SweetwaterŽ Heat ExchangersWe developed these "shaped" aluminum coil heat exchangers just for use in aquaculture. Simply connect the coils to a heated or chilled source-a solar or gas heater, ground water or even a fireplace-and drop the coil into the tank or pond. These heat exchangers will isolate the pumped fluid (containing antifreeze, copper or other potentially toxic fluid) from the culture water. Be sure to include an expansion tank, air separation valve and water replacement feed valve.
The pumped fluid gives up its heat over less coil length, due to the turbulence imparted by the convoluted surface of the pipe. Our "shaped" tubing also allows easy bending to fit the application (placing the exchanger in an area of good water movement will improve heat transfer).
These low-cost, aluminum heat exchangers will do a fine job in both temporary and low-corrosive applications. TDH resistance is the total dynamic head pressure at the flowrates shown. For higher flowrates order two or more and operate them in parallel. Be sure to use a sacrificial anode in corrosive liquids. Made in USA. |
