11)
As the system continues to fill, the pump should resume operation. When the pump is running, water pressure at
the outlet of the pump should be approximately between 20
-
35 psi.
12)
During the fill operation if the water pressure does not exceed above 20 psi, ensure all the air vents are open.
13) Once all air is purged out of the system, the pressure at the pump outlet should remain steady.
4.2 PROCESS FLUID DELIVERY
Fluid delivery is accomplished via a jacketed pressure tank, jacketed valves, jacketed hoses, and a jacketed spray
nozzle (s).
The tank, is a pressure vessel that is pressurized with air to maintain a given setpoint at the nozzle location.
1)
To ensure complete heating in every possible liquid delivery component, including the ball valves mounted on the
tanks, are jacketed to maintain consistent heating. The hose delivering the fluid from the tank to the nozzles is
completely jacketed.
2)
Finally, the nozzles themselves are jacketed to maintain set temperatures. The tank is an ASME pressure vessel.
The tank comes equipped with 125 psi safety valve, air regulator, and ball valves.
3)
The main air supply goes into the inlet 2

way shut off valve.
4)
Before opening the pressure tank, make sure the pressure in the system is relieved.
