Konveyor Beyaz Esya ve Otomotiv Yan Sanayi Tic. A.S.

In NO FROST type refrigerators, the humidity in the cabinet is collected as ice on special evaporators, and then it is defrosted automatically and discharged to the outside in the form of water at certain intervals. The defrosting is done via various types of heater elements, and the sequence is controlled by special control elements attached to the evaporators.
The NF Evaporators are manufactured in different designs, each having their own advantages and disadvantages. The one manufactured by KONVEYOR is known as the Brazeway type (or inclined type), after the U.S. company who developed it many years ago.

 KONVEYOR specializes in fabricated copper tube parts and assemblies that are used in gas water heater units (domestic boilers).
A gas water heater may be a simple unit generating hot water for a household or it may be a more sophisticated unit called "combi units," generating also hot water for home heating. Within the circuit of the combi unit, more sophticated copper tube assemblies with forged-machined brass bodies or as mounted with special valves are also involved.

 In the production at KONVEYOR, 8x0.70 mm steel tube, 1.3-1.6 mm steel wires are used and the production steps are as follows:

• Cutting the lengths (for the wire and the tube),
• serpentine forming, resistance welding (for the wires to the serpentines) and secondary bending operations are performed by automatic machines.
• The individual shelves and the heat exchanger are brought and hard brazed together to form 2 to 8 shelves units.
• The manufactured units are tested against leaks by Helium Snuffers (1st step test).
• The tested units are zinc plated to 10-12 microns in the fully automatic zinc plating lines.
• After the zinc plating, the 2nd step leak test is applied by Helium Chamber testing systems. The TWO STEP testing principle is unique to KONVEYOR, in order to reach "absolute zero" level leak defects at the assembly lines.
• As the last operation, the Zinc plated units are coated in a protective and food friendly clear lacquer coating (10-12 microns).
• The finished products are packed on euro pallets and shipped to customers.
