How to build your Insulon vacuum jacketed hose assembly
Insulon vacuum jacketed hoses are available in a variety of formats to suit your application. Whether you need to safely transfer liquid nitrogen, chiller and heat transfer fluids, steam, or high temperature gases or oils, the Insulon Hose product line can be adjusted to suit your specifications without overengineering. Option to sleeve over PTFE/PFA for corrosive media. Select insulation performance level, pressure rating, and end configurations to suit your specific application.
Applications
Cryogenic fluids
Reduce operating costs with low-maintenance, pump-down-free vacuum jacketed hoses for industrial gas supply, cryo-freezers, and cryogenic hydrogen applications.
Low-temperature chillers
Maximize energy efficiency and minimize condensation with easy-to-install Insulon hoses for chiller supply and return lines. Available in lengths up to 20 meters (66 feet).
Process heating and cooling
Maximize performance for temperature control units (TCUs) used for process heating and cooling in semiconductor, chemistry, research, and laboratory applications.
Exhaust lines
Insulate high temperature exhaust gases with double-walled Insulon Hoses. May also be used to route cables and wires in high temperature environments.
Steam transfer
Improve safety in high temperature, high pressure steam transfer applications in food production and other industries with lightweight, flexible Insulon Hoses.
