Heat Transfer Fluids

Technical Information

Whilst water remains the most efficient and cheapest heat transfer fluid, it has several chemical and physical limitations that can affect thermal performance, system reliability and maintenance expenditure. Subsequently, many alternative fluids have been formulated that facilitate effective heat transfer but also improve upon the basic characteristics of water.

Heat Transfer Fluids – Preferred Characteristics

Heat Transfer Fluids, as used in process pipework systems, should be formulated to deliver several functions, including;

The majority of Heat Transfer Fluids used in systems operating below 100OC are mixtures of water and various chemicals.  For systems operating above 100OC it is necessary to consider non-aqueous Heat Transfer Fluids.
