BP-8030-U |
Ventilation aging testing machine |
CONVECTION AND VENTILATION AGING OVEN |
■ Explanation This machine is used to test the thermal aging performance of rubber, plastic, and various insulation materials, in order to compare the tensile strength and elongation of the test pieces before and after aging. The machine uses hot air circulation to promote the aging of the test pieces. The inner box has good airtightness and is equipped with a device for extracting air from the inner box. It is also equipped with over temperature automatic cut-off protection. The replacement of the grid can also be used as a drying machine. |

Formula for calculating the number of air changes per hour
N=3950(x-Y)/VD△T
N: air changes per hour
X: Electricity consumption (W) during ventilation
Y=average power consumption W, with no ventilation,
W: Electricity consumption (W) without ventilation
V: Box area (cm3)
D: Indoor air density during testing (g/cm3)
△ T: Temperature difference between inside and outside the box
