ALR Range


300 W to 2.3 kW - Fan Coil Radiators - Water to Air


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

The ALR range of fan coil radiators offer an ultra clean, stainless steel coolant circuit suitable for high purity deionised water.

Our fan coil radiators 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.
