CHALLENGE 

  • Leak test refrigerant-charged control valves using the refrigerant (R410a) as the tracer gas
  • High production demand
  • Prevent valve components and residues from interfering with leak measurement signal
  • Method of calibrating the system

SOLUTION 

  • Dual chamber RGA-based leak test system
  • Batch testing
  • Multiple calibrated leak manifold for system calibration 

SPECIFICATIONS

  • Test Method: RGA refrigerant hard vacuum
  • Leak rate: 1 x 10-7 atmcc/sec R410a
  • Throughput: Approximately 2 valves per minute
