These heaters reduce the
viscosity of oil by pre-heating, thus facilitating withdrawal of oil
from bulk storage.
OPERATION:
Steam or hot water flows through the tubes while oil
flows outside the tubes, which are baffled to assure efficient
heating.

CONSTRUCTION: Heads are cast iron or steel. Tubes are heavy
gauge steel. Tube sheets and baffles are steel. Tube bundles are
removable. Heads are removable without emptying contents of tank.
A special M & L swing valve is available which will permit
closing off the shell of suction heaters inside the oil tank so that
the tube bundle can be withdrawn, if required, without the necessity
of first emptying the tank.
ALTERNATE CAPACITIES-For other oil heating ranges, use
multipliers shown in the "Table of Multipliers". As an example, the
oil heating range in the "Table of Capacities" is 20° to 100° F,
when using steam at pressures shown. If the oil, however, is to be
heated from 40° to 120° F, instead of 20° to 100° F, multiply the
capacity shown in the "Table of Capacities" by multiplier 0.75,
obtained from the "Table of Multipliers", to arrive at the new
capacity for the alternate heating range.
NOTE: Table of Multipliers below to be used only with Tank
Outlet Oil heaters capacities above.
