Case Study

Gospodarstwo Rybackie Łupawa (GRL), one of Poland’s leading trout farming and processing companies, selected Robuschi’s Robox blower units to support its expanding aquaculture operations. The blowers are used for tank aeration, water movement, and biological filtration—three core processes in recirculating aquaculture systems (RAS).

The Challenge

GRL needed a reliable, scalable solution to support its growing production capacity and meet strict quality standards. With two facilities—Zochowo (outdoor) and Nowina (indoor)—the company required equipment that could handle high oxygenation loads, maintain water circulation, and support biological filtration, all while operating efficiently and quietly.
