Stainless steel shell and tube heat exchangers are engineered for superior heat transfer efficiency while meeting the strictest hygiene standards required in industries such as food and beverage, pharmaceuticals, biotechnology, and cosmetics. These designs prioritize contamination prevention, ensuring product integrity and compliance with regulatory standards. The robust construction of stainless steel ensures durability, corrosion resistance, and compatibility with aggressive cleaning protocols.
The design features a series of stainless steel tubes housed within a cylindrical shell, facilitating efficient heat transfer between two fluids without mixing. One fluid flows through the tubes, while the other circulates around them within the shell. Smooth, crevice-free surfaces minimize bacterial growth, and features like full drainability and clean-in-place (CIP) compatibility simplify maintenance. Custom designs are tailored to specific applications, accounting for factors such as fluid viscosity, flow rates, and temperature requirements, ensuring optimal performance for processes like pasteurization, sterilization, and product cooling.

Stainless Steel Shell and Tube Heat Exchanger Design
Our stainless steel shell and tube heat exchangers are meticulously designed to meet the rigorous demands of industries requiring high hygiene and performance standards, such as food, beverage, dairy, and pharmaceuticals.
Types of Shell and Tube Heat Exchanger Designs
Available in both standard and custom configurations, our designs feature 304L or 316L stainless steel for superior corrosion resistance and sanitary compliance. Built to TEMA Class C and ASME standards, they are hydro-tested and code-stamped for reliability. U-tube designs accommodate thermal expansion, while shell expansion bellows support high-temperature swings. Replaceable O-rings and tube bundles, sizes from 4" x 36" to 10" x 54", and 3-A Sanitary Standard upgrades ensure versatility and compliance.
Design Features
Standard designs include 304L stainless steel tubing, welded and bright annealed, with a 40Ra exterior finish. Custom options include 316L stainless steel, seamless 3-A compliant tubes polished to 32Ra, chloride-free insulation jackets, and configurations for vertical or horizontal mounting. Additional features like double tube sheets, expansion joints, and CIP spray ball assemblies enhance functionality and cleanability.
Design Requirements
Our designs incorporate seal-welded tube-to-tubesheet joints, sanitary tri-clamp fittings, polished surfaces, and compliance with 3-A Sanitary Standards and ASME BPE. Gasket materials like PTFE or Viton ensure compatibility with sanitary processes, while CIP compatibility simplifies maintenance.
