To help the heat exchange, the two tubes can be soldered together as in the case of tube-on-tube copper heat exchangers; or the capillary tube can be passed through the suction tube as in case of Al-Cu mono-tube heat exchangers.
In KONVEYOR, both of the two types and also some special ones for special freezers (like combi, frost-free, or home air conditioner) are manufactured in large quantities.
Copper, capillary and (partially) aluminum tubes supplied from major European manufacturers, are cut to lengths and brought together by using special machines.
Aluminum-copper connections of the mono-tube suction tubes are performed mainly by reliable and competitive ultrasonic soldering method with more than 15 years of KONVEYOR experience in this application.
- All heat exchangers are tested against leak by special machinery or apparatus.
- The capillary tubes of all heat exchangers are tested by flowmeters as 100%.
- All heat exchangers meet the internal cleanliness criteria defined by the related standards.
- As all open ends tapped by plastic caps, they are packed on Euro pallets properly for long distance deliveries
