KONVEYOR manufactures copper capillary tubes for refrigeration and air conditioning applications since 2001. The raw material for this production is 6.35-9.52 mm OD DHP grade copper tubes (mother tubes) supplied in LWC coils from suppliers. The mother tube is cold drawn to final size in various drawing steps. The product is for internal consumption mainly, but could also be sold to current customers depending on the request and capacity conditions.

• RANGE: OD = 1.8-4mm, ID = 0.55-1.5mm
• ALLOY: 99.95% min Cu (DHP grade)
• COILS: The product is manufactured in 20-50 kg coils
• CUTTING LENGTH RANGE: min 650mm – max 4000mm
• SPECIFICATION: EN 12735 and EN 12450
• QUALITY: The flow rating is taken under control by regular checks made for each coil being manufactured. The internal cleanliness meets with the DIN 8964 expectation.
• HARDNESS: The product may be “hard, as drawn, F 36”, “semi-hard, around F 26” or in “soft condition under F 20”. The annealing is made in special oven under control atmosphere available internally.
• PACKAGING: Coils are packed in carton boxes and the boxes are placed firm on wooden pallets (weight per pallet: 400-500 kg).

Aluminium Capillary

Aluminium capillary tubes are also available at KONVEYOR. These are thin, precision tubes used in cooling systems, particularly in refrigeration and air conditioning applications. They are known for their narrow diameters and high precision, which makes them ideal for adjusting refrigerant flow rates in these systems.

• Cost advantage
• More lightweight than copper
• Alloy: 3000 Series aluminium
