WAYEAL Completes Commissioning of SHARP HVAC Helium Leak Testing System

WAYEAL has completed commissioning of a helium leak testing system for Japan’s SHARP. The equipment is ready for shipment and is designed to test air-conditioning indoor-unit evaporators and outdoor-unit condensers.

The project update offers a closer look at the system’s vacuum equipment, chamber surfaces, workpiece connections, and piping layout.

Overall view of WAYEAL's commissioned helium leak testing system for SHARP — Commissioning complete: the SHARP HVAC leak testing system is ready for shipment.

Vacuum Equipment And Chamber Interiors

The system uses vacuum pumps from Germany’s Leybold. Inside the vacuum chambers, mirror-polished stainless-steel surfaces are designed to minimize residual helium.

Workpiece Connections And Helium Control

Flanged connections and quick-connect fittings inside the chambers support reliable sealing. The workpiece connection lines use a double-wall design with an independently evacuated interspace.

While the workpiece is being evacuated, the space between the pipe walls is evacuated separately. This arrangement helps keep helium permeating through the inner tubing from entering the test chamber.
