Climate pRoteCtion made easy

Using WeH connectors can reduce refrigerant loss by up to 99 % when servicing refrigeration and air conditioning units. The demand for refrigerants continues to grow with the increased use of air conditioning and the demand for chilled drinks, food preservation and industrial chilling. Servicing operations account for almost 16 tonnes of refrigerant per year escaping into the environment as the result of connecting and disconnecting hoses to air conditioning and refrigerating equipment. By using a WEH TW111 quick connector these losses could be reduced by 99 %. The ingenious device incorporates an integrated shut off valve, which contains the gas inside the hose when connecting and disconnecting. This concept has been endorsed by the German research institute FKW in Hannover.

Gain real cost savings by simplifying production processesWEH offers many advanced quick connectors that make connection to fluid lines easier, more reliable and with high integrity sealing. WEH has a suitable quick connector for almost any refrigerant filling application whether for refrigerators, ice machines, air conditioning systems, water coolers or other similar application. The cost savings during production and servicing resulting from easy, fast connection can be considerable.

the unique WeH jaw locking mechanism makes connections in secondsDepending on the inlet WEH connectors are simply placed onto/over or into the inlet. Hard wearing jaws clamp securely and safely. Jaw designs cater for a variety of different connections, including internal and external threads, straight tubes, holes and bores among others. Laborious screwing and unscrewing of hoses is eliminated. A pressure-tight connection for your application is guaranteed using the latest sealing technology.

Features•Pressure-tight connection in seconds•No hand tightening•For connection to ‚Schrader valves‘ acc. to SAE J513 •Small outer diameter•WEH jaw locking mechanism•Robust construction•Minimizes down time•Reduced loss of refrigerant•No frostbitten hands•Also available with 90° media inlet

The WEH TW111 connector is now available with a reduced outside diameter of only 25 mm. It is specifically designed for filling and maintenance of refrigeration and air conditioning systems and plants. Compared to conventional screwed connectors, the escape of refrigerants from the WEH connector during connection and disconnection is reduced by 99 %. Thus saving costs - and far more importantly - our environment. RSI resulting in the inflammation of tendons and abrasion of joints caused by continuous screwing and unscrewing of threaded joints is eliminated. Connection and disconnection is effected by a simple movement of the grip sleeve. The integrated shut-off valve prevents the escape of refrigerant which remains in the filling tube and can then be correctly disposed of. The type TW111 is equipped with a UNF 7/16“-20 thread (equivalent to 1/4“ – SAE tube connection) and is either available for high pressure (red grip sleeve) or for low pressure (blue grip sleeve).

The type TW111 is also available with 90° media inlet.

The WEH product range for the refrigeration and air conditioning industry has been extended by the addition of a further connector for filling R410A refrigerant. The WEH TW111 connector is specifically designed for filling and maintenance of refrigeration and air conditioning systems and plants with ‚Schrader valves‘ which need to be connected and disconnected under pressures up to a maximum of 42 bar. RSI resulting in the inflammation of tendons and abrasion of joints caused by continuous screwing and unscrewing of threaded joints is eliminated. Connection and disconnection is effected by a simple movement of the grip sleeve. The integrated shut-off valve prevents the escape of the R410A refrigerant which remains in the filling tube and can then be correctly disposed of. The type TW111 for R410A is equipped with an UNF 1/2“-20 (equivalent to 3/8“ – SAE tube connection) and is either available for high pressure (red grip sleeve) or for low pressure (blue grip sleeve).

Features•For cylinder valves with RPV•Pressure-tight connection in seconds •No hand tightening•Simplifies the connecting and filling procedure•Suitable for right or left handed operation•Pin within the valve is actuated automatically•RPV is not removed from the valve so it can be used again •WEH jaw locking mechanism

The new WEH type TW920 connector for filling refrigerants overcomes the need to remove the cylinder valve cartridge when filling. The innovative gripper mechanism pulls the valve cartridge pin forward whilst simultaneously providing virtually instant connection to the cylinder valve thread.

Type TW920 is equipped with a safety operating loop.

tW920 with pneumatic linear valveAs an option the WEH type TW920 filling connector is available with an integrated pneumatic linear valve with a sliding sleeve valve for the pilot pressure line (P1) and a venting port (P2). In order to vent back the residual gas, a venting line can also be fitted.

applicationFilling cylinders with refrigerants having valves with external threads and residual pressure valves (RPV).

technical notes

term explanation

Temperature range Standard range: +5 °C up to +80 °CSpecial range: -100 °C up to +200 °C; special applications on request.The temperatures stated as standard cover most common applications. The seal material used has higher orlower temperature limits dependant on material(e.g. NBR -30 °C up to +100 °C, FKM -20 °C up to +200 °C, EPDM -40 °C up to +150 °C).Under such extreme temperature conditions the suitability of WEH products to the application has to be checkedspecifically. If necessary, we can develop special solutions.

Material Parts not in contact with the media may be made of any suitable materials, for example aluminium, brass or stainless steel. Seals, not in contact with the media, are normally NBR.

Pressure -temperature - compensation

For higher temperatures the max. operating pressure needs to be reduced dependant on the application.Possible values therefore are: 50 °C - 5 %, 100 °C - 10 %, 150 °C - 20 %.In case of doubt, please contact us! When using certain materials, for example plastics, the valves need to befurther derated.

Suitability forapplication

When selecting a component, the total system design must be considered to ensure safe, trouble freeperformance. The correct selection of a component, material, temperature, pressure range as well as properinstallation, operation and maintenance are the responsibility of the customer.

definitions

abbreviation explanation

pressure specifications

PN nominal pressure: This is a standardised term

PS

operating pressure: The max. pressure to which the component is subjected (1.25 x PN)

The admissible operating pressure has been determined as follows:100,000 x cycles impacting the component with 125 % of PN. The pressure wave is sinusoidal. The test is performed at a room temperature of approx. 20 °C.

PT test pressure: The pressure to which the component is tested by the manufacturer(„once only“ test, 1.43 – 1.5 x PS)

We cannot guarantee the veracity of the data and the introductions in individual cases due to the large variety of applications for WEH products, and the unknown parameters and conditions of use. We have to refer to the individual order.

The limits of use for pressure, temperature etc. in this catalogue are theoretical data calculated on the basis of tests. Because of different operating conditions we cannot guarantee that the data do accord with the special use of the client.It has to be considered, that in the practical use interactive interferences of data parameters can cause the change of themaximum values. Especially if the operating conditions are extreme, the WEH Company must be consulted before the useof the products. Therefore the requested values should be stated in the individual order, especially for extreme operatingconditions.

Furthermore we point out, that we cannot guarantee for misprints, uncompleted data or misinterpretation. The illustrationof the products is for demonstration only. The exact form and design of the product is only defined by the individual order.The brochure is only an integral part of the contract, if it is agreed expressly. Dimensions and other technical data in thiscatalogue are without obligation.
