Brine & Water chillers

For both improved efficiency and environmental sustainability, industrial-use refrigeration systems are increasingly using natural refrigerants. At Mayekawa, we design and manufacture a variety of brine chillers built around the MYCOM compressor. And we can design and build units best configured to your specific needs.

0°C + Chilling water

Chiller unit (natural refrigerant)

Chiller unit (natural refrigerant)

This is a chilled water circulation type refrigeration system that creates, supplies, and circulates water with a temperature of 0.5°C (33℉) to the refrigeration process at a food factory. It uses natural and environmentally friendly ammonia as a refrigerant. The amount used to fill the system is kept to a minimum, and the unit is constructed in a manner that prevents leakage outside of the unit or on the chilled water side. A large-bore SUS pipe is used for the chilled water pipe, which makes clogging difficult while also offering excellent cleaning characteristics.

SPECIFICATIONS

  • Cooling capacity: 197kW (56.7TR)
  • Supplies chilled water from 0.5 to 2°C (33 to 36℉)
  • Refrigerant: Ammonia (R717)

WHERE TO USE

  • Poultry processing plants
  • Food processing plants

Standard water-cooled ammonia chiller

mCHILLER FUGU

mCHILLER FUGU

The mCHILLER FUGU is a Mayekawa plug-and-play standard solution with a strong focus on energy consumption and the perfect balance between durability and simplicity. The compact mCHILLER FUGU is designed for easy and simple installation and a long lifespan. It utilizes a natural refrigerant, ammonia, for the highest energy efficiency, and the best sustainability. With an ammonia charge as low as 55 kg (122 lbs), the mCHILLER FUGU achieves a high level of safety.
The mCHILLER FUGU comes with a FAT Report (Factory Acceptance Test) that is performed at our factory. The FAT includes a full load thermal performance test, thermal imaging of key points, and vibration measurements.

Low charge ammonia chiller

Plate type evaporator + Microchannel condenser

Low Charge Ammonia Chiller

Low Charge Ammonia Chiller

Low Charge Ammonia Chiller

The ammonia chiller system with microchannel condenser technology is the result of the extensive experience and technical foundation that characterize Mayekawa's reputation. Microchannel ammonia chiller was developed to meet real market needs, and this unit is different from its predecessors due to its compact structure. The plate type evaporator and microchannel condenser allow for exponential savings while cooling fluid(50% lower refrigerant charge); therefore, we have a strong, compact, safe and easy-to-use unit that also allows considerable equipment cost reduction.

SPECIFICATIONS

  • Capacity : 140 to 263kW (40 to 75TR)
  • Supplies chilled water from 7 to 12°C (44 to 53℉)
  • Refrigerant: Ammonia (R717)

WHERE TO USE

  • Beverages
  • Winery
  • Dairy products
  • Food
  • Chemical/Petrochemical
  • Pharmaceutical

Process cooling & refrigeration, ice pop hardening

NewTon i/B - glycol chillers for process cooling

NewTon i

A brine chiller with all the benefits of the NewTon series, including high efficiency, safety, and environmental friendliness. It is safe because the brine solution cooled with ammonia is sent to the process side. The amount of ammonia used to fill the unit is kept to a minimum, and it uses a shell and plate heat exchanger and a screw compressor equipped with a semi-hermetic IPM motor that is leak-resistant. As existing brine piping can be used, construction costs for system renewal can also be kept low.
・NewTon B
Standard type NewTon for process cooling.
・NewTon i
A NewTon unit specially designed for ice pop hardening. The refrigeration system is equipped with a shell and plate evaporator that uses corrosion-resistant titanium in the heat exchange part that comes into contact with the aqueous calcium chloride solution.
