Overview |
The
amount of heat within a chemical, biological, electrical,
or manufacturing system commonly determines the efficiency
of processes and reactions within the system. Controlling
the amount and flow of heat in these systems is equivalent
to controlling the process and is often a critical factor
in its success or failure. Thermal fluids are liquids
specifically designed to conduct and store heat. They
are commonly used instead of thermal gases or coatings
since they offer greater design flexibility, stability,
and operational temperature ranges. A wide variety of
thermal fluids are available to system engineers including
water-based, mineral-based, and synthetic thermal fluids.
Water has traditionally
been used as a thermal fluid due to its availability,
environmental neutrality, and adequate thermal characteristics,
but over time, mineral-based thermal fluids have gained
popularity. Mineral-based fluids are less corrosive,
operate at wider temperature ranges (allowing heating
and cooling with the same liquid), and exhibit better
thermal storage and conductivity characteristics. However,
despite the attractive thermal and operational characteristics
of mineral-based thermal fluids, disadvantages include
increased flammability, toxicity to the environment,
and health risk to workers in extreme conditions. Synthetic
thermal fluids were invented to offer the benefits of
mineral-based fluids without their detriments, and a
wide range of synthetic thermal fluids is available.
NanoTechLabs synthetic
thermal fluids are built upon an ionic liquid platform
and offer several advantages over previous synthetics,
mineral-based, and water-based fluids. NanoTechLabs’
thermal fluids are
- Environmentally
friendly - NanoTechLabs' thermal fluids emit no
toxic fumes in high temperatures, and possibilities
exist to create these from renewable ingredients
- Inflammable
- Non-volatile
through negligible vapor pressure - NanoTechLabs'
thermal fluids will not evaporate in low pressure
environments and they do not boil. This alleviates
dangers commonly associated with steam systems.
- Capable of
operating at wider temperatureranges than competitors
(-60 C to 400 C)
- Capable of
being tuned for optimal performance at given operating
temperatures
