Refrigeration's Largest Access Port for Maximum Flow

Speed up the lengthy evacuation process of large chiller, industrial & commercial packaged refrigeration systems ---  45% or more reduction in evacuation times compared to commonly used Packed Angle and Ball Valves.

The degassing/dehydration evacuation process is a common bottleneck when manufacturing large refrigeration systems, often taking many hours to complete. The use of small, flow-restrictive packed angle and ball valves is a major contributing factor that slows production Takt time during leak test filling, evacuation, and refrigerant charging processes. 

In response, FasTest developed the PortMax Access Port system providing OEM manufacturers and their installation contractors with a high-flow, optimized system of matched components that significantly reduces overall processing time. The result is faster throughput, improved system dehydration and reduce total cost of processing. PortMax is fully compatible with traditional refrigerants as well as next-generation variants.

  • High flow - high conductance design

  • Hermetic seal

  • Compatible with current and Next-Gen refrigerants
