the heat transfer controller mounted on the hot oil heater. This higher temperature will maintain
the heat transfer fluid at a higher temperature and will compensate for the heat required to raise
the temperature of the asphalt cement In the drums. Allow the temperature of the dedrummer to
rise to at least 250° prior to feeding drums into the unit This temperature Is checked on the dial
thermometer mounted on the front wall of the dedrummer tank.
