Your specialist in design and construction of Recirculating Aquaculture Systems (RAS)


Heating and Cooling

Fish only grow fast and with a low FCR at a species-specific bandwidth of temperature. Keeping fish at a temperature that is 1 °C above or below the optimum temperature can already result in a reduction in growth rate of 5-10%. 

A major advantage of recirculating and reusing the water is that it becomes economically viable to heat or cool the water. Of course, this assumes the RAS is housed in an insulated building and the heat exchangers are used on the inlets and outlets of air and water. 

To be able to farm fish in a wide variety of places with the smallest energy input as possible, knowledge of climate control is of utmost importance. For this purpose, ACE developed their own air to air and water to water heat-exchangers. This heat-exchangers differ from the widely available heat-exchangers that they won’t easily clog and are built with non-corrosive material. By means of the counter flow principle up to 90% of the energy could be maintained.
