1. Paint Circulation Technology Level 1 - Training Document
Subject Matter Expert: Miguel Bahena

2. What Is A Paint Circulating System
A pressurized vessel used to transport material to various locations. More efficient then manual moving material to individual locations.

3. Sounds simple doesn’t it?
What Are We Doing?
Moving material from point A to point B.
Supply material fluid pressure.
Supply material fluid flow.
Maintain material integrity.
That is all we do!

5. PAINT MIX ROOM Typical paint mix room
The martial that is used for painting the vehicles is a solvent borne material which is extremely flammable. The paint is stored and pumped from a paint mix room.
MIX ROOMS ARE CLASS 1 DIVISION 1 AREAS – NO ELECTRIC ITEMS ARE ALLOWED IN THIS ROOM INCLUDING – (CELL PHONES, FLASH LIGHTS, RADIOS, ETC). UNLESS APPROVED BY FORD SAFETY

7. PAINT CIRCULATION HEADER Typical paint circulation header
The paint is pumped from the paint circulation module to the spray booths in what is called a header system. The headers system is constructed from stainless steel pipe/tubing and delivers paint to each robot or manual spray station.
At each robot or manual station, a line tee’s off the header to feed this station. This is called a drop/paint station.

8. PAINT HEATEXCHAGNER SYSTEM
The paint must be applied to the vehicle at the correct temperature. A paint heat exchanger system is used to maintain a temperature of +/- 2 degrees F
Tube and shell heat exchanger
Water supply and return lines
Water conditioning skid

9. WASTE COLLECTION SYSTEM
Each time the robot or manual station changes color a certain amount of waste is generated. This waste is collected at the paint booth in a waste collection system.
Special Waste Collection Funnel Under Cap Cleaner to Flush Drop Legs and Prevent Debris from Entering Waste Header
Recirculation of the header and drop legs are very important
Gravity Waste Header Fabricated from 2” S.S. Tubing Utilizing Sanitary Fittings for Smooth ID and Ease of Maintenance. Line Installed at ¼” – 3/8” per foot to maintain proper drain velocity
Ball Valves Added to Header to Have the Ability to Power Flush Header for Preventative Maintenance
Purge Solvent Piped to Tank so Virgin Solvent Can be Added for Cleaning. A Catalyst Stop can be Substituted to Prevent the Catalyst from Curing (paint supplier can recommend material)
Special Cage Inside Tank to Capture 2K Waste Debris From Clogging Pumps
Utilize (1) Pump for Recirculation and (1) Pump for Empting of the Tank
