A Pressure Leak Test or Pressure Decay Leak Test involves pressurizing the coil, component or refrigeration circuit with dry air or nitrogen and monitoring for a pressure drop over a preset time period.

  • It is an automatic pass/fail test suitable for finding gross leaks, in the range of tens of ounces of refrigerant per year.
  • Pressure decay should be used as a preliminary test prior to Helium or Hydrogen Leak Testing.
  • Can replace water bath test but does not provide leak location; a tracer gas leak test such as Helium or Hydrogen/Nitrogen mix is required to locate leaks.

Product Items

VTech PD Series, Pressure Decay Leak Test Instrument

The VTech PD Pressure Decay Leak Test System is a low-cost, bench-top instrument for detecting gross leaks in sealed refrigeration circuits and components.

A Pressure Decay Leak test is highly recommended prior to tracer gas fine leak testing in order to avoid contamination of the test area. In specific applications, where a low leak rate resolution is sufficient, a PD test may be all is required.

The unit is completely automatic. The cycle is selected via the touch screen or optional barcode scanner and started by a convenient foot pedal. An optional two-color stack light indicates the system status.

Additional configurations include the GF10 for tracer gas filling, PD10-HE for PD test with tracer gas filling, and PD10HR for higher leak test resolution.

VTech UNO-H, Pressure Leak Test System

The VTech UNO-H is designed for leak testing of coils and other components as well as refrigeration and A/C sealed systems in a production environment. The equipment is designed for high productivity and can a perform a test cycle in as little as 30 seconds. The VTech UNO-H is fully customizable in terms of test pressure, equipment lay-out and other features in order to meet the most diverse process requirements. For test pressures over 20 bar (290 psig) VTech recommends the use of safety devices (such as protection hoods) for the operator. In a typical cycle, the VTech UNO-H Series performs a Burst Test, Capillary Flow Test (optional) and a Pressure Decay Test.
