Galden HT 110

What is Galden HT 110?

Galden HT 110 is a superior dielectric fluid, highly favored for diverse applications in the vacuum and electronics sectors. With a boiling point of 110°C and excellent thermal management properties for cooling and heat transfer at elevated temperatures, Galden HT 110 is specifically engineered for use in the semiconductor, electronics, and solar energy industries.

Key Features of Galden® HT 110

Galden® HT 110 is a low-boiling perfluoropolyether (PFPE) heat-transfer fluid designed for systems requiring precise temperature control, electrical insulation, chemical inertness and non-flammability. Its nominal boiling point is 110°C.

Galden® HT 110 is particularly suitable for semiconductor process chillers, recirculating temperature-control units, electronic cooling systems, testing equipment and other thermal-exchange systems requiring a balance of low viscosity and reduced evaporation.

Additional Information

Applications of Galden® HT 110

Galden® HT 110 is an inert, dielectric PFPE heat-transfer fluid with a nominal boiling point of 110°C. It occupies the middle of the low-boiling Galden® HT range, balancing low viscosity and cold-temperature circulation with lower volatility than HT 55, HT 70 and HT 80.

1. Semiconductor Process Equipment

Galden® HT 110 is widely suited to temperature-control circuits serving semiconductor fabrication equipment. Typical uses include thermal management for dry etching, chemical vapor deposition, physical vapor deposition, ion implantation and other wafer-processing operations.

Its dielectric properties, chemical inertness, low surface tension and thermal stability support accurate wafer-temperature control in equipment exposed to aggressive process conditions. Stable temperature regulation is important for process repeatability, wafer quality and equipment reliability.

2. Recirculating Chillers and Temperature-Control Units

Galden® HT 110 can be circulated through chillers and temperature-control units connected to semiconductor tools, analytical instruments and precision industrial equipment.

Compared with HT 55–HT 80, HT 110 provides a higher boiling margin and lower evaporation tendency while retaining relatively easy circulation. It is therefore useful for moderate-temperature systems that need better fluid retention than the lowest-boiling HT grades. Syensqo specifically identifies recirculating chillers as an application for Galden® HT fluids.

3. Transformer and Power-Electronics Cooling

Galden® HT 110 can provide heat removal and electrical insulation in compatible transformers, power supplies, converters and other electrical systems.

Galden® PFPE fluids have a typical dielectric strength of approximately 40 kV across a 2.54 mm gap. They are also non-flammable, making them useful where conventional conductive or combustible cooling fluids could introduce additional electrical or fire risks.

4. Supercomputer and Electronic-Equipment Cooling

Galden® PFPE fluids are used for cooling high-density computing and electronic equipment because they combine dielectric behavior, chemical stability and compatibility with many engineering materials.

HT 110 is most appropriate for systems whose required operating-temperature range matches its 110°C boiling point. Depending on the system design, it may be used in an indirect cooling circuit or in direct-contact cooling applications where the fluid remains within controlled operating limits.

5. Chemical and Pharmaceutical Process Temperature Control

Galden® HT 110 can be used in closed heat-transfer circuits serving reactors, process vessels, laboratory equipment and specialized pharmaceutical production systems.

Its chemical inertness helps minimize undesirable reactions with aggressive substances, while its non-flammability can improve process safety compared with combustible hydrocarbon heat-transfer media. Syensqo lists both chemical and pharmaceutical processing among the principal application areas for Galden® HT fluids.

Frequently Asked Questions About Galden® HT 110

1. What is Galden® HT 110 used for?

Galden® HT 110 is primarily used as a dielectric heat-transfer fluid in semiconductor process equipment, recirculating chillers, transformers, computing systems and specialized chemical or pharmaceutical thermal-control circuits.

It is generally selected when the system needs a higher temperature capability and lower evaporation tendency than HT 55–HT 80, without moving to the more viscous high-boiling HT grades.

2. What is the recommended operating temperature of Galden® HT 110?

Galden® HT 110 has a nominal boiling point of 110°C. For an unpressurized single-phase circulation system, Syensqo recommends selecting a fluid whose boiling point is at least 10°C above the maximum operating temperature. This gives HT 110 a general upper guideline of approximately 100°C.

The practical lower operating limit is determined by viscosity, pump capability, flow requirements and system pressure drop—not simply by the fluid’s pour point.

3. Is Galden® HT 110 electrically insulating and non-flammable?

Yes. Galden® PFPE fluids provide a typical dielectric strength of approximately 40 kV at a 2.54 mm gap and a typical volume resistivity of 1.5 × 10¹⁵ Ω·cm.

They have no flash point, fire point or auto-ignition point under standard test conditions. These characteristics support thermal management around sensitive or energized electrical equipment.

4. Can Galden® HT 110 be used for vapor-phase soldering?

Galden® HT 110 may be used for general heat transfer or specially engineered vapor-phase heating, but it should not automatically be treated as a dedicated vapor-phase soldering fluid.

Galden® LS and HS grades are specifically manufactured for vapor-phase soldering and have tightly controlled molecular-weight distributions and vapor-temperature specifications. HT grades are primarily designed as heat-transfer fluids.
