RAS modul 4T

It is complete recirculation aquaculture system that is designed for everyone. It can be used in the proffesional fish farming or in hobby fish farming too. RAS Modul ca be used as a “fish” part of an aquaponic system also. It is ideal as pilot project for aquaculture begginers or for the RAS investors, who want to try small-scale fish farming before bigger investment.

Our RAS modules are easy to install easy to operate and easy to maintain.

For more informations about our RAS modules dont hesitate to contact us, we looking forward to your inquiries
