Mitsubishi Heavy Industries Air-Conditioning & Refrigeration Corporation (MHI-AC&R), a part of the Mitsubishi Heavy Industries Group, has introduced the event of N-Bleath, a compact brine chiller using nitrogen as a pure refrigerant. The product, which is about to hit the market in April 2027, goals to deal with environmental issues with its zero ozone depletion potential (ODP) and international warming potential (GWP).
The N-Bleath chiller is designed to handle ultra-low temperature ranges, from -40°C to -100°C, making it appropriate for various functions in sectors reminiscent of medical, pharmaceutical, chemical, and semiconductor industries. The unit’s compact and modular design affords space-saving advantages and improved backup capabilities, lowering set up constraints and gear downtime dangers.
Key to its innovation is the combination of a newly developed compact electrical turbo from Mitsubishi Heavy Industries Engine & Turbocharger, Ltd. (MHIET). This part permits the chiller to realize excessive effectivity and miniaturization. The electrical turbo combines a high-performance impeller with an ultra-high velocity motor, leveraging aerodynamic efficiency and high-speed rotation applied sciences.
By utilizing nitrogen as a refrigerant, the N-Bleath chiller avoids the usage of PFAS, lowering environmental impacts and well being dangers. Additionally, the unit isn’t topic to laws reminiscent of Japan’s High Pressure Gas Safety Act, simplifying upkeep and operation.
MHIET’s electrical turbo is designed to be oil-free, eliminating the necessity for periodic lubricating oil adjustments and additional lowering upkeep necessities. The turbo’s superior thermal insulation permits it to chill to temperatures beneath -100°C, enhancing its efficiency in ultra-low temperature functions.
MHI Group plans to advertise the adoption of cooling programs that use PFAS-free pure refrigerants with zero ODP and GWP. By supplying compact electrical turbos with excessive energy-saving efficiency, the corporate goals to contribute to the discount of environmental impacts within the ultra-low temperature market.
