Extruded profiles made out of aluminium, rubber or thermoplastics find application in the air conditioning and the refrigeration industries. A vast range of products starting from gaskets to even condenser frames all are using extruded profiles in one way or the other. The following section discusses these popular usages.

Use of Aluminium in Extruded Airconditioning Industry
Extruded aluminum profiles are increasingly developed and selected as the perfect material for air-conditioning systems involving residential or commercial premises. Aluminum micro channel or (Micro-Flow) tubing as it is called is providing necessary attributes for achieving the desired internal and external performance objectives. The things that are aiding this switchover to extruded aluminium profile are excellent resistance of aluminium to corrosion, ability to be extruded into complex shapes, thermal conductivity, light weight and good strength. The aluminum brazed condenser used in the air-conditioning systems has brought in some significant improvements. Now increasingly accessories in support of this item like connectors, brackets, support channels will also be made out of extruded aluminium profiles to derive the innate benefits of aluminium. The image of an brazen condenser that is all aluminum is shown here. It has been made as a flat slab, and subsequently bent to conform to the specifications, with regard to cabinet. Some of the advantages of this product include the following :

• Increasing throughputs
• A decrease in the need of costly complex components
• Increased durability
• Decrease in the use of ozone depleting gases.

Use of Aluminium in Extrusion in Refrigeration
These days consumers demands products that has a good visual appeal. Refrigerators that has great commercial looks along with space are what the consumers are now demanding. Constant innovation has led to the launch of a stainless steel built-in refrigerator. But wait a while, what might look like stainless steel to the eye may in fact not be so. The refrigerators are now using stainless steel metal panels that are actually framed by aluminum extrusions, which are made to appear like stainless steel. The aluminum extrusions goes through the process of brushing and anodizing with unique stainless color. Application of aluminum extrusion for this application offers the following advantages:

• Lightweight
• Strong material
• Complex shapes
• Lower cost

Extruded Rubber Profiles for Refrigerators
Extruded rubber Gaskets are commonly used in the refrigerators. They are perfect for both commercial or residential purposes. Gaskets can be used either for Chest-coolers/freezers which are generally non-magnetic or Visi coolers/ Refrigerators that are generally magnetic. (A refrigerator Door Seal) Sealing between a door and the refrigerator is easily achieved by employing a tubular extruded profile in vulcanised rubber. It can be injection spliced at the joint and properly compressed using a lever tumbler lock.
Sponge profiles and tubings are used in the Air conditioners. These extruded profiles are made from fine quality rubber that retains their smoothness.

Extruded Plastic Profiles for Refrigerators
Coming to the extruded profile range of plastics there is an amazing range available that is used in different segment of the refrigerators. Some of the application can be broadly according to exterior applications or interior applications.

Interior applications
Here the extruded profiles used can range from refrigerator door, inner liners and door liners.

Application	Product
Refrigerator - interior application	Co extruded polystyrene is used as inner and door liner that gives matt or gloss surface
Refrigerator - interior application	Co extruded ABS is used for inner and door liners

Exterior applications

Application	Product
Refrigerator - external application	Coextruded ABS/PMMA along with a high gloss surface suitable for refrigerator external parts like doors and housings.
Refrigerator - external application	Co extruded ABS/PMMA with a matt surface in colours that are metallic.
