In order to solve the heat loss problem occurred at VIT coupling or coupling + donut combination, Shengji developed a new type vacuum coupling. The heat conductivity coefficient is 60% of conventional coupling. It is new design and patent vacuum insulated couplings.It has two layers and vacuum annular structure. In vacuum annular, there are warping of insulated materials to guarantee the insulation performance.
Without insulated sleeve, all tools and pumps can be loaded easily.
