High Pressure Boiler Manufacturers IQS Directory

Boilers are classified as high pressure when they generate steam pressures above 80 bars. The larger the variance between the temperature of the stream while rising and the steam once it leaves the boiler, the higher efficiency achieved. High pressure boilers produce pressures greater than 15 pounds per square inch (PSI).
