Applications
Cryopreservation for Sample Storage
For use with cryogenic freezers to maintain the ultra-low temperatures required to preserve the integrity and efficacy of samples including live tissues and cells.
Liquid and Cryo-Compressed Hydrogen
Minimize boil-off material losses with ultra-high performance vacuum jacketed hoses for LH2. Benefits include compact design and low non-volatile residue (NVR) on surfaces.
Food and Beverage Industry
Insulon vacuum jacketed hoses improve rapid freezing, chilling, and cryogenic grinding processes used to preserve perishable food and beverage products.
Industrial Cryogenic Gas Supply
Insulon hoses facilitate the safe and efficient transfer of cryogenic fluids for a range of applications including electronics manufacturing and healthcare.

Vacuum insulation for low temperature fluid transfer
Insulon hoses excel when handling extremely cold or cryogenic temperatures. The key lies in their double-walled design which offers unmatched thermal insulation and energy efficiency. By incorporating advanced vacuum technology, the double-walled hose creates a vacuum-sealed space between the inner and outer layers. The vacuum barrier effectively minimizes heat transfer and reduces cryogenic fluid boil-off losses.
Proprietary Technology
Insulon hoses are different from other vacuum jacketed hoses. They are manufactured with a proprietary process that has a range of benefits:
Low maintenance: Other vacuum jacketed hoses may require pump-down maintenance; Insulon hoses do not. Concept Group’s proprietary manufacturing process results in a hyper-deep vacuum space that delivers reliable, long term performance.
Smaller outer diameter: For a given inner diameter hose size, Insulon hoses typically have smaller outer diameters than other vacuum jacketed hoses. This makes Insulon hoses ideal for compact applications.
Compatible with hydrogen: Hydrogen is different from other cryogens and has its own unique material requirements. Insulon vacuum jacketed hoses are compatible with liquid and cryo-compressed hydrogen transfer.

This chart illustrates the temperature difference between the process media (LN2, -196°C) and the external surface of an Insulon vacuum jacketed hose. The temperature difference at steady state was over 205°C (369°F). Ambient temperature was 23°C.
This analysis was conducted with a 1/2″ ID x 6′ L Insulon vacuum jacketed hose, low pressure (LP). High pressure hoses also available. Option to include multi-layer insulation (MLI) for “super” insulation performance.
