Thermal control in RAS systems is a key function for optimal growth, metabolic activity, and survivability during maturation, spawning, grow out and brood stock maintenance.
To achieve thermal control, heating (heat pumps & hydronic boilers) and chilling (DX chillers & hydronic chillers) systems are an integral part of RAS architecture. This equipment can be deployed in multiple configurations to control temperature for induvial tanks or across entire systems.
Heating and chilling equipment must be sized to properly offset the heat flow due to the ambient environment (evaporation, convection, conduction, and solar irradiance) as well as mechanical, biomass and filtration thermal loads that appreciably affect the temperature of an aquaculture system. By understanding how heat flows through a RAS application, a properly sized and selected heating and chilling system will enable the grower to achieve the desired system temperature year-round in an energy efficient manner. Stable and controlled temperatures directly contribute to regular and increased production.
