JAVAC launch new PVR manifold

Javac have launched a new manifold for evacuating and pressure testing via the single manifold unit to speed up testing and commissioning of AC and refrigeration systems.

Called PVR, it’s designed to speed the process up via two gauges - one for vacuum and one for nitrogen pressure. It also features a two-valve manifold, one for nitrogen pressure isolation, and the other for vacuum.

The manifold block is without a sight glass to prevent glass blow out. While the hoses can easily be switched from pressure to the vacuum side safely, with the vacuum gauge fitted with a pressure relief valve in-case of accidental over pressure.

The PVR replaces the needs for two separate gauges sets with separate hoses, which traditionally provides no way to control or shut off the pressure/vacuum safely away from the nitrogen bottle regulator. Using separate gauges also leaves no way to safely vent the nitrogen and secure the gauges to anything, leaving them vulnerable. The PVR supports both these procedures in one.

Scott Davies of  JAVAC who developed the manifold system said: “This is a unique patent pending idea that will improve speed, efficiency and safety when testing systems and had all the built in safety features. It should assist all engineers in the day to day work.”
