About Mayekawa

MAYEKAWA is a world–leading supplier of industrial cooling and freezing systems, refrigeration compressors and heat pumps.

Environmental sustainability is the focus of Mayekawa’s commercial activities. The company has long pursued natural refrigerant technologies and energy-efficiency solutions. The application of natural refrigerants and thermal-engineering solutions that use less energy aim to support sustainable development, save ozone layer depletion and stop global warming.

Natural refrigerants have a lower GWP (Global Warming Potential) than HFCs, as well as zero ODP (Ozone-Depletion Potential), making them environmentally friendly refrigerants.

These refrigerants have much more features to enhance energy efficiency drastically as compared to conventional utilities according to applications and temperature ranges.

Mayekawa has a history in developing and manufacturing products and systems utilizing these natural refrigerants and refers to this approach as the NATURAL FIVE, five natural refrigerants; ammonia (NH3), carbon dioxide (CO2), water (H2O), hydrocarbons (HC) and air. These natural refrigerants are applied in heating, drying, hot water supply, air conditioning, cooling, chilling and freezing over a multitude of temperatures from 200℃(392F) to -100℃ (-148F).

To enhance the sustainability in social systems, so many things which Mayekawa can do are yet to be done as countermeasures for climate change and energy-saving and we will make more efforts to promote such activities.
