32℉ (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 33℉ (0.5°C ) 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: 56.7TR (197kW)
- Supplies chilled water from 33 to 36℉ (0.5 to 2°C)
- Refrigerant: Ammonia (R717)
WHERE TO USE
- Poultry processing plants
- Food processing plants
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.
