Product Range
One family of fluids, engineered for every process temperature.
Every grade below is built around the same principle: protect the metals in the loop while carrying heat efficiently, for long enough that you stop thinking about the fluid at all. Each card shows its operating range and typical application first talk to our technical team for a system-specific recommendation.
Modified-diol family
ET-4 Series
Our core secondary refrigerant and heat-transfer fluid family. Formulated from a modified diol base with a corrosion inhibitor, biostat, solubiliser and water-stabiliser package, ET-4 fluids replace inhibited ethylene-glycol and carry heat in both directions across a single closed loop.
The workhorse grade, with broad compatibility across stainless steel, carbon steel and copper.
The same modified-diol chemistry as ET-4, reformulated to hold up under sustained high-temperature operation.
Manufactured with food-grade raw materials and very low acute oral toxicity.
Formulated without inorganic salts for low electrical conductivity. Compatible with stainless steel, carbon steel, copper and aluminium.
The lowest-conductivity grade in the range, with no inorganic salts.
Organic acid salt family
ET-8 Series
A potassium-formate, water-based heat-transfer fluid delivering stronger thermal performance than glycol or calcium chloride, with no flash point and no flammability classification.
An alternative to calcium chloride, trichloroethylene, methylene chloride and silicone fluids.
The same organic acid-salt chemistry as ET-8, reformulated for high-temperature systems.
The same organic acid-salt chemistry as ET-8, reformulated for systems containing aluminium components.
Fluorinated dielectric family
ET-14 Series
A colourless, non-conductive, non-flammable dielectric fluid family for direct-immersion cooling and very-low-temperature process duty, spanning seven grades from −110°C up to +135°C.
Electrically non-conductive with no flash point. Enables PUE below 1.1 in immersion-cooled deployments.
High-temperature family
ET-16C & ET-17
For processes that run hot rather than cold: ET-16C is a single-fluid hydrocarbon heat carrier stable up to +340°C, and ET-17 is a hydrocarbon dielectric fluid for data-centre immersion duty.
A modified synthetic hydrocarbon heat-transfer fluid with good thermal stability and minimal metal corrosion.
Non-corrosive to electronic components, with good resistance to acid and sludge formation over time. Pour point −40 to −50°C and closed-cup flash point 107–138°C, grade-dependent — full operating range to be confirmed with our technical team for your specific duty.
