Description
This drying oven can be widely used in the production of transformer industry, transformer coil impregnation drying (solidifying) process and epoxy pouring solidifying process, transformer active parts drying, etc. It features high precision temperature control, easy operation, energy saving, safety and high reliability.
Properties
1. As a kind of transformer drying equipment in China, this drying oven can control the whole process automatically.
2. Centrifugal blower with high temperature resistant is installed. The blower make the hot air circulate in the oven.
3. It is equipped with heating chamber, which can heat the air in the work piece. After that the hot air will exchange in work pieces, then back flow to air duct. Then the air in oven can be heated again and circulated again, finally make the inner temperature meet technological requirements.
