Case Study #14: AquaZoo
Initial situation
In public aquariums, many species of fish and anemones are highly sensitive to metal ions in their environment. Meanwhile, lighting and water circulation systems continuously add heat to the tanks. To maintain healthy aquatic conditions, both freshwater and saltwater systems must be carefully temperature-controlled, without introducing corrosive or toxic elements.
Challenge
Design a heat exchanger system that provides precise heating and cooling while remaining fully resistant to seawater and completely free of metal ion release. The system must also be adaptable to different tank designs and filtration setups.
Solution
Calorplast offers plastic heat exchangers made from polyethylene (PE) and PE-RT (polyethylene with elevated temperature resistance). These materials are seawater-resistant and completely non-metallic. Depending on the aquarium layout, Calorplast systems can be installed as:
-
Tube plate or tube bundle heat exchangers integrated into external circulation loops
-
Immersion-type heat exchangers placed inside service or filter tanks, with modular configurations tailored to each installation
Result
Calorplast PE heat exchangers have been successfully used in aquariums worldwide to maintain optimal water temperatures without the risk of metal ion contamination. Their long service life, resistance to corrosion, and modular design make them a trusted solution for aquatic environments.
