In the event of an obstruction in the line, the Fulflo will open and divert fluid from the delivery TO PROCESS line to the return From Process line. A constant flow of fluid is maintained through the heater tank to prevent damage to the heating elements and fluid.
Cooling
Optional
The
The modular construction (unique to Sterlco units) allows the tube bundle to be easily removed for periodic cleaning. Additionally, check valves are installed on the water supply and drain lines to prevent water from back flowing into the heat exchanger from a closed drain or into the water supply piping.
The controller automatically regulates cooling by opening and closing the cooling solenoid. This allows the proper amount of oil to pass over the tubes of the heat exchanger. A water supply of 75 psi (517.1 kPa/5.2 bars) maximum is required for connection to the heat exchanger.
Connection Lines
Connections for TO PROCESS and FROM PROCESS lines are:
•2" NPT (50.8 mm) at 90 gpm (341 lpm)
•
•3" NPT (76.2 mm) at 200 gpm (757 lpm)
Water connections for COOLING WATER SUPPLY and
COOLING WATER DRAIN are:
•¾” NPT (19.1 mm) for 3.9 & 6.7 sq. ft. heat exchangers.
•1" NPT (25.4 mm) for 13, 21, & 27 sq. ft. heat exchangers. (See Chapter 3.) The customer is responsible for conversions to metric standards.
