Reactor size should be selected based on the required working volume. In most applications, the recommended working volume is approximately 60–80% of the total reactor volume, leaving sufficient headspace for mixing, thermal expansion, foaming, gas evolution, and solvent reflux. Processes that generate significant foam or gas, or those with future scale-up plans, may require a larger vessel. Factors such as batch size, material properties, process conditions, and anticipated production growth should all be considered to ensure optimal heat transfer, mixing performance, and operational safety. If you're unsure which reactor size is right for your process, contact our engineering team for a customized recommendation.

Not always. Stainless steel is the preferred material for most pharmaceutical, food, biotechnology, and general chemical applications due to its durability and cost-effectiveness. However, highly corrosive processes may require alternative materials such as PTFE-lined vessels for exceptional chemical resistance, duplex stainless steel for high-salinity environments like seawater, or Hastelloy for aggressive chemical applications. Material selection should always be based on process compatibility. We offer customized reactor and vessel solutions tailored to your process requirements, please contact us to discuss your application.

The standard SR Series stainless steel reactors operate from -20°C to 220°C, with a maximum design temperature of 250°C for short-term operation. Customized versions can be configured for temperatures as low as -80°C or as high as 300°C, depending on process requirements. High-temperature operation places greater demands on sealing performance, safety, and thermal management. We recommend several upgrades to ensure long-term reliability, including a high-temperature bottom ball valve, metal gasket sealing, water-cooled mechanical seals, and thermal insulation to improve sealing performance, reduce heat loss, and extend equipment lifespan.

Material quantity can be monitored using either level sensors or weighing systems. Traditional level sensors, such as differential pressure, radar, or tuning fork sensors, are mounted on the vessel lid and detect liquid levels directly. However, measurement accuracy may be affected by agitation and surface fluctuations. For higher accuracy, we recommend weighing modules (for floor-standing reactors) or platform scales (for benchtop reactors). These systems do not contact the process media and are unaffected by mixing turbulence. By measuring the total vessel weight, they provide a reliable and precise indication of material quantity throughout the process.

Yes. The SR Series can be upgraded with a PLC + HMI touchscreen control system for enhanced process monitoring and data management. Typical functions include parameter setting and real-time display (speed, temperature, weight), weighing system calibration, historical trend curves, data logging and USB export, audible and visual alarms with event records, as well as system settings such as user management, time configuration, default parameters, and data maintenance.

The SR Series reactors can be equipped with an optional spray ball cleaning system for CIP (Clean-in-Place) operation. Connected to an external CIP unit, the cleaning solution is pressurized and distributed through the spray ball, providing full internal coverage of the vessel surfaces. This enables efficient cleaning without disassembling the reactor, reducing downtime and labor requirements. CIP systems are particularly suitable for pharmaceutical, biotechnology, food, and other hygienic processing applications where validated and repeatable cleaning is required.

The SR500 Series is equipped with a variable-frequency drive (VFD) motor, which provides reliable and cost-effective speed control for general mixing applications. The SR600 Series features a servo motor with encoder feedback, enabling precise speed control and automatic torque compensation to maintain stable agitation even under changing viscosity and load conditions. It is ideal for processes requiring stable agitation speed and consistent mixing performance.  Motor selection should be based on the specific process requirements. Higher-speed, higher-torque, and customized drive solutions are also available upon request.

We offer several metering and transfer solutions, including peristaltic pumps, gear pumps, and diaphragm pumps. The optimal choice depends on the liquid properties (viscosity, corrosiveness, and solids content), required flow rate, and process pressure conditions. Peristaltic Pumps – Ideal for low- to medium-viscosity liquids, corrosive media, and fluids containing small particles. Simple maintenance and contamination-free fluid handling. Gear Pumps – Suitable for medium- to high-viscosity materials such as oils, resins, polymers, and adhesives. Provide a stable and continuous flow. Diaphragm Pumps – Designed for precise dosing of corrosive liquids, solvents, acids, and alkalis, with excellent chemical resistance and flow control accuracy. Our engineering team can recommend the most suitable pump configuration based on your specific process requirements.

Yes. Our SR series reactor features jacketed design, precise temperature control, mechanical agitation, and an integrated condenser, making it suitable for polymerization and other temperature-controlled chemical reactions.
