Air Blast Coolers - Liquid-Air Units » ALR Range

0.3 to 2.3kW

Description

Fan Coil Heat Exchanger - Tube-fin heat exchanger/fan assembly for removing process heat from circulating coolant.

The ALR range of air to liquid heat exchangers offers an ultra clean, stainless steel coolant circuit suitable for high purity deionised water.

Our tube-fin heat exchangers consist of stainless steel tubes expanded into copper fins and provide flexibility to meet a wide range of applications including water-cooled medical and industrial laser equipment. In addition to the standard modules, a computer aided design facility provides the ability to meet specific performance and dimensional requirements.
