SwimTunnels.com produce and sell Steffensen-type swim tunnels for different reasearch projects ranging from measuring oxygen consumption of exercising fish at different swimming speeds, to exposing mussles or corals heads to controlled water velocities up to about 150 cm.sec-1
Currently SwimTunnels.com produce and sell 4 standard models 5, 8, 10 and 30, referring to the total volume of water in the swim tunnel, which will accomodate fisk from about 50 grms to about 1 kg. In addition SwimTunnels.com sell a small Blazka-type swim tunnel that can be used for zebrafish and similar size and shape fish. The four standard Steffensen-type swim tunnels are contructed for identical motors and motor controllers from the company SEW Eurodrive, and you can purchase the swim tunnels with or without motors and motor controllers. This means that you don't need to purchase 4 different tunnels with 4 motors, but can purchase 2 - 4 tunnels and just one motor, or even no motor, and either use you own motor or purchase one directly from SEW Eurodrive. We will supply yo with information concerning motor and frequency inverter model and a wiring diagram.
We do not produce or sell anything else but Steffensen-type swim tunnels and flumes, and the motor if requested, but will be happy to advice you concerning additional equipment you may need, .e.g.
In addition we will provide you with information like:
SwimTunnels.com is a spin-off project based on 30 years of research with exercising fish primarily carried out at Zoophysiology, University of Aarhus and the Marine Biological Laboratory, University of Copenhagen, Denmark.
