● The touch screen interface has strong human-computer interaction, and the operation is simple and convenient.
● 7-inch LCD touch screen display.
● The exterior of the box is made of high-strength cold-rolled steel plate, and the surface of the box is powder-coated.
● 304 stainless steel inner tank.
● The height of the stainless steel shelf bracket is adjustable, which can be installed and removed at will, which is convenient for cleaning the inner cavity.
● The insulation layer of the box is made of high-density R245fa polyurethane foam as a whole, and the 126mm thick foam layer has extremely low thermal conductivity, which is more energy-saving. As a foaming agent, R245fa is environmentally friendly, has a high flame retardant coefficient, is non-flammable, and is safer.
● The door handle designed by bionics has a long lever arm and can open the door with one hand.
● Provide mechanical lock with padlock hole.
● Equipped with reinforced clapboard, the single-layer clapboard can bear up to 51kg.
● Equipped with a backup battery, which can continuously supply power to the display in the event of a power failure.
● Equipped with internal and external pressure balance valve.
● With anti-condensation function.
● Configure foam inner door.
● Heavy duty levelling casters.
