different mix ratios.
Equipped with a modular and robust design for extended life span, as a key in the Graco’s technology, and combined with a precise dispensing capability, it furnishes the end user with an advanced and reliable system which reaches a long life span, yet a cost efficient solution
With the Graco’s long lasting HFR Metering System, you enter your material mix ratio and required dosing volume. As the machine dispenses material, it responds automatically with fine tuning adjustments to achieve a steady and repeated material flow, followed by little pressure variations. This on-line ratio control mechanism results in a unusual 1% ratio accuracy, providing you reduced scrap percentage, reduced operator errors and reliable production assurance.
This affordable technology allows you to step a foot inside your target marketplaces, where it may have not been viable before.
The Advanced Display Module is so easy to learn and operate, so you can enjoy the benefits of short set up times and minimal down times .
The control display module enables the following:
• Programmable shot size and seuqnecial program
• Integrated temperature controil
• Immediate reading to of cycle history
• Conter for consumed material and total cycling
