Easy Access for Small Systems using Processing "Stub" Tubes

The new ZeroMax™ Access Port and Tooling system was designed to address the shortcomings of process stub tubes used by OEM manufacturers of PTAC, Commercial Refrigerators and other equipment using ”Hermitcally sealed compressors”. ZeroMax provides advantages over process tubes, including:

•    Provides easy, repeatable & hermetically sealed system access to add/reclaim refrigerant.
•    Eliminates potential connector blow-off & dangerous discharge when charging refrigerant, protecting operators & the environment.
•    Eliminates wasted copper tube ends and the emission to the environment of refrigerant contained in them.

Processing PTAC/PTHP, Commercial Refrigerators, etc. using traditional process “stub” tubes is cumbersome, can release refrigerant to atmosphere, and requires time consuming manual “Pinch-N-Braze” sealing or expensive automatic ultrasonic welders to create a permanent seal upon processing completion. Moreover, gaining system access for rework or post-production service is a time consuming and often unreliable process, e.g. refrigerant “Piercing Saddle Valves” that can result in leakage of refrigerant to the environment.

With FasTest’s ZeroMax™ Access Port system, manufacturers can eliminate the process stub tube altogether while maintaining full flow for the fastest possible evacuation. In addition, should system access be required for rework, field service or end-of-life refrigerant recovery, the ZeroMax™ system provides easy access and a reliable hermetic seal, eliminating the need for leak-prone, expensive saddle valves. 

Also, as new, flammable, “A2L” & “A3” refrigerants are introduced, manufacturers want to eliminate refrigerant emissions to the atmosphere.  ZeroMax can provide true “Zero Emission Processing” capability resulting in no refrigerant escaping to the environment!
