Glass lined reactor – BT type

Glass lined reactors are at the core of production operations 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 ASME standards.

Glass lined reactors are used for multiple applications, from API (active pharmaceutical ingredients) synthesis to hydrometallurgy, across different industries, such as:

  • Base chemical
  • Chloralkali
  • Crop protection
  • Flavours & fragrances
  • Pharmaceutical
  • Precious and technology metals

They can be provided as standalone units or modular turnkey systems to simultaneously satisfy functional needs and efficiency in project costs and execution time.
