Sanitary Tubular Heat Exchangers - FANPOD Engineering

SANITARY TUBULAR HEAT EXCHANGERS

The Ultimate Solution for Challenging & Viscous Fluids

In the food, dairy, and pharmaceutical industries, processing highly viscous fluids or products with suspended particles requires specialized equipment. FANPOD engineers sanitary Tubular Heat Exchangers featuring a completely dead-leg-free design. By utilizing advanced corrugated tubes, our systems generate intense turbulence to maximize heat transfer while providing a continuous self-cleaning effect, ensuring strict hygiene and preventing product burn-on.

Key Sanitary Advantages & Capabilities

Engineered for strict hygiene, zero clogging, and maximum thermal efficiency.

Corrugated Tube Technology

Specially formed tubes disrupt linear flow, creating severe turbulence that dramatically increases heat transfer efficiency.

Continuous Self-Cleaning

The turbulent flow creates a natural CIP (Clean-In-Place) effect, preventing fouling and product scorching on the tube walls.

Viscous & Pulpy Products

Unmatched open-flow paths designed specifically for heavy pastes, sauces, and juices containing large fruit particles.

Absolute Hygiene

A fully sanitary design featuring no rubber gaskets in the product's heat-transfer path, eliminating contamination risks.

Easy Visual Inspection

Smart structural layout allows for rapid dismantling and full visual inspection of the inner product tubes to guarantee sanitation.

Decades of Lifespan

Constructed with thick, premium stainless steel tubes, ensuring exceptional durability and long-term reliable operation.

Overcoming the Limits of Plate Heat Exchangers

"While plate heat exchangers are excellent for thin fluids, they frequently clog when processing pulpy or high-viscosity products."

When processing materials like tomato paste, ketchup, fruit purees, or heavy dairy desserts, standard equipment fails. FANPOD’s sanitary tubular designs mitigate these risks entirely. The open channels ensure smooth processing of large particulates, preserving product integrity while maintaining the rigorous hygienic standards required for UHT milk and specialty dairy applications.

Structural Configurations

Tailored for Your Exact Product

Tubular heat exchangers consist of one or more inner tubes placed inside an outer shell. We engineer two primary configurations to handle varying viscosities and particle sizes:

  • Tube-in-Tube Design: The simplest structure with one inner tube and one shell. Ideal for products containing very large particles, offering a completely unobstructed path.
  • Multitube Design: Multiple small tubes (Tube Bundle) inside a larger shell, creating a high heat transfer surface area suited for medium to high viscosity fluids.
  • Zero Dead Zones: Both designs are completely sanitary with no dead-legs for bacterial growth.
Food Industry Processing

Specialized Applications

Food, Dairy & Pharma Focus

Our sanitary tubular heat exchangers are specifically deployed where conventional heat exchangers struggle. They provide gentle, highly efficient thermal treatment across multiple sectors:

  • Pastes & Sauces: Perfect for pasteurization and cooling of tomato paste, ketchup, mayonnaise, and mustard.
  • Juices & Concentrates: Safe processing of fruit purees and juices with fruit bits without crushing the particles.
  • Complex Dairy: Reliable performance for UHT milk systems, strained yogurt (Kashk), dairy desserts, and heavy creams.
