FasTest Introduces New CoreMax SV™ Service Valve

Single Port Service Valve Improves Manufacturing Processes for Split System Air Conditioner Manufacturers

Minneapolis, MN—January 18, 2024—FasTest, Inc. introduces the latest CoreMax® innovation for the HVAC-R market: a service valve specifically designed for split system air conditioner and heat pump units.

The CoreMax SV™ is engineered with a single port and the advantages of FasTest’s revolutionary CoreMax technology to replace common leak-prone service valves. FasTest's service valve reduces process connector tooling and labor costs by up to 67%, maximizing manufacturing cost reduction. The CoreMax SV also improves field installation and servicing, providing up to five times faster flow when evacuating or charging refrigerants compared to Schrader type valves. The CoreMax SV is fully compatible with conventional service tools, and the 30° valve design increases SEER rating and field processing ergonomics.

“We engineered the CoreMax SV to provide manufacturers with an alternative to outdated service valves in use today and to reduce our customers’ manufacturing, processing, and servicing costs.” said Thomas Braun, HVACR Product Manager. “The CoreMax SV design is also safer, eliminating the potential for refrigerant discharge in the event of an accidental connector “blow-off”… especially with flammable A2L refrigerants. In addition, it provides greater flow for refrigerant filling and eliminates the need for specialized process connectors and tools in the field. Split system air conditioner and heat pump manufacturers, along with service technicians will all benefit from upgrading to FasTest’s CoreMax SV technology.

FasTest will be introducing this new CoreMax SV technology at the 2024 AHR Expo – Booth #N1831.
