Frequently Asked Questions
Here are some common questions about ZeroMax™.
ZeroMax™ is an access port system that eliminates the need for process tubes while maintaining hermetic metal-to-metal sealing without elastomer seals. It enables near-zero-emission processing and service operations while remaining compatible with both current and next-generation refrigerants.
Its quick-connect processing tools incorporate self-sealing valves that preserve vacuum or refrigerant charge upon disconnection. Recovery-port versions also allow refrigerant to be routed directly to a recovery system, preventing any release to the atmosphere.
Yes. ZeroMax™ provides safe processing and circuit access for systems using A2L and A3 flammable refrigerants by eliminating process tubes and leak-prone piercing valves.
