Walt — Simple Man Takeaway
Cooling is not about making water move. It is about giving heat a way out.
Plain-English Summary
Use this flow when equipment or process temperature rises, cooling recovery slows, heat exchangers underperform, flow switches trip, or cooling water flow becomes unstable. If heat cannot leave, quality, uptime, and equipment life suffer.

Field Checks
- Define the cooling failure
- Compare supply and return
- Check pressure points
- Check pump health
- Check restrictions
- Check proof signals
- Check glycol and weather
- Compare heat load
Watch Out For
- Flow switch proves but exchanger is fouled
- Glycol protects from freezing but reduces heat transfer or increases pumping load
- Strainer plugged after maintenance or seasonal startup
- Closed or partially closed valve
- Air pocket or bypass path
- Temperature sensor blamed before cooling path checked
- Cooling demand changed with speed/product/process
Reverse-Trace / Ghost Busting™ Decision
if pump command, valve command, flow-proven bit, or temperature-permissive logic is blocked.
if flow switch, pump feedback, valve feedback, or temperature signal drops intermittently.

Walt says STOP! - Safety First
Make these checks prior to proceeding.
Stop and follow site procedures when hot water, steam, pressure, chemicals, glycol, electrical equipment near water, or automatically starting pumps are involved. Treat pressurized hot water and chemical treatment systems with respect.
