Fin Type

Natural Fin Type

Exposure to the elements is part of everyday life for a radiator system, so correct selection of our materials of manufacture is critical.

Air Radiators cores feature high purity brass and copper alloys in the manufacture of the heat transfer surface to ensure high thermal performance and suitable life. Copper and brass fin offers a high level of corrosion resistance under most circumstances, providing long operational life and reliability for your machine or process.

Heavy gauge and appropriately tempered materials provide the highest levels of durability from mechanical damage, with capacity to withstand pressure washouts and the rigors of everyday operation.

Solder Coated (SC)

Solder Coated is a highly durable heat transfer surface for corrosive environments.

Conventional brass tube/copper fin radiators provide an efficient and economical heat transfer surface, however the relatively light gauge copper fin strip in a raw state may be susceptible to corrosive attack, in environments such as:

  • Coastal areas
  • Heavy industrial locations, eg. refineries, smelters
  • Large cities, particularly on top of high rise buildings
  • Mine sites - phosphate, coal and salt
  • Exposure to bore or ground water

Solder Coated cores are made with solder pre-coated fins and conventional solder pre-coated brass tube. Following assembly, the core is oven baked to ensure mechanical tube/fin bond and complete solder coating of the heat transfer surface.

Samples of Solder Coated cores and many standard core types were salt spray tested by Aerospace Technologies Australia Ltd, to International Standard ASTM-B117. After 2000 hours of testing, the Solder Coated core was ranked with the highest resistance to salt corrosion.

Deep Hem

Air Radiators offers the Deep Hem feature on all plate fin radiator cores. Deep Hem is a system where by the faces of the core are folded back past the first row of tubes. This process significantly increases rigidity of both core faces, and extends service life, particularly in applications where the core surfaces are regularly impacted by foreign objects or high pressure power-wash.

Steel Insert Hem

Off Highway applications can mean harsh, dusty environments. High velocity dust blown by the cooling fan acts like a sandblaster, wearing the core away, causing breakdowns. Remoteness and high ambient conditions often call for around the clock operation with little opportunity for downtime.

Air Radiators offers stainless steel hemmed fin product that provides a high strength edge on the face of the core, resisting abrasion and grit blasting by the high velocity cooling airflow directed onto the cooling group. We bond the edge hem to the radiator during our manufacturing process, ensuring the high duty hem is there for life.

Cores last longer, machines have more uptime and you make more money.
