During the installation and servicing of refrigeration and air conditioning technology, the connection of refrigerant pipes is an utterly critical factor if success is to be achieved. Even though soldering unpopular, it was the only method that could be used for this type of work for many decades. Besides the complex and time-consuming assembly work, potential leaks and soiling were also accepted as part of the package.
In other words: ”Does this mean that soldering is a necessary evil”? Perhaps so far it was but this is no longer the case. Thanks to the patented LOKRING® tube connection we can now provide you with a procedure that is as thoroughly reliable as it is exceptionally efficient. The patented LOKRING® tube connection works on the basis of “simple” laws of physics. It consists of two LOKRINGs and one tubular joint which takes the two tube ends. During assembly, the tube ends are inserted into the joint to the inner limit. From there an assembly tool is used to push the two LOKRINGs axially onto the joint. Thanks to the conical inner contour of the LOKRINGs and the special outer and inner contour of the joint, the diameter of the joint is reduced during assembly, in turn enabling the tube and the joint to form a hermetic connection through surface contact.
The lifetime air-tightness of the fitted connection is guaranteed by the state of permanent elastic pre-tension, which is produced by the balance of the radial forces of the LOKRINGs acting in the opposite direction to the tube.
The areas of application for VULKAN LOKRING’s special refrigeration and climatic technology program include all installations of split systems or bond systems, such as air-conditioning systems (split, multi-split, VRF, HVAC), industrial and commercial refrigeration, heat pumps, solar thermal systems, and geothermal energy systems. Compared to the conventional soldered tube connection, the totally clean, efficient and reliable LOKRING® connection delivers many clear advantages: It saves up to 40% of the installation or repair time and helps to avoid all solder-related quality problems. Moreover, it enables installation work to take place not only during business hours but also in areas where there is a fire hazard. The light hand assembly tool ensures easy handling and as a consequence installation can be carried out by non-skilled workers.
The LOKRING® tube connection system has been TÜV approved for all refrigerant systems and heat pumps. The EU standard (EN 378-2), German TÜV (Technical Control Board) and »new« refrigerants such as R 410 A place high demands on tube connections in refrigeration and air-conditioning technology. And for the very first time, each of these requirements can now be met through a solder-free tube connection. Not only did the LOKRING® tube connection pass all of the type-examination tests carried out by the TÜV without exception, the requirements were indeed exceeded in regard to air-tightness, durability and reliability. In addition to the comprehensive TÜV tests, the LOKRING® tube connection was tested to maximum extreme loads in tensile tests. And the result is impressive: The connection is capable of withstanding a pull-out force of up to 40 kN without any problems. This corresponds to a weight of approximately four tonnes, in other words the weight of a fully grown elephant!
