Advancements in thermal technology introduce high-temperature vacuum insulation (up to 1000°C)
For years, cryogenic systems have benefitted enormously from vacuum insulation. According to NASA, “Cryogenic thermal insulation systems that incorporate a vacuum environment can provide the lowest possible heat transfer.” But what about high-temperature applications? Could vacuum insulation be an effective high-temperature insulation material?
Cryogenic thermal insulation systems that incorporate a vacuum environment can provide the lowest possible heat transfer.
Traditionally, vacuum insulation has not been used at high temperatures due to a variety of issues. However, advancements in thermal technology are opening new doors for the incorporation of this highly effective insulation material in non-cryogenic systems.
Insulon® Technology represents advancements in high-temperature vacuum insulation. Based on proprietary vacuum technology, Insulon® vacuum insulation is effective in applications up to 1000°C (1832°F).
Why is vacuum insulation considered the best known insulator?
Vacuums serve as high-performance thermal barriers to prevent heat transfer due to thermal conduction and convection.
With its complete lack of atoms, a vacuum is often considered to be the best known insulator.
While all vacuum insulation reduces heat transfer due to convection and conduction, the addition of multi-layer insulation (MLI) can reduce radiation heat transfer as well. This creates Vacuum Super Insulation for even greater thermal performance. Just like all Insulon® products, our Vacuum Super Insulation with proprietary MLI can perform in high-temperature environments up to 1000°C (1832°F).
In addition to high-temperature capabilities, Insulon® vacuum insulation offers an ultra-thin profile, long-term reliability, and low maintenance performance.
Ultra-thin vacuum insulation
The overall wall thickness of Insulon® vacuum insulation can be as low as 0.25mm. Insulon® vacuum insulation is so thin, it can be used to insulate hypodermic needles. Insulon® is suitable for surgical-grade and medical-grade insulation applications.
Reliable insulation performance
Most vacuum insulation systems require pump downs in order to maintain high vacuum levels. Insulon® vacuum spaces are hermetic, gas-tight enclosures that maintain high-quality vacuums for extended service life without pump-down maintenance. In fact, Insulon® vacuum parts don’t even have pump-down ports.
Low maintenance materials
With a vast number of insulation materials available, selecting the right one can be a challenging process. Many materials provide adequate insulation but come with other problems. Materials may require tedious installation processes that include wrapping, spraying, or clamping. Some materials may be unsightly or have an odor. Wear and tear can introduce problems such as delamination or corrosion under insulation. Maintenance may include time-consuming removal, inspection, and reinstallation.
Insulon® provides a solution to many of the problems posed by traditional insulation materials. Insulon® parts are low maintenance, reliable, and aesthetically pleasing. Stainless steel design resists corrosion. Installation does not require any accessories such as clamps or tape. With Insulon®, the insulation is built into the metal component, which is visible to the naked eye. Parts can be easily inspected without the need for insulation removal and reinstallation.
