Vacuum insulation for high temperature fluid transfer up to 815C (1500F)
Insulating high temperature fluid systems has never been simple. After installing the process piping, a secondary insulation material needs to be wrapped around the pipe and clamped, taped, or otherwise fixed into place. Once installed, the insulation requires periodic inspection and maintenance to manage moisture, corrosion, and other issues.
Now, high temperature insulated tubing is available in the form of Insulon® Vacuum Jacketed Hose for fluid transfer systems up to 815 Celsius (1500 Fahrenheit). A groundbreaking solution for high temperature applications, Insulon® hose delivers ultra-high performance thermal insulation in a corrosion-resistant, stainless steel package.
The vacuum barrier is pre-installed into the double-walled hose, arriving at your facility with the thermal insulation already in place. Rather than installing transfer hoses and insulation materials separately, the pre-insulated Insulon® hose can be installed in one easy step.

Thermal Insulation Performance
The charts below illustrate empirical test data collected while transferring hot air though Insulon® Vacuum Jacketed Hose. The charts include the inlet media, outlet media, and midpoint external surface temperatures at steady state. The hoses used for these tests were 1/2″ ID and 6′ Length. Ambient temperature was 23°C.

Maximum Allowable Working Pressure (MAWP) by Temperature — Insulon® Hose
Insulon® hose is available in two pressure level options: low pressure (LP) and high pressure (HP). For high temperature applications, pressure rating decreases as the fluid temperature increases. Contact us for help selecting the right pressure rating →

Option to sleeve over fluoropolymer tubing
For applications that require smooth internal bore or non-metallic wetted surfaces, sleeve Insulon® Hose over fluoropolymer (PTFE, PFA, FEP) tubing. Ideal for deposition/carrier gases and other controlled environments in sensitive manufacturing settings for semiconductor and other industries.
Note: Sleeving Insulon® Hose over fluoropolymer tubing affects both the operating temperature range and maximum allowable working pressure (MAWP) of the assembly.
