Stirred, Chemical, Laboratory, Pilot-plant Reactors, CSTRs, Autoclaves and fixed bed reactors

Agitated reactors (Autoclaves or stirred reactor) by PDC come in a broad range of alloys, capacities, and design pressures. We manufacture custom-designed stirred reactors for a variety of process reactions. Our stirred reactors are used in laboratories, pilot plants, and small-scale production facilities.

PDC constructs stirred reactors and pressure vessels from most machinable alloys. Capacities range from 50 cc to 500 gallons (2 m3). Agitated reactor design pressures range from full vacuum to 150,000 psig (10,300 bar). Temperatures range from -400 oF to 2,500 oF ( -200 oC to 1,400 oC).

Each stirred reactor is a complete system. This includes the reactor vessel, supporting stand, agitation assembly (magnetic stirrer, drive motor, belt, belt guard, impeller and digital tachometer), multiple process connections, drain, sample tube, temperature sensor, cooling coil and rupture disc assembly. Heating system and controls are optional.

We offer a complete skid mounted stirred reactor system complete with product loading, feed, reaction and receiving modules, mass balance and product analysis. We also offer a variety of controls from simple manual controls to advanced PC-based SCADA and DCS. Please refer to our pilot plant section for additional information.
