Cryogenic cooler test bench
Fast & Safe Cryocooler testing
for cryocooler performance validation (heat capacity map) and/or reliability test
Key Features:
- Monitoring and Control software with recording and display of measured parameters (standard is 2 temperatures, power applied on cold stages (heat load) and vacuum)
- Default accomodation: cold head vacuum flange ISO160, cold finger length 380mm
- smaller/larger diameter and length can be adapted with custom interface plates to be designed by Callisto
- 220V and 380V mains capacity (mono/tri)
- Water cooling for the cryogenic compressor
- Custom test profiles on demand
