Sondex S22FG10 Plate heat exchanger

• Heating or cooling of liquid food products such as milk, juices, and sauces.
• Pasteurisation and sterilisation processes for beverages and dairy.
• Heat recovery in various food processing lines to improve energy efficiency.
• Chilling of products post-processing before packaging or storage.
• Use in Clean-in-Place (CIP) systems for heating cleaning solutions.

Typical capacity

For this class of Sondex S22FG10 plate heat exchanger, capacities commonly range from 500 kW to over 1 MW, depending on the number of plates and application.

Plate material

Plates are typically constructed from stainless steel (e.g., AISI 304 or 316) suitable for food contact and corrosion resistance.

Gasket material

Common gasket materials include EPDM or NBR, selected based on temperature, fluid compatibility, and food safety requirements.

Maximum operating temperature

Units of this type commonly handle temperatures up to 150°C, though specific limits depend on gasket material and design pressure.

Operating pressure

Typically designed for operating pressures up to 10-16 bar, depending on the specific model and plate thickness.

Footprint

The footprint is relatively compact for its capacity, typically requiring around 1-2 square metres of floor space, plus access for maintenance.

Maintenance requirements

Regular inspection of gaskets and plates is required, with periodic cleaning and potential gasket replacement depending on operating conditions.

• What are the primary benefits of a plate heat exchanger for food processing?

  Plate heat exchangers offer high thermal efficiency, compact design, and flexibility for capacity expansion. They are also easy to clean and maintain, which is crucial for hygiene in food applications.

• Can this unit be used for both heating and cooling applications?

• What considerations are important when installing a used plate heat exchanger?

• How do I determine if the Sondex S22FG10 is suitable for my product?

• What spare parts are typically needed for ongoing operation?

Heat exchangers are considered reliable workhorses in food processing operations. Buyers typically value their efficiency in temperature control and consistent performance across production runs. When purchasing used units, inspectors should examine gasket and seal condition, check for corrosion or scaling inside tubes, and verify maintenance history. Industry sentiment favours models from established manufacturers with proven track records. Key strengths include durability when properly maintained, relatively straightforward repairs, and compatibility with existing systems. Buyers often prioritise plate and frame designs for their flexibility and ease of cleaning.
