8 08 VULKAN LOKRING the LOKRING-service-concept repairs quickly, hermetic, versatile range of application The patented LOKRING tube connection system provides an innovative system of solder-free tube connections for every installation situation in refrigeration and air-conditioning technology. LOKRING tube connections can be made without a great deal of force being necessary, using simple hand assembly tools. LOKRING tube connections guarantee an absolutely clean, permanent and purely mechanical tube connection with longterm hermetic air-tightness. This is confirmed by the special TÜV test and approval. All this makes the LOKRING tube connection an economical and reliable method of connecting refrigerant tubes. Among the LOKRING system s many possible applications in household appliance- and refrigeration technology* are for tubes that carry refrigerant in any of the following: DOMESTIC REFRIGERATION APPLIANCES (refrigerators and freezers, wine coolers) PLUG-IN REFRIGERATION UNITS (refrigerated displays, counters, trays and islands) REFRIGERATION UNITS FOR CATERING APPLICATIONS (bar cooling systems, circulation coolers, line cooling devices) * Are you looking for a concept that allows weld-free installation for refrigeration and climatic technology or do you need to repair an auto A/C system?

14 14 VULKAN LOKRING LOKRING ASSEMBLY AND FUNCTIONAL PRINCIPLE one joint, two rings, Four steps - that s all there ist to do. A LOKRING tube connection can be made without a great deal of effort. All you need is a LOKRING tube connection, a hand assembly tool and some LOKPREP. * The ergonomic hand assembly tool works without energy connection, and the patented lever mechanism means extremely little strength is needed for assembly. Compare it with conventional tube connection methods for yourself, and you will see that»lokringing«has the potential to become a classic. Where DIY experts have their»rawl plugs«or»flex«-cut materials, you and your customers could be»lokringing«in all sorts of situations. * The tube reduction or connection is shown disproportionately to clearly illustrate the functional principle. the components of a lokring connection JOINT LOKRINGs lokprep fluid HAND assembly tool

15 VULKAN LOKRING 15 STEP 01 treat the tube ends To make a tube connection, the tube ends must be metallic bright and free of longitudinal grooves caused by production. To remedy this, clean the tube ends with our sandpaper or abrasive mats. STEP 02 apply lokprep Next, moisten the whole tube circumference with LOKPREP by guiding the bottle 360 around the circumference of the tube. Apply the LOKPREP a little away from the cut edge to avoid it getting onto the inside of the tube. Depending on the repair situation, there are several different possibilities of applying LOKPREP over an area - see page 16. STEP 03 insert tubes Then insert the tube ends with the LOKPREP film into the joint. Make sure that the ends of the tubes are inserted to the inner limit of the joint and remain fixed in this position during assembly. STEP 04 press* Finaliy, place the assembly jaws behind the two LOKRINGs and press the two LOKRINGs axially along the joint until these lie flush on the assembly path - and that s it! * There is an example of the pressing procedure with assembly version 00. Assembly instructions for versions 25 and 50 are provided on page 26.

C... move the nozzle 360 around the tube to distribute the LOKPREP evenly. 360 LOKPREP FOR THE TUBE NO WORRIES FOR YOU ALL ROUND. Metal tubes can have longitudinal grooves on the surface from production. These production-related faults can be compensated quite easily by moistening the tube ends to be connected with LOKPREP fluid before assembly. Thanks to its capillary characteristic, it can even flow into microscopic cavities and fill these out completely. LOKPREP is not an adhesive, rather an anaerobic sealant which hardens under oxygen exclusion and in contact with free metal ions. Its elastic structure is permanently retained in a temperature range of 50 to +150 C thus compensating material-specific deformations due to fluctuations in temperature. Since LOKPREP does not contain solvents which have to evaporate during hardening, the finished connection is ready for use shortly after assembly. LOKRING MATERIAL COMBINATIONS * What connections are possible with LOKRINGs? It s very simple: Any metal tube commonly used in refrigeration and climatic technology. The possible combinations are almost limitless. The following can be used a rule of thumb: If at least one of the tubes being connected is made of aluminum, then a LOKRING made of aluminum must also be used. In all other cases, a brass LOKRING is used. In cases of special tube materials, tube coatings, or environmental effects on the material, we ll be happy to provide assistance. * up to 25 bar both standard applications MATERIAL ASSIGNMENT Copper Brass Steel Aluminium

46 46 LOKTRACE LOKtrace FIND THE LEAK! LOKTRACE gas, which is a mixture of nitrogen and hydrogen, is filled into the system for leak detection. LOKTRACE gas is non-flammable, non-toxic, non-corrosive and not harmful to the environment. Hydrogen molecules are the smallest naturally occurring particles and escape from minimum leaks. With the help of the LOKTRACER TLD.500 or LOKTRACER TLD.1000 the tiniest leaks can be detected. The leak detectors react almost exclusively to hydrogen with nearly no cross-sensitivities to other gases. FURTHeR ADvANTAGeS OF THe LOKTRACe SYSTem Finds even the tiniest leaks < 1 g/year Finds every leak even through screed, insulation and foam No cross-sensitivities no false alarm possible through external gases Can be carried out immediately quickly, precisely and economically Absolutely standard conform with EN , EN and global standards compliant THe PeRFeCT SOLUTION LOKTRACe GAS The smallest and most volatile of all gases 14 times lighter than air Non-combustible, non-toxic, colourless and odourless Suitable for pressure test Climate-neutral and inexpensive CONCLUSION: LOKTRACE gas finds every single leak! A LOKTRACe COMPARED TO CONVENTIONAL LEAK DETECTION METHODS Finding leaks through insulation Detecting smaller leaks < 1g/year Compliance with legal regulations Reliability Direct implementation Loktrace UV dye Electronic refrigerant leak detectors Vacuum test Nitrogen and bubble spray
