Description
Description Description
Installed in the fluid return line. Also known as the BPR, it is controlled pneumatically
to maintain fluid pressure in the fluid circulation system.
Allows control of the Back Pressure Regulator (E), either locally using the Pump
Control Module (PD) or remotely using the Touchscreen Box (J).
amount of fluid, filled as needed from the Secondary Tank (H) and constantly stirred
by the Agitator (L). As fluid is pumped through the paint kitchen, fluid is continuously
drawn from and returned back to this tank.
Contains the fluid used to fill the Primary Tank (G) as needed. Must be manually
refilled or replaced when empty. The tank or drum may have an Agitator (R) and
Radar Level Sensor (T) installed for communication with the Intelligent Paint Kitchen
software.
A user interface for setup, operation, and monitoring of system devices. It must be
installed in a non-hazardous location.
The Touchscreen Box can be connected to a Supervisor Box (A). It communicates
with the Supervisor Box using Modbus TCP.
One or two Pressure Transducers may be installed to measure the pressure inside
the paint kitchen circulation lines. Each Pressure Transducer communicates with the
Supervisor Box (A), which monitors the pressure and controls the E-Flo DC Pump (C)
to maintain the fluid pressure of the fluid leaving the pump. The Pressure Transducer
can monitor pressure at the pump outlet, at the Back Pressure Regulator (E), or both.
Continuously mixes and stirs the contents, preventing fluid from separating, setting,
or drying on the inside of the tank. This agitator can be either a Graco electric agitator
or a user-supplied agitator.
If an electric agitator is used, an additional Variable Frequency Drive/Inverter (B)
is needed to control the agitator speed.
Detects and communicates the fluid level in the Primary Tank (G).
Air-operated double diaphragm pump for use in the hazardous location. Its purpose
is to fill the Primary Tank (G) from the Secondary Tank (H), as needed.
Activates the Pneumatic Remote Transfer Fill Pump (N) whenever fluid in the Primary
Tank (G) falls below the level specified in the Intelligent Paint Kitchen software. When
the Primary Tank is filled to the user-specified level, the pump shuts off.
Intrinsically safe control module with user interface for use in the hazardous location.
One is needed for each E-Flo DC pump (C). The Pump Control Module connects to
the pump and pump-related components. It provides the communication connection
between the station and the Supervisor Box (A). Connects to the Supervisor Box
by a pair of fiber optic cables.
