Thermal Transfer

What Are Heat Transfer Fluids?

Heat transfer fluids are specialised solvents designed to efficiently conduct and transfer thermal energy in precision industrial processes. Unlike water-based coolants, these engineered fluids offer superior thermal stability, chemical inertness, and compatibility with sensitive electronic components — making them essential for applications where temperature control directly affects product quality and reliability.

In electronics manufacturing and testing, heat transfer fluids maintain precise temperature conditions during burn-in testing, thermal shock cycling, and component cooling. Their low surface tension allows complete wetting of complex component geometries, ensuring uniform heat distribution across every surface.

Techspray Precision-V Solvent Range

The Techspray Precision-V range is a comprehensive family of heat transfer fluids formulated for demanding thermal management applications. Each variant is engineered with specific boiling points, viscosities, and thermal conductivity profiles to match precise process requirements.

Key properties of the Precision-V range include excellent dielectric strength for safe use with energised electronics, low global warming potential (GWP) formulations that meet evolving environmental regulations, broad material compatibility with metals, plastics, and elastomers, and non-flammable chemistry that enhances workplace safety. Several Precision-V solvents serve as direct drop-in replacements for discontinued products such as 3M™ Novec™ 7100 and 7200 series fluids.
