| Configuration of the equipment | ||||
| 1.Main Body -- AISI304 stainless steel. | ||||
| 2.Thermal insulation material -- BASF of Germany's ultra-low temperature insulation material multi-layer composite structure. | ||||
| 3.Door seal -- Low temperature resistant silicone rubber imported from France,equipped with antifreeze die heating system. | ||||
| 4.High temperature disinfection device-- temperature up to +121 ℃. | ||||
| 5.Efficient cleaning device-- health and safety. | ||||
| Liquid nitrogen system | ||||
| 1. Liquid nitrogen system--- including liquid nitrogen tank (customer-supplied or optional),pressurization system, insulated pipe, control valves, nozzles, dispenser. | ||||
| 2.DINTOR - ASCO (imported from USA)--- ultra-low temperature solenoid valve to ensure normal opened at -196 ℃; | ||||
| 3.Liquid nitrogen nozzles---consist of hundreds of micropores，fully gasify the liquid nitrogen, then gasification liquid nitrogen be ejected and circulated in the tank, to keep the temperature uniform; | ||||
| 4.High efficiency and low noise axial fan, return air distance is short, fast freeze, increased by 85% more efficient than ordinary freeze. | ||||
| 5.Unique wind farm design---make the wind speed and temperature of the frozen zone more uniform and stable. | ||||
| Control system | ||||
| 1.Control mode-- Touch screen + PLC | ||||
| 2.Cylinder lock device-- to ensure that the door does not leak gas, and to easy to open and close the door. | ||||
| 3.Automatic locking function-- to ensure that the door is not open by misuse. | ||||
| 4.Interlock system-- if the door is not be closed well,the freezer will not work. | ||||
| 5.Warning system-- if the door is not be closed well,it will warn. | ||||
