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 systems, for heat exchangers in refrigeration and air-conditioning technology (e.g. manufacture of heat pumps) or with the serial installation of refrigeration and air-conditioning technology (e.g. air-conditioning for buses). Whether it is a matter of optimising costs, improving quality or solving a problem – LOKRING SINGLE RING is the answer!
Areas of Applications
REFRIGERATORS AND FREEZERS
This is where the use of VULKAN Lokring has been proven a billion times over for the last 36 years. Nonetheless, it is in this segment that many LOKRING SINGLE RINGs are being constructed at present for new applications so that an increasing number of brazed connections are being replaced by LOKRING.
LOKRING has been a supplier of tube connections for the initial fitting of air-conditioning components to leading suppliers in the automotive industry for many years. The LOKRING SINGLE RING is being used for the series manufacture of evaporators and heat exchangers made of aluminium.
Aluminium lines are increasingly being used in the installation of bus air-conditioning systems due to cost and weight considerations. This is facilitated by the use of LOKRING SINGLE RING as an efficient and reliable alternative to brazing.
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 such a Cu-Ti tube connection in a heat pump using LOKRING SINGLE RING is illustrated here.
