Glass lined reactor – BE type

Glass lined reactors are at the core of production activities wherever a reaction is run under aggressive acid conditions.
Our state-of-the-art glass lined reactors ensure quality, safety and reliability, satisfying multiple requirements such as:

  • Efficient and reproducible heat transfer
  • Effective and reliable mixing systems
  • Corrosion resistance
  • No contamination

They are designed and manufactured in compliance with DIN standards.
