Process-integrated vacuum evacuation of air and moisture

Vacuum degassing station T-EVAC

Possible Applications

  • Material preparation for high quality end products
  • Air-free material

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.

Measureably better results with degassed Material

The pictures are taken of two infused composite panels made out of 24 layers of 1200 gsm UD reinforcement infused with epoxy normal to fibre orientation at 30°C.

Material test: Result with degassed synthetic resin and hardener is perfect

Test result without degassing: visible air inclusions (light discoloration)

Sample Projects / Already built systems

Entgasunsstation E-EVAC
Offline degassing station T-EVAC

Central vacuum degassing unit with buffer tank, which fills several dosing systems with degassed material

  1. Air and humidity, which affect the quality, is removed from the resin
  2. Buffer tank stores degassed material and fills the dosing system(s)
  3. No process interruption, as degassed material is always available and ready for use
Inline Entgasung
Inline degassing station T-EVAC

Degassing unit integrated on the dosing system

  1. Air and humidity, which affect the quality, is removed from the resin
  2. Machine filling and material degassing in one step
  3. Machine filling is done during the application process
