Structure Design

Stainless steel is the lead material in these freezers. We believe that comfort is an important factor that is why there are four casters, so that the freezers can be very easy to handle. They also have a front opening lockable door with a new ingenious handle with an easy open and close function. It is important to know that these freezers also have a vacuum release port. The shelves’ material is also stainless steel with inner insulation doors and a double silicon gasket seal. The insulation is the best: two-time foaming technology with 100-155mm of foaming insulation and VIP insulation board. There is also USB store functions and you have the option to have a chart recorder, a CO2 back up system, storage rack or boxes and a remote alarm system.
