This is a special lattice-type box cover which maintains moisture at an optimum level. Moisture from stored food is evaporated and then condensed on the lattice, maintaining the correct balance of moisture in the box. The compressor has a better energy efficiency ratio and can operate at voltage as low as 90V and as high as 310V, which means your refrigerator can work without a stabilizer too. This easy to clean removable airtight gasket seals in the freshness and keeps out the bacteria and dust particles accumulated in the door seal. It stops mould spores from entering and spoiling the food inside, keeping it healthy and hygienic for longer periods.
