STABILISATION INSERTS


LOKPREP APPLICATION


LOKPREP LT & HT

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.

POSSIBILITY A Move the nozzle 360° around the tube to distribute the LOKPREP evenly.

POSSIBILITY B Rotate the moistened tube through 360° inside the joint.

POSSIBILITY C Rotate the joint through 360° around the end of the tube.

ANAEROBIC SEALANT FOR BRASS LOKRING CONNECTORS (UP TO 30°C)

Specially developed for use with LOKRING brass connectors.

Can be used in ambient temperatures up to 30°C (86°F).

Must be used for all LOKRING assemblies.

Compensates for any unevenness in the tube surface.

Ensures that every LOKRING connection is hermetically sealed.

IMPORTANT:

HEADERS AND STOPPERS


The variety of reducing connectors, reducing T-connectors and also reducing elbow connectors needed for combining all the different tube

diameters which are nowadays being used in air conditioning systems is constantly growing. In order to stay flexible installers needed to build

a huge stock of all the different connectors. With the new NRA reducing adaptors VULKAN Lokring has launched the solution for this problem.

You just need the standard connectors, T-connectors and elbow connectors and make the reduction by connecting the correct NRA adaptor.

Thus you will always have the correct connection available directly on-site.

EXAMPLE OF USE INCORRECT*

USE OF T-CONNECTORS AND REDUCING ADAPTORS WITH STABILISATION INSERTS

TRACE GAS LEAK DETECTION

HYDROGEN MOLECULES HAVE THE LOWEST ATOMIC MASS

LEAKAGE FORMING GAS 95/5 ESCAPES

PROBE WITH DUAL SENSORS

FOR LEAK DETECTION, the empty air conditioning system is charged with forming

gas 95/5 consisting of 95 percent nitrogen and 5 percent hydrogen. Forming gas

95/5 is non-flammable, non-toxic, non-corrosive and not harmful to the environ-

ment. Hydrogen molecules have the smallest atomic mass of all the elements and

can escape due to even the smallest leak. With the aid of hydrogen leak detectors

LOKTRACER TLD.500 and LOKTRACER TLD.1000, very small leakages can there-

fore be detected. The leak detectors react almost exclusively to hydrogen. There

are therefore hardly any cross sensitivities

THE LEAK DETECTION TECHNOLOGY DEVELOPED FOR THE INDUSTRY IS PERFECTLY TAILORED TO SERVICING APPLICATIONS, AND THEREFORE GUARANTEES LEGALLY COMPLIANT, FAST, RELIABLE AND SIMPLE LEAK DETECTION.

02 | LOKRING & LOKCLIP

THE PATENTED LOKRING® TUBE CONNECTION SYSTEM PROVIDES AN INNOVATIVE SYSTEM OF SOLDER-FREE TUBE CONNECTIONS FOR EVERY REPAIR SITUATION IN VEHICLE AIR CONDITIONING SYSTEMS.

THE BENEFITS

For universal use, independent of the vehicle type and model year

No waiting for expensive original spare parts

No welding, soldering or thread cutting necessary

In many cases, the faulty line may not even have to be removed

For more than 30 years tried-and-trusted by OEMs

In compliance with EU directive 2006/40/EG

LOKRING tube connections can be made without a great deal of force being

necessary, using simple hand assembly tools. LOKRING ensures an absolutely

clean, permanent and purely mechanical tube connection with long-term hermetic

air-tightness. This is confirmed by the special TÜV test and approval. All this

makes LOKRING tube connections one of the most economical and reliable

methods of connecting refrigerant tubes.

LOKRING® & LOKCLIP

Type-examination tested

WITH LOKRING & LOKCLIP YOU CAN REPAIR:

Straight tubes and elbows

Hoses

Hose-to-Tube connections

Pressure switch connections

Service ports

Threaded connections

LOKRING & LOKCLIP | 03

REPAIR THE LEAK!


THE TYPICAL LOKRING union joint consists of two LOKRINGs and one tubular joint for the acceptance of the two tube ends. Thanks to the conical inner contour of the LOKRING and the special outer contour of the joint, the diameter of the connection is reduced during assembly to such an extent that the joint and the 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 LOKRINGs acting in the opposite direction to the tube-joint connection.




Admissible refrigerants: Suitable for R134a and HFO-1234y.Other refrigerants on request.


MATERIAL COMBINATIONS

Tube diameter range:8 to 19 mm (5/16" to 3/4")

LOKCLIP TECHNOLOGY provides you with a simple and low-cost alternative to pressed and screwed connections for hoses. LOKCLIPs can be used to set up both hose-to-hose and hose-to-tube connections for all conceivable repair situations. The system,

comprising stainless steel clips, clip position holder and contoured joint practically excludes application mistakes during assembly. Alongside the important SAE J2064, LOKCLIPs meet all the required standards.

02 | THE BEST CONNECTION

THE BEST CONNECTIONTHE 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!

REFRIGERATORS AND FREEZERS. This is where the use of LOKRING has been proven

a billion times over for the last 40 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.

AUTOMOTIVE AIR-CONDITIONING. LOKRING has been a supplier of tube connections

for the initial fitting of air-conditioning components to leading suppliers in the auto-

motive industry for many years. The LOKRING SINGLE RING is being used for the

series manufacture of evaporators and heat exchangers made of aluminium.

You can find more information on pages 08 – 27.

You can find more information on pages 30 – 31.

THE BEST CONNECTION | 03

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 on page 33.

HOW CAN WE CONNECT YOU? 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?

BUS AIR-CONDITIONING. 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.

04 | FUNCTIONAL PRINCIPAL

FUNCTIONAL PRINCIPALTHANKS 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 pretension, 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 | 05

THE BENEFITS

LOKRING IS FASTER

A LOKRING joint needs just 10 seconds irrespective of

the material combination. And the more LOKRINGs that

are applied, the more significant becomes the time

advantage.


As LOKRING can join any tube materials with the same

level of quality, you can switch the components and tubes

of the cycle system to the most feasible and most cost

effective material – regardless of brazing standards.

FORWARD – LOOKING SOLUTIONS

As it is the preferred material for brazing, Cu material

is extensively used in refrigerant cycle systems.

However, Cu is heavy and expensive. For example, in

the highly innovative automotive industry, all refrigerant

lines are Al material. By “joining” LOKRING you can

finally consider the new possibilities!

LOKRING is the preferred alternative to brazing as it is

more cost effective, delivers better quality with less

failure and leak rates, as well as being faster.

Furthermore, it provides an excellent opportunity to

switch tubes and components of the cycle system

to cost saving materials (e.g. aluminium).

LOKRING IS BETTER

€€€LOKRING directly saves the costs for silver solder and

highly trained operators. Meanwhile, LOKRING indirectly

reduces potential brazing cost implications that might

occur through leaks, corrosion, harmful fumes, damage,

burns or tube preparations. LOKRING may even reduce

the number of joints needed and the consumption of

expensive Cu components.

LOKRING IS COST EFFECTIVE

A correctly made LOKRING joint ensures both a zero

failure rate and zero leak rate in both plant and field. In

addition, the LOKRING joint is very clean both inside and

outside and there is no possibility of damage and burns

occurring from brazing inside a cabinet. Finally, it ensures

that there is no corrosion on grinded St tubes and no

hazardous brazing fumes.

06 | PRICE HISTORY AND TREND OF RAW MATERIALS

TREND OF RAW MATERIALSCOPPER, 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 2017, as well as anticipated price trends up to 2020, on the assumption

that there will be consistency in the historical rate of price increases.

COPPER VERSUS ALUMINIUM AND STEEL. As copper material is used for many components and refrigerant lines in the

refrigeration industry, it plays a significant role in the cost of production. Since 2005, the price of copper material has

increased with an average yearly increase of 7%. On top, the price has been fluctuating greatly which makes cost planning

very difficult. The prices for aluminium and steel on the other hand have not been fluctuating so much. The price of

aluminium material has increased with an average yearly increase of 2.5% and the price of steel material has increased with

an average yearly increase of 1.7%.

For obvious reasons, the automotive industry – which is particularly known for high cost pressure – is using only aluminium

material, which when taking into consideration the light weight (1/3 the weight of steel), is the most economical material

for components and refrigerant lines. However, with aluminium comes the problem of brazing. With LOKRING, this is not a

problem as it can easily join tubes of any material. Therefore, LOKRING can help you to reduce your production costs!

PRICE HISTORY AND TREND OF RAW MATERIALS | 07

SILVER BRAZING. The cost of silver brazing is dependent on the following factors: silver price, gram (g) of silver solder per

joint and the percentage (%) of silver in the solder. The following chart shows the exemplary costs of one brazed joint of

minimum quality (0.6 g / 20%) and one of maximum quality (1.0 g / 30%) and the corresponding anticipated cost trends

to 2020, once again assuming the silver price increases consistency in line with historical trends.

LOKRING VERSUS SILVER BRAZING: Silver brazing has become increasingly expensive. Furthermore the silver price has

been fluctuating greatly which makes the cost planning for brazing very difficult. The exposure to the anticipated future

price increases of silver represents a significant risk in terms of any cost planning. Meanwhile, the price for LOKRING

SINGLE RING is not only cost effective but should also prove to be constant in the long term!

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 tube sealings). 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 advantages

of choosing LOKRING SINGLE RING solutions rather than opting for brazing each section and individual application.

12 | EVAPORATOR SECTION

EVAPORATOR SECTIONEVAPORATOR SECTION Generally, the evaporator is made of aluminium and as it is not possible to braze Al to Cu in the

plant, the evaporator supplier has to supply the evaporator with Al to Cu connectors at suction, as well as on the capillary

side. The manufacturer is then brazing the Cu suction tube and Cu capillary tube to the Al to Cu connectors inside the

cabinet in the plant. Therefore, the conventional way results in a total of 4 joints: 2 Al to Cu connectors made by the eva-

porator supplier and 2 Cu to Cu joints brazed by the manufacturer. However, by choosing LOKRING you can reduce the

total number of joints to 2 Al to Cu joints or even 2 Al to Al joints and also experience plenty of associated advantages!

16 | CONDENSER SECTION

CONDENSER SECTIONCONDENSER SECTION. This model of refrigerator has two condensers – a back plate condenser and an additional

side plate condenser. Therefore, in total, the condenser section has 3 critical joints. One St to St joint from the

back plate condenser to the liquid line and a second St to St joint from the side plate condenser to the back plate

condenser. The third joint from the hot gas line to the side plate condenser is a Cu to St or St to St joint. All 3 joints

are brazed with expensive silver solder, which necessitates the preparation of the St tube and protection of the

connection point against corrosion, and they all have a maximum leak rate.

CONDENSER SECTION | 19

For brazing these joints, silver solder of 30%

is typically used.

Due to critical joint, generally speaking, the most

skilled operator is used to braze these joints.

Maximum rate of leakages both in the plant

and in the field.

The potential to overlook faults at the solder

seam of the St tubes is quite high.

If tubes with a different kind of St material are

preheated for brazing, the “weaker” tube gets

brittle, resulting in damage.

To avoid corrosion after removing the zinc

coating, the connection points have to be painted

or protected by a shrinking hose.

The joint looks very unclean after brazing

and scale removal is required.

Protective equipment against harmful

brazing fumes is necessary.

PROBLEMS OF BRAZING

As LOKRING is a cold connection you do not

face any problems induced by brazing a

St to St or Cu to St joint.

The switch from brazing to LOKRING is easy

and can be implemented immediately as

no major changes are required.


Joining both St to St and St to Cu with LOKRING

is a reliable, fast and easy operation that takes

just 10 seconds.


No need for expensive silver solder.

No skilled operators required.

No extra costs through leaks in plant or after

sales service costs.

No protective equipment required against

harmful brazing fumes.

COSTS€€€

No leakages either in field or in production.

No hazardous brazing fumes.

QUALITY

No additional operation of applying paint or using

shrinking hose for protection against corrosion.

No scale removal of the soiled joint after brazing

is required.

TIME

FORWARD-LOOKING SOLUTION

Using LOKRING on the condenser(s) can reduce

material costs as the wall thickness of tubes

can be reduced to 0.3 mm.

As the weight of Al is 1/3rd of St and the price is

nearly double, costs can be reduced by using LOKRING

and switching the condenser(s) from St to Al.

DRYER SECTION. The dryer has 2 critical joints. One is the dryer to the capillary tube joint (Cu to Cu) which,

when brazing, is most critical for choking or leakages, and this is worsened by the high rate of leakages

from the field which result in extra costs in terms of after sales servicing. The second joint is the liquid line to

the dryer joint (St to Cu), which is brazed with silver solder. A third application on the dryer is the LOKRING

stopper for sealing off the charging tube.

FORWARD-LOOKING SOLUTIONS

As the LOKRING technology can easily join Al to Al or St to Al it is possible to switch the material of the capillary tube and dryer from Cu to Al.

€€€

For proper brazing the joint needs to be

preheated. As the capillary is very soft

and its wall thickness is just 0.5 mm,

the ID of the capillary may collapse and

choke while preheating.

Preheating and brazing this joint requires

the most skilled of operators.

Without an even preheating the capillary

suffers micro porosity in the brazing

flux, which results in very minute leaks

occurring in the field.

No need for silver solder.

No high extra costs through blockages,

leaks in the plant or after sales service.

PROBLEMS OF BRAZING

Neither leakages in the field nor

in production.

No choking of the capillary tube by high

temperature of brazing with silver solder.


No harmful brazing fumes.

09. Suction line > Compressor

10. Compressor > Hot gas line

COMPRESSOR SECTION. There are 3 joints and 1 sealing of the charging tube on the compressor. All 3 joints on our

(frost free) model are Cu to Cu joints. Brazing Cu to Cu joints is less critical and less expensive than joints comprising

different tube materials. However, what appears to be an advantage for brazing comes at the cost of a high consumption

of expensive Cu tube on the suction line and hot gas line. And if this is not enough, the brazing fumes are unhealthy and

brazing becomes a risk in cases where hydrocarbons are used. Furthermore, the compressor is the most visible part of

the cycle system and therefore brazing looks unprofessional, dirty and is often perceived as a low quality solution.

Initial investment for ultrasonic welding is high.

Jaws for ultrasonic welding are expensive and

have to be changed periodically.

When jaws are worn-out or Cu tube quality is not

perfect it causes leakages at the sealing point.

LOKPREP FUNCTION

Metal tubes can have production-related longitudinal grooves or

surface scratches. However, these faults can be compensated for

by moistening the surfaces of the tube ends that are to be

connected with LOKPREP fluid prior to assembly. Thanks to its

capillary characteristic, it automatically covers the surfaces of the

inserted tubes and flows into microscopic cavities and fills these

out completely.

Rather than being an adhesive, LOKPREP is in fact an anaerobic

sealant that hardens under oxygen exclusion and when in contact

with free metal ions. At the end of the hardening process the

LOKPREP sealant retains a permanently elastic structure. This

means that it does not get brittle and therefore compensates for

material-specific deformations.

There are different types of LOKPREP in order to achieve an optimal

effect that is primarily dependent on the materials used, the

installation conditions and the ambient temperature. The choice of

the LOKPREPs to be used is defined by VULKAN Lokring after the

customer specifies the application.

EXTERNAL TUBELOKRING

LOKPREP

LOKPREP

LOKPREP was developed especially for LOKRING assembly

and must always be used wherever LOKRINGs are to be

fitted. LOKPREP is used to provide additional safety in

LOKRING connection technology and it compensates for

possible unevenness in the tube surface, such as longitudi-

nal grooves or surface porosity. Consequently, it guarantees

that every LOKRING connection is hermetically sealed.

OPERATIONAL INSTRUCTION

After finishing the charging, simply enter the

tube into the recess of tool jaws and pinch

off the tube by closing the sliding valve situ-

ated at the end of the tool. You can release

the tool by opening the sliding valve.

Add LOKPREP (approximately 3 mm from

the tube end). Put on the LOKRING stopper

with a slight motion of rotation to ensure a

better distribution of the LOKPREP.

Insert the stopper which is placed on the

tube in the tool jaws to ensure that the

tube is fully inserted into the stopper. By

operating the sliding valve, the LOKRING is

pressed over the collet and seals the tube.

BRASS / ALUMINIUM CONNECTORSTHE TYPICAL LOKRING union joint consists of two LOKRINGs and one tubular joint for the acceptance of the two tube

ends. Thanks to the conical inner contour of the LOKRING and the special outer contour of the joint, the diameter of the

connection is reduced during assembly to such an extent that the joint and the 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 LOKRINGs acting in the opposite direction to the tube-joint connection.
