SILICONE RUBBER HOPPER HEATERS - APPLICATIONS:
Eliminate Bridging, Pluggage, Condensation, and Corrosion on:

• ESP (Electrostatic Precipitator) Hoppers
• Bag house Hoppers
• Most Material and Dust-Collector Hoppers
  

 

CONTROL BRIDGING and CORROSION in HOPPERS:
   
Eliminate Hopper Corrosion    Eliminate Hopper Sledgehammer

Good for Hoppers with...

• Bulk Powder
• Fly Ash
• Resin Beads
• Any System Where Bridging or Condensation Can Occur

 

How Does Corrosion Occur in Hoppers?
Condensation builds as moist air contacts cold hopper walls causing corrosion.

How Does Bridging Occur in Hoppers?
Fly ash and other solid particles accumulate on moist walls leading to bridging.

Stop Bridging and Corrosion by Heating Hopper Walls!

What is Necessary to Apply Heat?
A hopper surface heating system provides everything necessary to stop bridging and corrosion including...

• Heaters
• Temperature Controllers
• Accessories
• Application / Installation Assistance
