The RAC Engineer’s Guide to Low GWP Refrigerants 28 When engineers are servicing refrigeration systems there is the potential for refrigerant to spray out from the service port. This can result in refrigerant loss and the risk of refrigerant burn for the engineer. Designed with the user in mind, JAVAC’s safe seal charging hoses are the only hoses on the market that feature a special valve that eliminates this risk. Secure fitting The ideal addition to an engineer’s toolkit, the R32 ready hoses’ One-Touch design ensures user safety by securing the fitting connection before starting refrigerant flow. Engineers simply turn the single knob to tighten the fitting onto the service port. After the valve is fully connected, turning the knob pushes the internal core depressor to activate refrigerant flow from the system. Only once fully secured and sealed can the refrigerant run from the system into the hose. Crucially, thanks to the One-Touch design, refrigerant cannot spray out when connecting the hose to the system. Safety is improved further with the swivel design. The innovative swivel sleeve ensures that the fitting will not come loose – even if the hose is moved or accidentally tugged on. It also allows free rotational movement, without the fitting becoming loose. Traditionally hoses without a sleeve, run the risk that a fitting connection will loosen when a hose is moved, resulting in unwanted leaks. Hose disconnection is just as safe and easy as connection. Turning the knob backseats the core depressor – closing the Schrader valve and stopping the flow of refrigerant. The fitting is then unscrewed from the port by continuing to turn the same knob. Stopping the flow of refrigerant while the fitting is still securely connected ensures no loss of gas. Once the fitting is safely disconnected, refrigerant inside the hose will remain safely sealed inside, unable to escape to air and can be recovered at a later time. Quality and efficiency With years of engineering and servicing experience JAVAC endeavours to deliver the best and most complete range of tools in the industry. JAVAC’s safe seal charging hoses make the engineers’ job easier and safer while minimising the environmental impact of refrigerant gas. Innovative, high quality and efficient to use, the hoses are simple to transport and use, while offering JAVAC’s market- leading performance. Scott Davies, UK Sales Director for JAVAC UK, explains why their unique Safe Seal charging hoses are the safest way to attach refrigerant hoses to a service port. Safe and Secure
