Replacing the Process Heater (Electric Dryers)

Large Dryers have a number of single phase Calrod-type heater elements wired in a delta formation. They are mounted on top of the dryer or to the drying hopper. The number and wattage of the heaters varies with model, voltage, temperature range, etc., but the replacement procedure is the same.

DANGER! Disconnect and lock out power before heater replacement.
