Heat Transfer Fluids

Heat transfer fluids, also known as thermal fluids or thermal oils, are specialised products designed to transport thermal energy efficiently and safely in industrial heating and cooling systems. Lubricalia, a leading B2B industrial supplier in Spain since 1994, offers high-quality heat transfer fluids formulated to operate across extreme temperature ranges, from cryogenic applications to processes exceeding 300°C.

Our range of thermal transfer fluids includes highly thermally stable mineral oils for indirect heating systems up to 300°C, synthetic fluids for very high temperature applications, and glycols (ethylene glycol and propylene glycol) for refrigeration systems and climate control circuits requiring antifreeze protection. Each product has been selected for its excellent thermal conductivity, low viscosity at operating temperatures and resistance to oxidative and thermal degradation.

Heat transfer fluids are essential in numerous industrial processes: the chemical and petrochemical industry uses thermal oil heating systems for reactors and distillation columns, the food industry employs glycol circuits for process cooling and cold storage rooms, the pharmaceutical industry requires precise temperature control in its reactors, and concentrated solar power (CSP) installations use synthetic oils as energy storage and transfer media.

Selecting the correct heat transfer fluid is fundamental to the energy efficiency of the installation and process safety. Factors such as operating temperature range, compatibility with installation materials, flash point, toxicity and expected service life must be carefully considered.

The Lubricalia technical team will advise you on the most suitable thermal transfer fluid for your specific application. We offer periodic analysis of the fluid in service to monitor its degradation and plan its replacement preventively. Contact us for your no-obligation quotation.
