304 Stainless Steel Forced Circulation Crystallizer With PLC Control for Chemical Processing
Product Spotlights
Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer since 1998, with annual export value exceeding US$5 million. We proudly present our 304 Stainless Steel Forced Circulation Crystallizer with PLC Control, designed specifically for demanding chemical processing applications. This advanced crystallizer combines robust construction with intelligent automation, ensuring efficient crystallization and consistent product quality. Our decades of manufacturing experience guarantee reliable performance for your production lines.
The forced circulation design ensures high heat transfer rates and uniform crystal growth, making it ideal for processing solutions that require precise supersaturation control. The crystallizer is built from 304 stainless steel, offering excellent corrosion resistance against a wide range of chemicals, including acids, alkalis, and salts. The integrated PLC control system allows real-time monitoring and adjustment of key parameters such as temperature, pressure, circulation rate, and crystal size distribution.

Benefits for Your Chemical Processing: The forced circulation crystallizer improves yield by maintaining optimal supersaturation, reduces scaling and fouling, and produces uniform crystals with narrow size distribution. The PLC control minimizes human error, reduces labor costs, and allows easy integration into existing plant automation systems. This equipment is widely used in the production of fertilizers, salts, pharmaceuticals, fine chemicals, and wastewater treatment.
FAQ – Frequently Asked Questions
-
Q: What types of chemicals can be processed with this crystallizer?
A: Our 304 stainless steel crystallizer is suitable for most neutral and mildly corrosive solutions, including sodium chloride, potassium sulfate, ammonium nitrate, citric acid, and many organic compounds. For highly corrosive media, we recommend exploring higher-grade alloys. -
Q: Is the PLC control system compatible with my existing DCS?
A: Yes, the PLC supports standard communication protocols such as Modbus, Profibus, and Ethernet/IP. We can customize the interface to match your plant control system. -
Q: Can you provide a crystallizer with a specific working volume?
A: Absolutely. We offer custom sizes from laboratory scale (5 L) to industrial scale (100,000 L). Please provide your process requirements for a tailored solution. -
Q: What is the typical lead time for this equipment?
A: Standard lead time is 30–45 days after order confirmation, depending on customization complexity. Urgent orders can be discussed. -
Q: Do you provide installation and commissioning support?
