Heat exchanger

A heat exchanger in aquaculture is a device used to transfer heat between two fluids without mixing them, allowing the heating or cooling of water in tanks or farming systems. It helps maintain water temperature efficiently while optimizing energy consumption.

How It Works

The heat exchanger typically consists of high-conductivity metal plates or tubes:

• A hot fluid (e.g., water heated by a boiler or heat pump) circulates on one side.

• Aquaculture system water flows on the other side.

• Heat is transferred through the metal surfaces without fluid contact.

• The system is reversible and can also be used for cooling.

Advantages in Aquaculture

• Precise and stable temperature control.

• Water quality is preserved (no fluid mixing).

• Lower energy costs, especially when combined with renewable heat sources.

• Compatible with closed-loop systems (RAS).

• Versatile: works for both heating and cooling.

Common Applications

• RAS systems (Recirculating Aquaculture Systems).

• Aquaponic greenhouses or covered tanks.

• Temperature-sensitive species (tropical fish, juveniles).

• Integration with geothermal or heat pump systems.
