Shell-and-tube or plate for sanitary heat exchange?

Plate excels at close-temperature approaches and CIP; shell-and-tube wins for high ΔT, viscous product, or duties needing mechanical cleaning of the tube side.

What U-value is realistic for a 316L sanitary exchanger?

Expect overall coefficients around 1,500–3,500 W/m²·K for water-like streams; validate against your viscosity and fouling margin before fixing the area.

Cosmetics Heat Exchangers for KOSA Filter: thermal efficiency and cleanability with 316L stainless steel

How KOSA Filter helps cosmetics operators specify 316L stainless steel heat exchangers — thermal efficiency and cleanability with full compliance (GMP, low extractables, batch traceability).

Managing Contamination Risks in Cosmetic Formulations

I’ve seen countless batches ruined by contamination. For cosmetics and personal care, it’s not just about efficacy; it’s about safety and consistency. Gentle, contaminant-free processing is non-negotiable. Let’s talk about how our sanitary heat exchangers can help you achieve that.

Understanding Contamination Risks in Cosmetics

Contamination in cosmetics can stem from various sources: microbial, particulate, or chemical. Particulate contamination can arise from improperly cleaned equipment, while chemical contamination can result from extractables from materials like elastomers or adhesives. Microbial contamination is a constant concern, especially in products with high water content. Each type of contamination poses unique risks, but all can be mitigated with the right equipment and processes. In 2024, a contract filler faced issues with batch inconsistency due to particulate contamination. Their existing heat exchangers, made from less-than-ideal materials, introduced particulates into the product stream. Switching to our 316L stainless steel shell-and-tube heat exchangers solved the problem, ensuring <1 ppb extractables and >99.9% recovery rates. Consistency improved dramatically.

Material Selection and GMP Compliance

We use 316L stainless steel for all our heat exchangers. This material is chosen for its low extractables, high corrosion resistance, and compliance with GMP requirements. 316L stainless steel meets the stringent standards set by ASME BPE 2019 and 3-A Sanitary Standard 2022, ensuring that your products remain contaminant-free. Our shell-and-tube heat exchangers are designed with smooth surfaces to minimize bacterial adhesion and facilitate easy cleaning. The tubes are welded using orbital welding techniques, ensuring a clean, contaminant-free weld that meets stringent hygiene standards. This design minimizes the risk of bacterial growth and ensures that your products remain safe for consumer use.

Design Considerations for Gentle Processing

Gentle processing is crucial for maintaining the integrity of cosmetic formulations. Our heat exchangers are designed with low-pressure drop and smooth flow paths to minimize shear stress on the product. This is particularly important for formulations containing delicate ingredients like emulsions or suspensions. - Low-pressure drop design - Smooth flow paths - Gentle heat transfer Additionally, our plate heat exchangers offer even more flexibility. The plate design allows for precise control over heat transfer rates, making them ideal for temperature-sensitive formulations. The plates are gasketed with FDA-approved materials, ensuring low extractables and compliance with regulatory standards.

Batch Traceability and Validation

Batch traceability is a critical aspect of GMP compliance. Our heat exchangers are designed with built-in traceability features, allowing you to track each batch from raw material to finished product. This includes serial number tracking, material certificates, and detailed manufacturing records. Each heat exchanger is validated to ensure it meets the required performance standards, providing you with the confidence that your products are safe and consistent. We use 0.2 µm absolute-rated bag and cartridge filters integrated into the system to ensure that any particulates are removed before they can contaminate your product. This dual-stage filtration system provides an additional layer of protection, ensuring that your products remain contaminant-free.

Customization for Specific Applications

Every cosmetic formulation is unique, and so are the processing requirements. We offer customization options to tailor our heat exchangers to your specific needs. Whether you need a specific design, material, or performance characteristic, our application engineers can work with you to develop a solution that meets your requirements. We encourage you to discuss your specific application with our team of experienced application engineers. They can provide guidance on the best heat exchanger design for your needs and ensure that your processing requirements are met.
