4 1 Refrigeration and air conditioning industry 1.1 Introduction» Introduction WEH Your Connection for Refrigerating and Air Conditioning Gain real cost savings by simplifying production processes WEH 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 seconds Depending 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 s, 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. 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. 4 D-2010/07/

38 3 Further information 3.1 Technical appendix» Technical appendix Definitions Abbreviation Pressure specifications PN Explanation Nominal pressure: This is a standardised term Operating pressure: The max. pressure to which the component is subjected (1.25 x PN) PS PT Dimensions L1, L2, L3... Length specification D1, D2, D3... Diameter specification Ports A / B 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. Test pressure: The pressure to which the component is tested by the manufacturer ( once only test, x PS) Medium outlets/inlets P1, P2, P3... Compressed air connections Other DN Nominal bore Technical notes Term Explanation Temperature range Standard range: +5 C up to +80 C Special 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 or lower 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 checked specifically. If necessary, we can develop special solutions. Material Pressure - temperature - compensation Suitability for application 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. 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 be further derated. When selecting a component, the total system design must be considered to ensure safe, trouble free performance. The correct selection of a component, material, temperature, pressure range as well as proper installation, operation and maintenance are the responsibility of the customer. 38 D-2010/07/

39 3.2 Brochure data» Brochure data Maximum care has been taken compiling this catalogue based on many years of experience. However we must point out, that all catalogue data is only valid, if it was expressly confirmed in the individual order. 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 the maximum values. Especially if the operating conditions are extreme, the WEH Company must be consulted before the use of the products. Therefore the requested values should be stated in the individual order, especially for extreme operating conditions. Furthermore we point out, that we cannot guarantee for misprints, uncompleted data or misinterpretation. The illustration of the products is for demonstration only.
