Sondex S22FG10 Plate heat exchanger

• Used for efficient heat transfer between two fluids in various industrial processes.
• Commonly applied in HVAC systems for heating or cooling.
• Utilised in food and beverage processing for pasteurisation, sterilisation, or cooling.
• Found in chemical and pharmaceutical industries for process heating or cooling duties.
• Employed in energy recovery systems to improve overall plant efficiency.

Typical capacity

For this class of equipment, capacities commonly range from 100 kW to several megawatts, depending on plate count and fluid properties.

Plate material

Units of this type typically feature stainless steel plates (e.g., AISI 304, 316) suitable for a wide range of media.

Gasket material

Common gasket materials include NBR, EPDM, or Viton, selected based on temperature and chemical compatibility requirements.

Maximum operating temperature

Plate heat exchangers typically operate up to 150°C, with specific limits depending on gasket and plate materials.

Maximum operating pressure

Operating pressures commonly range from 6 to 25 bar, varying by design and plate thickness.

Footprint

Plate heat exchangers are known for their compact design, offering a high heat transfer area within a relatively small footprint compared to other exchanger types.

Maintenance requirements

Routine maintenance typically involves periodic cleaning of plates and inspection/replacement of gaskets, depending on process fluids and operating conditions.

• What are the main advantages of a plate heat exchanger over a shell and tube exchanger?

  Plate heat exchangers typically offer higher thermal efficiency, a more compact footprint, and easier maintenance due to accessible plates. They are also more flexible for capacity changes.

• Can this unit be used for viscous fluids or fluids with particulates?

• What is involved in cleaning a plate heat exchanger?

• How do I determine if this heat exchanger is appropriately sized for my application?

• Are spare parts readily available for Sondex plate heat exchangers?

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.
