Tightness:
This is the first consideration in choosing refrigerators. Although different brands of products have different sealing methods, the sealing property of Karo is a necessary condition for keeping food in storage for a long time.

Heat and cold resistance:
Refrigerators have high requirements for heat resistance and cold resistance. They will not deform in high temperature water and can even be disinfected with boiling water.

Durable:
To have superior impact resistance, for example, the car is not easy to crack when pressed or hit, and will not leave scratch, and can be used for life.

Multi function and diversity:
According to the needs of life, different sizes of ice bags are designed and used with reusable technology. The ice bags can keep cold and keep hot (the ice bags can be frozen to - 190 ℃ at least and heated to 200 ℃ at most), and can be cut in any size

Fresh keeping:
The international standard of airtight measurement is based on the moisture permeability test. The high-quality refrigerators have 200 times lower moisture permeability than similar products, and can keep things fresh for a longer time.

Cooling time:
The ice in the general incubator will melt in 24-48 hours when put into two thirds of the time. The material and thickness of the thermal insulation layer of a good heat preservation refrigerator determine the time of heat preservation and cold storage under specific ambient temperature. The longest ice block can be refrigerated for up to 10 days
