Control system: Cryogenic chamber The system consists of button switches, relays, intelligent temperature controllers, temperature sensors, recorders, pneumatic opening switches, etc. The selected temperature control instrument has PID automatic adjustment function, multiple process curves can be set, each curve can be set step by step, with process recording function, remote monitoring function, after all procedures are completed, the alarm will automatically power off. Electrical operation is divided into manual and intelligent instrument control, which can be switched through the manual / automatic selection switch on the control cabinet panel, and can be switched during the operation of the equipment. Cooperate with electrical interlock and alarm to ensure safe use. (Individual electrical box, human-machine interface input, PLC intelligent control and industrial control computer control can be designed when special requirements)
Insulation system: It is composed of an inflatable pipe insulation system and a box insulation system. The cryogenic box insulation system consists of a special insulation layer with a thickness of 150mm and a special thickness of up to 200mm, which can effectively block the exchange of cold and heat inside and outside the box to reduce the consumption of liquid nitrogen. An elastic silicone ring and a double-layered wool felt seal are installed between the upper cover and the box body. Equipped with a tunable locking device. The temperature between the outer wall of the box and the room temperature does not exceed 10 ° C.
Nuoruida (Tianjin) science and Technology Co., Ltd. is committed to research, development, and sales of liquid nitrogen cryogenic equipment which is establish in 2002. Using European technology, we provide a variety of equipment. The main equipment is liquid nitrogen equipment, cryogenic furnace, cryogenic processing equipment, low temperature assembly equipment, cryogenic assembly equipment, and so on.
