About
Beyond Gravity’s COOLCAT line of multi-layered vacuum thermal insulation products is designed specifically for cryogenic applications. We offer standard and tailor-made insulation solutions, made with aluminized polyester foils interleaved with polyester spacer materials or aluminum foils interleaved with glass spacer materials. We also supply welding protection materials and tapes.
To precisely cut polyester superinsulation blankets to shape, we use numerically controlled (NC) laser cutting machines. This process assembles the multi-layered package around its cutting edges, using bridges of molten polyester to hold the edges together. Laser cut edges are open for edge pumping. Our NC laser cutting machines can accommodate a maximum width of 2.7 m and length of 3.0 m.
Key features include high-quality polyester film, 6 or 12 micrometres thick, double-sided aluminized at minimum 40 nm; reflector foils separated with pure polyester spacer material; 10 layers of foil and 10 layers of spacer combined as a semi-finished insulation lay-up ready for cutting; insulation perforated for complete evacuation of the vacuum chamber; long-term stable performance with no degradation due to spacer material; and very high reproducibility of performance in serial production.
Applications include helium liquefiers, superconducting magnets, liquid gas tanks and infrastructure, liquid nitrogen, liquid helium and liquid hydrogen systems, MRI/NMR, accelerators, stationary and mobile tanks and transfer lines.
