Jacketed Cooling/Heating System for Crystallization

Product Specifications

Technical details and manufacturing context for Jacketed Cooling/Heating System

Definition

The Jacketed Cooling/Heating System is a component of an Industrial Chemical Crystallization Unit. It consists of an outer jacket surrounding the crystallization vessel, through which heating or cooling media circulates. This design enables precise temperature control during supersaturation, nucleation, and crystal growth phases by transferring heat through the vessel walls, ensuring uniform thermal conditions for optimal crystal formation, size distribution, and purity. The system is available in materials such as Stainless Steel 316L, Carbon Steel, and Hastelloy, with wetted parts typically in 316L (optional Hastelloy) per ASTM A240. Key parameters include an operating pressure of 1.0–1.6 MPa, operating temperature of -40 to 200°C, heating/cooling capacity of 5–50 kW, temperature control accuracy of ±0.5°C, jacket volume of 10–500 L, heat transfer area of 0.5–10 m², flow rate of 1–20 m³/h, power supply of 380–480 V AC (IEC 60038), electrical power consumption of 2–15 kW, ingress protection of IP54–IP65 (IEC 60529), and weight of 200–2000 kg. These values are directory reference ranges and must be confirmed for the specific model and application. The system is designed for integration into crystallization units, with interfaces for media supply, electrical connections, and process control. Verification questions should address actual operating conditions, media compatibility, and compliance with relevant standards. Maintenance signals include temperature control deviations, pressure fluctuations, and media leaks. Failure boundaries include gasket degradation above 200°C. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

Thermal energy transfer occurs through the vessel wall separating the process fluid from the heating/cooling media circulating in the jacket. Heating media (e.g., steam, hot oil) or cooling media (e.g., chilled water, glycol) flows through the jacket space, with temperature controlled by regulating media flow rate, temperature, and pressure. The system maintains precise thermal profiles by adjusting media conditions based on process requirements. This allows for controlled cooling or heating rates essential for crystallization, ensuring uniform temperature distribution and preventing local overheating or undercooling.
