Stirred Tank Reactor (STR)

Stirred Tank Reactors (STRs) are the most widely used type of process reactor in chemical and pharmaceutical manufacturing. They allow precise control of temperature, pressure, and mixing for batch or semi-continuous reactions.

Key Features

• Full or half-pipe jacket for heat transfer (steam, hot water, thermal oil, chilled water)
• Multiple agitator types: Rushton turbine, pitched blade, anchor, gate, helical ribbon
• Design pressures from full vacuum to 50 Bar; cryogenic service available
• Multiple nozzles for instrumentation, charging, venting, sampling
• Baffles (2-4) for improved mixing; internal coils as additional heat transfer
• ASME Section VIII / IS 2825 design and fabrication with third-party inspection

Applications

Organic synthesis, polymerization reactors, sulfonation, nitration (with suitable materials), esterification, saponification, pharmaceutical intermediates, dye manufacturing.
