The cold storage material moves back and forth inside the cylinder, causing the refrigerant gas to expand adiabatically and generate cold.
The 77K GM Refrigeration Machine CH-110 is a mechanical refrigeration unit that generates cold by having the heat storage material move back and forth inside a cylinder, causing the refrigerant gas to undergo adiabatic expansion. The method used to move the heat storage material back and forth in the GM refrigeration machine, manufactured by Sumitomo Heavy Industries, utilizes a crank mechanism to convert the motor's rotational motion into reciprocating motion. Additionally, innovations in the two-stage heat storage material seal make this refrigeration unit the world's first refrigeration machine that does not have restrictions on the installation direction of the 4K refrigeration unit.

Company information
Nagase Techno Engineering Co., Ltd. (abbreviated as NTE) was established in 1983 as a machinery service company of Nagase & Co., Ltd. and changed its name to the current one in 2009. It is the core company for equipment development and maintenance services within the Nagase Group and is expanding its business globally. Our company operates three main businesses: the sale and maintenance of low-temperature and vacuum-related equipment used in the semiconductor and medical fields, a Chemical Management System (CMS) for the recycling of chemicals used in the manufacturing of semiconductors and LCD panels, and a surface defect inspection device (SCANTEC) for inspecting optical and functional films and sheets. We aim to strengthen our global engineering services by leveraging the Nagase Group's network that spans overseas. Additionally, as a new challenge, we will utilize our high engineering capabilities in the agricultural sector to benefit customers outside of domestic manufacturing.
