SANITARY TUBULAR technology
Sanitary Tubular Heat Exchangers
Hygienic tubular heat exchangers for clean, viscous, fibrous, particulate or fouling products in food, beverage, dairy and pharmaceutical processing.
Working principle
How the technology transfers heat.
One product stream flows through smooth or corrugated inner tubes while the utility fluid flows through the surrounding shell. The separated circuits transfer heat indirectly, and the tube geometry can be selected to keep viscous or particulate product moving with a manageable pressure drop.
- Construction

- Ra ≤ 0.6 μm; typical 0.4 μm
- Published external surface roughness
- Ra ≤ 1.0 μm; optional
- Polishing
- Mechanical polishing or electropolishing
- Connection options
- TC Tri-Clamp and SMS sanitary unions
Engineering explained
See what is happening inside the exchanger.
Product imagery is paired with technical context so buyers and engineers can understand construction, flow path and configuration—not just the exterior.
Separated sanitary product and utility circuits
The original HEXNOVAS product drawing identifies the heat exchanger sections, stainless support frame, adjustable feet, product inlet and outlet, and hot-water connections.
Modular frame and optional stainless case
The modular tubular bank is supported by a stainless frame and can be supplied with a 304 stainless case; thermal insulation is available when required.
Connection configuration
Sanitary union connection options
Choose the hygienic union standard that matches the process line and cleaning procedure.
- TC Tri-Clamp sanitary union
- SMS Swedish Metric Standard union
- Project-specific hygienic connection size
- Polished stainless product-contact surface
Material compliance
Hygienic construction for food-grade processing.
Product-contact construction can be supplied in SS304 or SS316L, with smooth crevice-conscious surfaces selected for repeated cleaning. The support frame and optional insulated case are available in SS304.

Frequently asked questions
Key questions before product selection.
How does Sanitary Tubular Heat Exchangers work?
One product stream flows through smooth or corrugated inner tubes while the utility fluid flows through the surrounding shell. The separated circuits transfer heat indirectly, and the tube geometry can be selected to keep viscous or particulate product moving with a manageable pressure drop.
What information is required to select the right product?
Provide product composition, viscosity, particle or fiber size, flow rate, temperature program, allowable pressure drop, CIP procedure, materials, surface finish and sanitary connection standard.
Which materials and configurations are available?
