Refrigeration systems

Choose from a range of refrigeration systems according to your temperature needs and facility size. The freezing and refrigeration technologies that Mayekawa has developed through a long history of designing, constructing, and servicing refrigeration plants support the reliability and trustworthiness the company's products have earned. Additionally, in order to contribute to the prevention of global warming and ozone layer protection, we are increasing our product lineup by continually developing extremely safe and efficient refrigeration systems that use natural refrigerants.
Since air acts as the refrigerant, not an HFC, there is no refrigerant-induced impact on the global environment. Furthermore, in the ultra-low temperature range from -50 to -100℃ (-58 to -148℉), it is possible to reduce CO2 emissions and achieve energy savings of up to 50 percent compared to conventional vapor pressure refrigeration systems.

  • NH3/CO2 cascade refrigeration system
    An environmentally friendly cascade refrigeration system that uses ammonia as a refrigerant on the higher-temperature side and CO2 on the lower-temperature side. As only CO2 is supplied as the secondary refrigerant, the risks associated with ammonia are minimized. This product is suited for use in situations where low temperatures are needed, such as freezers that have internal temperatures of -40℃ (-40℉) or lower. By controlling the number of refrigeration compressors on the high-and low-temperature sides, it is possible to operate the system in line with the required load.
