1. HW Series of Large-capacity Vacuum Compartment Refrigerators
Hitachi has released the R-HW60J model in its HW series of large-capacity refrigerators featuring the new moisture cooling function that maintains a cool moist atmosphere at a temperature of approximately 2°C, and a larger interior capacity while still having the same width as previous models.
The main features are as follows:
- The moisture cooling function uses a new separate compartment refrigeration system that helps prevent food from drying out while also keeping the compartment temperature at approximately 2°C to minimize the growth of germs on prepared meals and to keep food fresher for longer. The refrigerator is also able to prevent the warming of surrounding food if a container is placed in the compartment while still hot.
- The walls of the refrigerator have been made thinner without compromising insulation by adopting a well-balanced combination of a newly developed urethane foam with good flow characteristics and a vacuum insulation material with high insulation performance. This gives the refrigerator an internal capacity of 602 L with a width of 68.5 cm.
- The vacuum compartment is sealed and maintained at a pressure of about 0.8 atmospheres to minimize the oxidation and drying of food. It also keeps food fresher for longer by using carbon dioxide gas generated using a platinum catalyst (containing ruthenium) to suppress the action of enzymes on the food surface.
