Blower units and aeration membranes

A total of four KUBÍČEK Roots blower units, type 3D28C-080K, were installed in spring 2022 to ensure the operation of the Danish-type recirculating aquaculture system. The complex of experimental and rearing tanks consists of six smaller tanks of external dimensions 7 x 4.5 m and one large tank of 15 x 4.5 m, total volume 250 m3.

According to the design calculations of the maximum air pressure requirement for optimal operation of the RAS, a maximum of two blowers will be in operation during the peak breeding season and two are prepared as backup.

By replacing the originally installed side-channel blowers, with new air sources, immediate 50% reduction in the energy consumption of the operation was achieved.

In addition, the customer operates the plant in conjunction with photovoltaic panels which, under optimum conditions, supply approximately 30% of the monthly energy consumption.
