Evaporators / Condensers SonFlow SFC501 & SFC801

SonFlow Condenser/Evaporator units are plate heat exchangers designed for low-pressure steam condensation and evaporation applications. They are suitable for processes with significant temperature differentials between the hot and cold sides, requiring large steam inlet cross-sections and controlled pressure drop.

Condensation Operation

The asymmetric design features a large steam inlet and smaller connections for cooling water and condensate. This ensures proper steam distribution across the plates and stable condensate removal without a welded plate pack.

Applications

Typical uses include:

• low-pressure steam condensation,
• evaporation in food, sugar, and alcohol processes,
• biogas and heat recovery,
• pulp and paper, mining, chemical, and petrochemical industries.

Technical Selection Data

Key specifications:

• models: SFC501 and SFC801,
• design pressure: 0.6 MPa,
• design temperature: 180 °C,
• available large connections up to DN1000,
• suitable for CIP cleaning,
• capable of cleaning both circuits as plates are not welded.

Sizing Considerations

Selection requires steam supply or evaporation load, inlet/outlet temperatures, steam pressure, available cooling water, allowable pressure drop, fouling tendency, and CIP requirements. Gasket selection should be verified based on temperature, cleaning chemicals, and product composition.

FAQ

When to choose over conventional plate exchangers?
When low-pressure steam, large temperature differences, or large steam inlet requirements exist.

When is more frequent cleaning needed?
For products with organic solids, sugars, salts, or biological load.

What to request at the procurement stage?
Thermal sizing, plate materials, gasket material, connections, CIP program, and pressure certification per project.
