Product Details

Drying oven

This oven is circular ventilation drying equipment with automatic control of the whole process. It is equipped with high temperatureresistant centrifugal blower. Heating chamber installed in the oven can heat hot air. Blower make the hot air circulate in the oven, hot air will heat exchange with work pieces, then backflow to air duct. Then air be heated again and circulated in the oven again and again to make the inner temperature meet technological requirements

The oven has features of high precision temperature control, easy operation, energy saving, safety and high reliability, are widely used in the production of transformer industry, transformer coil impregnation drying (solidifying) process and epoxy pouring solidifying process, etc.
