With the WEH® TW111 Service Connector for filling and evacuating refrigerants when servicing industrial refrigeration and air conditioning equipment, WEH has been supplying its customers with a real climate protector – for over twenty years now.
Way back when the WEH® TW111 was launched on he market twenty years ago, its benefits to the environment were certified by an expert opinion by the Forschungszentrum für Kältetechnik und Wärmepumpen (the German centre for refrigeration technologies and heat pumps).
The shut-off valve integrated into the connectors reduces emissions of refrigerant by up to 99%. When the connector is released, only the small amount of residues left between the check device in the Schrader valve (on the air conditioning system side of the connection) and the shut-off valve (on the connector side) can escape. The residues left behind in the filling hose are not lost. At the same time, the system protects the user’s hands from painful freezing and burns.
But the WEH® Service Connector also provides many other additional benefits.
Fitted with the WEH® Jaw Locking Mechanism, the product closes around the “Schrader valve” in seconds in conformity with the SAE J513 standard.
There is no need to laboriously screw the connector on and off. Simply place the connector over the Schrader valve and push the sliding sleeve forwards. A safe and pressure-tight connection is thus established, and the filling operation can begin. The TW111 also impresses with its compact outer diameter of 25 mm, which allows easy connection even if the available space is limited.
