Carbon dioxide incubator is composed by box configuration , temperature control system and CO2 thickness control system.
• Box configuration is composed by crust , heat preservation material , stainless steel water jacket . The design of the work room is linchpin . It is adopted the water jacket technology , namely , except the front glass door , other 5 surfaces are all stainless steel interlayer full with water . With hot water circulation , water interlayer in same temperature surrounds the work room . Heated equably , temperature invariableness , the fast rising temperature and the slow falling temperature are the advantages of this work room . Though power cut for 5-6 hours , it can also make the cell alive . Adopt the design of double door , the glass door inside is convenient for observation of dew and other influence . The air in the work room can be circulated by fans for uniformity of the temperature and CO2 thickness in work room . The top of the water jacket is step shape (declared the nationality patent) , for uniformity of the mater tier in incubator and prevention of high temperature in work room . The manufacturing technical can also guarantee the shape of the incubator .
• The circuit of 3-route check , 3-step control and high temperature prevention is adopted in temperature control system . (some import incubator circuits are single route check ,2 step control) Temperature sensor is unusually adopted the voltage concentration circuit .
• CO2 thickness control is adopted the ultrasonic sensor with stable capability , fast checking speed for adaptation of the wet environment , long service life and good linearity . (Declared the nationality patent) . But the same kind of this products in the world are adopted the heat conduction and infrared . The sensor configuration of the heat conduction is simpleness and low expedition , but it is sensitive by environment influence and easy to zero drift . The infrared sensor can't work in wet incubator , so it is adopted with the outlay sensor by pump the air inside and check after freezing , and then it will send the air back to the incubator . This system has disadvantages of complex duct , high mechanical waste , hysteresis checking result and high fault rate .
Auto-control of CO2 thickness and comparison of flow are worked when a value is set , so it has the advantages of easily operation , high gas save , high precision and good stabilization .
• The configuration of water jacket with the patent technology makes the incubator surrounded by water interlayer for high capacity of the water jacket .
• Adopt the sensor of 3-route integrated circuit for precise control of water temperature, door temperature , room temperature and prevention influence of environment temperature. Over temperature with the protection of double layers for safety .
• Adopt the ultrasonic sensor , low mechanical waste , long service life , good stabilization , no influence by high humidity .
• Temperature and CO2 thickness can be controlled separately . Work alone with high precise .
• The digital display of temperature and CO2 thickness , the LED display of door rising temperature , water rising temperature and water level variety .
• The large incubator (200L) is adopted with double glass doors for prevention influence of door opening and fast recover of the environment .
• The small incubator (50L) can be used as table-type for fast recover of the temperature and CO2 thickness . |
