Security and Data Management

i.Series Upright ULT Freezers feature the i.C3 User Interface that provides constant temperature monitoring and control, security and multi-information logs

Heat Barrier System Reduces Frost

Heat Barrier System features a fortified outer door and a reinforced insulated inner door that prevents frost build-up by minimizing temperature fluctuations

Ice-Resistant Sealing Surface

An ice-resistant sealing surface features an energy-efficient hot gas loop for a frost-free door frame and composite panels reduce heat transfer

Frost Reduction

Polygonal gaskets on the outer door compresses against the frame and forms a tight seal that prevents migration of moisture and reduces frost build-up

Dual Blade Gaskets Eliminate Frost

Dual-blade gaskets between the swing-out inner doors (with a positive latch) stop warm air from entering the storage chamber for ensured temperature uniformity

Optimum Oil Management

Models feature an oil separator that protects the compressor and an optimized mixed refrigerant that ensures proper flow rate at extremely low temperatures

Ergonomic Door Handle with Key Lock

An easy-to-open door handle made with heavy-duty, cast aluminum and hardened steel includes a key lock and a padlock hasp for security
