Bunker Seal System

Prevent Coal Bunker Fires

Bunker Seal, an effective, reliable air-blocking system, is the antidote to the oxidation and moisture that leads to spontaneous combustion in coal bunkers, a serious danger to a power plant, its employees, and the value of the stored coal.


Coal Bunker Fire Prevention

Bunker Seal uses a manual spray nozzle and an air-powered pump mounted on a handcart to apply Soil-Sement®, a proven, gentle-on-the-environment polymer emulsion that seals the top of coal in bunkers to minimize oxidation, prevent spontaneous combustion and explosions.

You can breathe easier knowing that when you choose Midwest’s Bunker Seal System, you will eliminate oxidation that can lead to spontaneous combustion, a major safety threat, and extended plant downtime. Contact Midwest for the leading coal bunker fire protection product on the market.
