Public Aquariums have seen major changes in animal collections over the past thirty years. Gone are the days of just displaying finish and invertebrates. With an increase in collection diversity comes the need for diversity with regards to life support systems, (LSS). As this industry has evolved, so too has RK2 Systems. While we are extremely proud to be the number source for protein fractionators worldwide, we have expanded our equipment line up to provide the same performance and reliability facilities have counted on time and time again.
