Copper fin coils are also special coils that Grand provide. These coils don’t have a bi-metallic bond usually found on standard coils and have a copper wavy fin pattern bonded to the copper tubes.
These coils are very reliable heat exchangers as they are required and can operate for air conditioners in harsh coastal areas and other highly corrosive surroundings because the coils have higher coastal corrosion durability. The coils match this type of environment because the bi-metallic construction is not present, and copper has a natural protective film and a mono-metal bond attaching the tube and fin. They have superb thermal conductivity, resistance and strength compared to aluminium.

Extruded fin tube is rolled as an integrity with no thermal contact resistance, high intensity, featured in thermal shock and mechanical shock resistance. Heat exchangers assembled with this kind of fin tube (extruded fin type) is much better than the one equipped with string fin tubes or hectically wound fin tubes (L/LL/KL type fin).
Extruded Finned Tubes, also known as “Integral Finned Tubes”. Integral finned tubes are manufactured by rolling process on tubes. During finning operation, the inside diameter of the tubes is reduced and helical fins are rolled on the tube wall. The tubes material can be Copper Alloy, Brass Alloys, Copper Nickel Alloy, Titanium Alloy, Stainless Steel, Duplex Stainless Steel etc. The pressure required to extrude fins from the aluminum sleeve creates an excellent “pressure bond” between the two materials.
Copper and aluminum com-posited fin tubes are rolled from a muff copper tube, advantaged in tight link, small thermal resistance, good heat transfer efficiency, small flow loss and strong corrosion resistance. When working in long time under heating and cooling conditions, they are durable and not easy to deform.
The integral extruded fin tubes is smooth on surface and easy to clean. When wet cooling in heating and air conditioning project, it is easy to remove the condensation water on the outer surface of the fin, and it is not easy to dust and scale in the heating and other heat exchange.

Longitudinal finned tubes are produced by welding the fins with resistance along the length of the tube. The fins first form a u-shaped channel, allowing each of the u-shaped legs to form a fin. The channel is cut to the appropriate length and then welded into place along the length of the tube and resistance. The channels are a pair of welded, polar opposites, so the number of fins specified must be a multiple of four.
For a given tube or tube size, the desired heat transfer surface area per tube unit length can be obtained by specifying the appropriate fin height and number of fins. The maximum number of fins depends on the outer diameter of the tube – the larger OD tube can accommodate more fins.
