Thermal Vacuum Chamber miniWRK PREMIUM

The Mini-WRK (“WeltRaumKammer”, German for Space Chamber), also known as µWRK, is used for thermal vacuum testing of samples and smaller parts, including the testing of component functionality like heaters, actuators, or release mechanisms. Its main difference to our larger test facilities is the extended temperature range of [+350;-190] °C under vacuum or [+300;-180] °C under inert gas atmosphere. For short time, the upper service temperature may be increased to 400 °C.

Additionally, the test facility may be equipped with an induction heating system, allowing testing of small samples up to 1,350 °C.

The µWRK is made of a barrel-type vacuum chamber with an inner diameter of 500 mm and a depth of 320 mm. The chamber is entirely made of stainless steel. A water-cooled shroud insert allows testing in an extended temperature range.

  • Process plate dimensions: 340x300 mm²
  • Maximum temperature: 300 °C continuous, up to 350 °C short-term
  • Minimum temperature -190 °C under vacuum, ~-180 °C under nitrogen gas
  • Heating/Cooling Range up to 10 K/min
  • Atmosphere: Vacuum 1e-6 mbar, non corrosive gas (N2, CO2, Ar,...) up to ambient pressure

For special applications a inductive heating system or a radiation heating system can be installed.
