Vacuum Degassing Unit T-EVAC

Why degas?

  • Air and moisture that affect quality are removed from the resin
  • improved manufacturing process
  • improved product quality

Vacuum Degassing Unit T-EVAC

We present: the vacuum degassing unit T-EVAC for the process-integrated evacuation of air and moisture from synthetic resins and hardeners before dosing and mixing.

Thus we offer to all users who use the methods of vacuum infusion, wet moulding, resin transfer moulding (RTM) and pultrusion another means of decisively improving both their moulding processes and their product quality. The new degassing unit is suitable for epoxy resin and polyurethane resin degassing. The system solution design comes in two versions: in the form of offline degassing at a central point, from where you can fill the tanks of multiple dosing systems with degassed material. The second version comes as inline degassing, directly integrated into the dosing system and tailored to the process requirements.

The outstanding degassing quality is measurable and has already been verified in test series and applications at our customers.

Measurably better results with degassed material
