TOKYO, November 17, 2021 - Engineers of PHC Corporation, a subsidiary of global healthcare company PHC Holdings Corporation, have received two awards(*1) at the 2021 Kanto Regional Commendation for Invention for the company’s PHCbi-branded ultra-low temperature freezers(*2), which are widely used around the world in the development and storage of COVID-19 vaccines.

As drug development and life sciences research evolve, strict temperature control has become essential for long-term, stable storage of pharmaceuticals and samples. At the same time, demand for energy-saving products is increasing in response to the Sustainable Development Goals (SDGs) related to the environment.

The two award-winning innovations, used in PHCbi-branded ultra-low temperature freezers, address both of these needs. The first, which won the Gunma Prefectural Governor’s Award, is a dual refrigeration inverter that allows ultra-low temperature freezers to maintain internal temperature more accurately and with more stability while achieving the world’s top-class energy saving performance. The second, which won the Invention Encouragement Award, is the freezer door’s latch handle, which is ergonomically designed to keep the outer door of the freezer securely closed while ensuring the door can open and close with minimum force.

The Japan Institute of Invention and Innovation established the Regional Commendation for Invention in 1921 to honor engineers and R&D personnel responsible for outstanding inventions, devices, or designs. The commendations are in regional categories of Hokkaido, Tohoku, Kanto, Chubu, Kinki, Chugoku, Shikoku, and Kyushu. PHC engineers have been honored six years in a row. Previous winning innovations include a prescription management device that includes an unused medication registration function to prevent prescription mistakes, which is used in the electronic medication history system for health insurance pharmacies.
