Double-pipe / Multi-tube Heat Exchanger

·Modular Structure: Tube sections can be arranged in series or parallel to adapt to different heat loads and installation spaces.
·Easy Disassembly: Tube sections can be split for convenient cleaning and maintenance, reducing the impact of fouling.
·High Adaptability: Can handle media with particles or high viscosity, reducing clogging risks.
·Hygienic Design: Dead-leg-free flow channels support clean-in-place and meet food production requirements.

·Structure Form: Double or multi-layer concentric tube structure, supporting single-pass or multi-pass arrangements.
·Contact Material: Inner and outer tubes made of food-grade stainless steel 304/316L.
·Connection Methods: Supports various interface forms such as flanges and quick-clamp connections.
·Flow Direction: Supports parallel or countercurrent flow, adjustable according to heat transfer requirements.
·Cleaning Methods: Supports disassembly cleaning and clean-in-place (CIP).
·Applicable Conditions: Adapts to high-viscosity, particle-containing media and hygienic production scenarios.
·Single-tube, large-diameter design—highly efficient and convenient: The system features a single large inner tube, resulting in an extremely simple structure. Installation and maintenance are quick and easy, significantly reducing costs while providing efficient and stable heat exchange support for production.
·Suitable for High-Viscosity Media – Smooth and Reliable: Designed for high-viscosity materials, it features low flow resistance and is resistant to clogging, ensuring a stable and smooth heat exchange process that meets the demands of various high-viscosity operating conditions.
·Slight Heat Distribution Variation: There may be slight variations in heat distribution at the center of the material flow; however, under normal operating conditions, this has minimal impact on overall performance and still ensures high-quality heat exchange for most production processes.

·Food and Beverage: Pasteurization, cooling, and holding processes for dairy products and juices.
·Chemical Industry: Heating, cooling, and heat exchange of high-viscosity process media.
·Pharmaceutical Industry: Heating, sterilization, and cooling processes for pharmaceutical liquids.
·Industrial Heat Exchange: Heat transfer processes for media containing impurities or prone to fouling.

·Reduced Heat Exchange Efficiency with Non-compliant Media Outlet Temperature
Check fouling on inner and outer tube walls; confirm stable media flow and pressure; verify tube section arrangement and flow direction meet design specifications.
·Clogging on the Media Side
Disassemble tube sections to remove residual materials or impurities; adjust media flow rate; verify particle content in the media does not exceed the equipment's processing range.
·Leakage at Connections
Check if connection gaskets or seals are aged; confirm tube section alignment; re-tighten connections according to specifications.

·Ensure aligned tube sections and properly installed seals during installation to avoid leakage due to misalignment.
·Gradually increase pressure and temperature before operation to avoid sudden changes affecting seal performance.
·Regularly disassemble tube sections for cleaning to remove internal fouling and residual materials.
·Drain media inside the equipment during long-term shutdown to prevent pipeline freezing or corrosion.
