Sanitary Tube-in-Tube Heat Exchangers
Handling fluids with suspended solids requires specialized heat transfer solutions to prevent clogging and ensure efficient processing. Southwest Thermal’s sanitary-grade stainless steel tube-in-tube heat exchangers are designed for these challenging applications, offering exceptional corrosion resistance and compliance with hygiene standards like 3A and FDA. These units provide efficient heat transfer for fluids containing particulates, such as slurries, pulps, or suspensions, in industries like food and beverage processing, pharmaceutical production, chemical processing, and wastewater treatment.
Constructed from 316L stainless steel with polished surfaces (Ra = 32 µin), these exchangers prevent microbial growth and facilitate easy cleaning through Clean-in-Place (CIP) systems. The tube-in-tube design, with its smooth, wide-flow paths, minimizes fouling and ensures reliable performance with viscous or particulate-laden fluids. These exchangers are customized to handle specific solid concentrations and flow rates, with ASME and 3A certification available for industry compliance.
The compact and versatile design of tube-in-tube heat exchangers makes them ideal for processing solids in suspension, ensuring hygiene, durability, and efficiency in demanding sanitary and industrial environments.
Heat exchanger operations for solids in suspension involve several critical steps to ensure efficiency and hygiene:
- Fluid Preparation: Fluids with suspended solids are pre-treated to ensure compatibility with the exchanger, adjusting viscosity or particle size as needed.
- Heat Transfer: The process fluid with suspended solids flows through the inner tube, while a heating or cooling medium flows in the annular space, ensuring efficient heat transfer.
- Temperature Control: Precise regulation of temperatures prevents degradation of sensitive solids or clogging due to overheating or overcooling.
- CIP Integration: Automated CIP systems circulate cleaning agents to remove residues and maintain hygiene without disassembly.
- Testing: Post-process testing verifies fluid temperature, purity, and quality to meet industry standards.
Each stage relies on the precision and durability of stainless steel tube-in-tube heat exchangers to handle solids in suspension while maintaining efficiency and hygiene.
