Water Heat Exchange Unit

• Maintaining precise water temperatures for jacketed vessels in brewing and dairy.
• Controlling process water temperature in confectionery and bakery production.
• Pre-heating or cooling water for CIP (Clean-in-Place) systems.
• Temperature regulation for blanching and pasteurisation processes.

Typical capacity

For this class of equipment, thermal capacities commonly range from 10 kW to 100 kW, depending on the specific model and application.

Power supply

Units of this type typically operate on 3-phase industrial power, commonly 400V, 50Hz in the UK, with varying amperage requirements.

Temperature range

Water heat exchange units are generally designed to control temperatures from approximately 5°C to 95°C, suitable for a wide array of food processing tasks.

Heat transfer medium

These units primarily use water as the heat transfer medium, often with glycol for lower temperature applications or to prevent freezing.

Connections

Commonly found with standard industrial flange or threaded connections, typically ranging from DN25 to DN80, for integration into existing pipework.

Control system

Units typically feature a control panel with a PID controller for precise temperature management, often with digital displays and safety interlocks.

• What is the primary function of a water heat exchange unit?

  Its primary function is to accurately control and maintain the temperature of process water, either heating or cooling it, for various industrial applications.

• How does this unit differ from a chiller?

• What maintenance is typically required for this type of equipment?

• Is this unit suitable for direct food contact?

• What factors should I consider when sizing a water heat exchange unit?

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.
