THE BEST CONNECTION THE LOKRING SINGLE RING TECHNOLOGY is a method for connecting metallic refrigerant lines without brazing so that they are permanent and hermetically sealed. For this purpose, VULKAN Lokring constructs customised LOKRING tube connections for any application based on the tube materials, dimensions and tolerances and the associated assembly tools. The primary area of application is the manufacture of the refrigerant circuit in the series production of refrigerators and freezers. There are other applications for the manufacture of evaporators for automotive air-conditioning...

Would you like to cut costs, improve the quality or solve a problem while manufacturing a refrigerant circuit? Would you like to dispense with brazing at a specific connection or dispense with it completely? Please contact VULKAN Lokring and we will find a solution for your application. You will find contact information on pages 54 – 55. HEAT EXCHANGERS / HEAT PUMPS. Situations may arise while installing heat exchangers into a refrigerant circuit, resulting from construction-related or material-related constraints that make brazing impossible or uneconomical. An example of the solution for...

FUNCTIONAL PRINCIPAL THANKS TO THE CONICAL INNER CONTOUR of the LOKRING, the diameter of the outer tube is reduced during assembly to such an extent that the inner tube and the outer tube create a hermetically sealed metal-to-metal connection. The lifetime gas-tightness of the fitted connection is ensured by the state of permanent elastic pre-tension, which is produced by the radial forces of the LOKRING acting in the opposite direction to the connection between the outer tube and the inner tube.

THE BENEFITS LOKRING IS BETTER LOKRING IS COST EFFECTIVE LOKRING is the preferred alternative to brazing as it is more cost effective, delivers better quality with less LOKRING directly saves the costs for silver solder and highly trained operators. Meanwhile, LOKRING indirectly failure and leak rates, as well as being faster. Further- reduces potential brazing cost implications that might more, it provides an excellent opportunity to switch tubes occur through leaks, corrosion, harmful fumes, damage, and components of the cycle system to cost saving mate- burns or tube preparations....

06 | PRICE HISTORY AND TREND OF RAW MATERIALS TREND OF RAW MATERIALS COPPER, ALUMINIUM AND STEEL RAW MATERIAL. The applied raw materials for components and tubes in a refrigerant cycle system are an essential input factor behind the cost of production. The following price chart shows the price of raw materials from 2005 to December of 2014, as well as anticipated price trends up to 2018, on the assumption that there will be consistency in the historical rate of price increases.

PRICE HISTORY AND TREND OF RAW MATERIALS | 07 SILVER SOLDERING. The cost of silver soldering is dependent on the following factors: silver price, gram (g) of silver solder per joint and the percentage (%) of silver in the soldering flux. The following chart shows the exemplary costs of one soldered joint of minimum quality (0.6 g/ 20 %) and one of maximum quality (1.0 g/ 30 %) and the corresponding anticipated cost trends to 2018, once again assuming the silver price increases consistency in line with historical trends.

REFRIGERATOR APPLICATIONS

REFRIGERATORS AND FREEZERS THE CYCLE SYSTEM OF A REFRIGERATOR can be segmented into four sections: evaporator, condenser, dryer and compressor. The segmented cycle system below is a no frost model comprising two condensers and it is displaying the maximum quantity of 12 LOKRING SINGLE RING applications (10 tube joinings and 2 pinch-off pinchings). As the cycle system is the heart of every refrigerator, these 12 points are essential as regards operability, reliability and thus the overall success of a refrigerator. In the following chapters of this catalogue we will discuss and outline the...
