We are the only independent manufacturer and supplier of mixed gas refrigerants which we market under the Cascade brand. A significant proportion of our business activities are concerned with the remanufacturing of Cryocooler systems to comply with EU 842/2006 (F-Gas Regulations). Cascade UL refrigerants have 70% lower global warming potential, than competitors.  All new water vapour cryo-pumps for the vacuum sector use technology conceived and developed and patented by Stratox.
