Heat exchangers

for gear, power steering and engine oil cooling systems

consist mainly of finned tubes in copper or aluminium alloys. Similar to thread rolling, the fins are rolled out from the wall of the plain tube. Finned tube heat exchangers retain their form under extreme conditions whilst being sufficiently malleable to allow bending to almost any shape. These characteristics combined with high performance allow the size of the heat exchangers to be kept to a minimum.

These heat exchangers are mainly used as air-oil coolers, whereby the cooling air flows around the fins. However, it is also possible to place a coiled heat exchanger into an oil bath (gear or engine sump), whereby the lost heat is channelled via the cooling water.

Coiled heat exchangers are only made to order and subject to a minimum order requirement. We would be pleased to assist you with the design and construction of your heat exchanger.

for pre-warming of engine oil in arctic conditions

are mainly coiled heat exchangers consisting of finned copper tubes. Similar to thread rolling, the fins are rolled out from the wall of the plain tube.

Finned tube heat exchangers retain their form under extreme conditions, as for example commercial vehicles are being subjected to, whilst being sufficiently malleable to allow bending to almost any shape. These characteristics combined with high performance allow the size of the heat exchangers to be kept to a minimum, for example in an engine sump.

The excellent thermal conductivity of copper and the extended surface area of finned copper tubes allow the heat to be transferred from a hot water-glycol mixture to an engine sump in an amazingly short time. This facilitates starting of the engine in cold conditions.

Coiled heat exchangers are only made to order and subject to a minimum order requirement. We would be pleased to assist you with the design and construction of your heat exchanger.
