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 °C. |
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 °C; |
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. |
