Transformer coil drying oven
Transformer coil drying curing furnace
The oven is a circular ventilated drying device, which can automatically control the whole process. Equipped with high temperature resistant centrifugal blower. A heating chamber installed in an oven heats hot air. The blower circulates hot air in the oven, which is then heat exchanged with the workpiece and returned to the duct. The air is then reheated and circulated once in the oven to bring the internal temperature up to the technical requirements
The oven has the characteristics of high temperature control precision, simple operation, energy saving, safety, high reliability, and is widely used in the transformer industry, transformer coil dip drying (curing) process and epoxy casting curing process.
