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

Entgasungsstation T-EVAC
Offline degassing station Basic
T-EVAC

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

  1. Air and humidity, which affect the quality, is removed from the resin
  2. Filling via IBC, tank container or, if applicable, existing tank farm for material supply
  3. The degassed material can be conveyed into intermediate containers or directly into possible dosing systems
Entgasungsstation T-EVAC - IBC
Offline degassing station
T-EVAC

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

  1. Air humidity, which affect the quality, is removed from the resin
  2. Filling via IBC with material buffer or, if applicable, existing tank farm
  3. Degassed material is temporarily stored in the IBCs as a supply and can therefore be made available to several dosing systems
  4. No process interruption, as degassed material is always available and ready for use
Entgasungsstation T-EVAC - Tank
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
NODOPUR mit T-EVAC
NODOPUR Direct Infusion

Volume-flow controlled dosing and mixing system of the NODOPUR series with inline degassing module T-EVAC

  1. Material is degassed on the machine before dosing in the vacuum container
  2. Application: Turbine blade production by direct infusion
  3. Mobile due to coupling device
  4. PVC dust protection (enclosure)
