Required Pressure Drop Across the Heater
The thermal  uid pressure drop across your heater is critical. This should be
recorded at the completion of start-up, as follows:
1. The pressure drop value is obtained by subtracting the heater outlet
pressure from the heater inlet pressure when the thermal  uid is at normal
operating temperature.
2. At the recommended standard  ow rates, and .7 sp gr, the pressure drop
cross the heater should be as shown in Table 10.
3. In the event of an abnormal reading, contact Fulton Service immediately.
Failure to take immediate action in the event of reduced  uid  ow may
result in rapid and serious degradation of the  uid, with possible damage
to the heater.
