SASPG International

The high vacuum multi-layer insulated tubes employed in this design effectively reduce the heat in-leak and cold loss. Integral bellows are used to compensate the inconformity of shrinkage between the outer and inner tubes. Each tube is equipped with an evacuating connector for re-evacuation of the jacket between the outer and inner tube spaces. This unique and perfect design effectively ensures the integrity of the vacuum in the jacket and offers a long working life.
