Helium Charged - Vacuum Test

LEAK TESTING ON CAR AIR CONDITIONER EVAPORATOR

Double Chamber machine for Evaporators with central sliding cart for loading/unloading. Principle of measurement: Global test with mass-spectrometer.

BENEFITS
  • Dedicated pumping system for the analysis - Total flow
  • Pumping system placed on a cart for easy maintenance
  • Dedicated Electric and Pneumatic cabinet
  • Ventilation and Sound proofing of the pumping system
  • Totally customizable HMI interface
DESCRIPTION

The machine provides two vacuum chambers, with manual opening and closing, assembled on a welded and painted steel frame with movable panels. The chambers work alternatively: when one chamber is closed and it’s running the test cycle, the other chamber is open for loading/unloading. The vacuum pumping system is placed behind the chambers. The cabinets containing the electric switchboard and the analysis systems are fixed to the frame, while the pneumatic boards for the distribution of the process gas are fixed to the vacuum chambers. Both chambers are opened automatically towards the centre of the machine, so that the loading/unloading position is the same for both of them and it is protected by optical safety barriers. HMI is made by a touch-screen colour monitor and two remote control boxes (one for each chamber) with the push-buttons and light signals for the operator. The equipment provides separate outlet ports for helium and air discharge and it is suitable to be connected to a helium recovery system.
