COLD & CRYOGENIC INSULATION
Cold and cryogenic insulation includes specialized methods applied to pipelines, tanks, and equipment operating between –196°C and +40°C in LNG, oxygen, nitrogen, hydrogen, CO₂, frozen food, cold storage, and ammonia systems.
These applications require exceptional workmanship; even minor penetrations compromising the vapor barrier can lead to severe icing, affecting product quality, system safety, and energy consumption.
