Clean non-oxidizing high temperature chambers can prevent products from oxidation under high temperature. It is ideal for application in semiconductor, liquid crystal, electronic products and precision appliance industries.
Reference Standards GB/T2423.2-2008 Environmental Testing for Electric and Electronic Products - Part 2: Test B: High Temperature Test Method GJB150.3A-2009 Military Equipment Laboratory Environment Test Method Part 3: High Temperature Test IEC68-2-2 Test B: Dry heat GB/T 25915.1-2021 Cleanrooms and associated controlled environments Part 1: Classification of air cleanliness by particle concentration Features High temperature resistant high efficiency filter, keeping the internal Cleanliness level of the high temperature chamber (in a class 10000 cleanroom) at grade 100 through vertical circulation. Circular arc in the chamber designed to prevent accumulation and settlement without dead angle. The inner chamber adopts jacket design, ensuring the cleanliness of the inner chamber during cooling. Using air to achieve rapid cooling, saving a lot of nitrogen compared with traditional models. Special temperature controller. Small temperature fluctuation and deviation. Manually adjusted nitrogen flow and display of the float flowmeter scale The solenoid valve controls the nitrogen flow to decrease when the temperature is stable (after oxygen content is reached). Optional Function Automatic regulation of inert gas flow by electronic flowmeter software Online oxygen concentration analyzer SpecificationsModel | SVC-NO-91 | SVC-NO-216 | SVC-NO-512 | ||||
