Application

The Model L Electric Oil Heater is used for pre heating fuel oil as it is pumped through the piping system. It is usually installed on the discharge side of oil heaters that use steam or hot water as the heating medium to maintain oil temperatures during standby and cold starting conditions. It is also frequently installed in the oil return line to warm the lighter oils when it is necessary to avoid accumulations of paraffin wax in the piping system. For the latter application, a Preferred Model SB Suction Bell should also be installed in the tank to assure that warm oil will be drawn back into the suction line.
