Daiwa cooler's new index "KEEP":
The most important thing for a cooler box is how long it retains ice! Daiwa expressed this index as "KEEP○○". "KEEP" calculates the ice residual rate based on the simple method of the JIS standard (JIS S 2048: 2006). Furthermore, the time required for the ice to completely melt is expressed as a value called "KEEP○○".

[What is measurement using the JIS simple method? ]
A cooler box filled with ice cubes equivalent to 25% of the cooler box's capacity was left in a constant temperature room adjusted to an outside temperature of 40°C.
After 8 hours, measure the weight of the ice and calculate the remaining percentage of ice.

[What is KEEP conversion? ]
From the remaining rate of ice, the time until the remaining rate reaches 0% is calculated and displayed as a value of "KEEP○○".

Insulation material holds the key to cold storage performance:
Differences in cold retention performance occur mainly depending on the insulation material used.
Daiwa offers the following 3 types of insulation materials and 6 types of insulation structures, allowing you to choose the optimal cooler for your application.

*Thermal conductivity = A value that expresses the ease with which heat is transmitted through each insulation material.The smaller the value, the more difficult it is for heat to be transmitted.
