Hubei temperature shock test chamber, Hunan temperature shock test chamber information: Hubei temperature shock test chamber temperature range: -20 ℃ to 150 ° C, -40 ° C to 150 ° C, -60 ℃ to 150 ° C, -70 ° C. to 150 ℃ Second, the circulatory system of the refrigeration and air duct: refrigerator using the original French "Taikang" closed compressor. The refrigeration system unit or two to wind back the wind design, Hubei temperature shock test chamber per the cryogenic loop system design. Sirocco fan powerful air circulation system, allows uniform temperature distribution within the test area. The Wind Road circulating air pressure, wind speed according to customer requirements manufacturing non-meet testing standards, Hubei temperature shock test chamber door instantaneous temperature stabilization time can be faster. Refrigerant: DUPONT R404A (high temperature cycle), R23 the hypothermic circulatory; auxiliary parts: expansion valve (United States SPORLAN), solenoid valve (Italy CASTEL); filters (American SPORLAN); pressure controller (BAR RANCO); oil separator (Europe and the United States ALCO) refrigeration parts are imported. This product is in strict accordance with the impact of GJB150.3-86 GJB150.4-86 GJB150.5-86 high and low temperature test. National standards for manufacturing, and equivalent to meet GB, Hubei temperature shock test chamber to avoid any dead ends, the military standard; standard products also. I alternating high and low temperature humidity, Hubei temperature shock test chamber, cooling rate: from room temperature to -20 ° C ≤ 15min; throughout the average low temperature cabinet: RT to -20 ℃, Temperature fluctuation: ± 1 ° C 3 the effective size of the sample basket: 320 x 320mm 4, heating rate: from room temperature to 150 ° C ≤ 25min; (throughout average), temperature range: High Temperature Box: RT ~~ 150 ° C. precooling the lower limit temperature: ≤ -25 ℃; (undercooling ≤ -5 ° C) 7, the impact of temperature: at 150 ° C to -20 ° C, load: ≤ 20kg 9 Temperature error: ± 3 ° C professional sources of information: Wuhan still testing experience Equipment Co., Ltd.
