1. Ash Systems

2. Electrostatic Precipitator Controls
If you need better opacity control and more flexibility in
scheduling rappers, REW can help.

3. Fly Ash

4. Fly Ash PLC Upgrades
Do your operators know when a feeder is plugged or a vent line doesn’t
open? With Smart Feed PLC controls REW can detect these problems
with an alarm before they become a maintenance issue.
Stop spending money fixing ESP curtains every outage. Prevent the
damage before it happens.

5. Fly Ash Controls
Many plants have 20 different operators running fly ash. Newer HMI
systems can simplify training and help with consistent operation.

6. Fly Ash HMI Screens
With detailed screen design REW can make the
system easy to run and troubleshoot.

7. Fly Ash Silos & Baghouses
Torn bags, low cleaning air pressure and failed DP
switches are typical challenges at the silos.
With smarter PLC controls and new transmitters, REW can
fix or alarm those problems before maintenance issues get
out of control.

8. Fly Ash Silo PLC Upgrades
After 30 years most control systems are badly deteriorated.
REW can make them better than new.

Ash

10. Bottom Ash PLC Upgrades
When your stepper switches fail or operators have to use
jumpers and manual valves to pull ash, it’s time to get rid of
the old relay controls. It costs less than you might think and it
makes it much easier to run and troubleshoot the system.
