| Configuration of the equipment | ||||
| 1.Main Body -- AISI304 stainless steel. | ||||
| 2.Thermal insulation material -- BASF of Germany''sultra-low temperature insulation material multi-layer compositestructure. | ||||
| 3.Door seal -- Low temperature resistant siliconerubber imported from France,equipped with antifreeze die heatingsystem. | ||||
| 4.High temperature disinfection device--temperature up to 121 °C. | ||||
| 5.Efficient cleaning device-- health andsafety. | ||||
| Liquid nitrogen system | ||||
| 1. Liquid nitrogen system--- including liquidnitrogen tank (customer-supplied or optional),pressurizationsystem, insulated pipe, control valves, nozzles, dispenser. | ||||
| 2.DINTOR - ASCO (imported from USA)--- ultra-lowtemperature solenoid valve to ensure normal opened at -196 °C; | ||||
| 3.Liquid nitrogen nozzles---consist of hundreds ofmicropores,fully gasify the liquid nitrogen, then gasificationliquid nitrogen be ejected and circulated in the tank, to keep thetemperature uniform; | ||||
| 4.High efficiency and low noise axial fan, returnair distance is short, fast freeze, increased by 85% more efficientthan ordinary freeze. | ||||
| 5.Unique wind farm design---make the wind speed andtemperature of the frozen zone more uniform and stable. | ||||
| Control system | ||||
| 1.Control mode-- Touch screen PLC | ||||
| 2.Cylinder lock device-- to ensure that the doordoes not leak gas, and to easy to open and close the door. | ||||
| 3.Automatic locking function-- to ensure that thedoor is not open by misuse. | ||||
| 4.Interlock system-- if the door is not be closedwell,the freezer will not work. | ||||
| 5.Warning system-- if the door is not be closedwell,it will warn. | ||||
