Drying and solidifying oven for transformer coil

Thisoveniscircularventilationdryingequipmentwith automatic control ofthe whole process.Itisequippedwithhigh 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 ofhigh precision temperature control, easy operation,energy saving, safetyand high reliability,are widely used intheproductionoftransformerindustry,transformercoilimpregnationdrying(solidifying) processandepoxypouringsolidifying process, etc.
