AquaCal of St. Petersberg, Fla., uses Thermo-Link

— the patented Titanium heat exchanger technology used exclusively in AquaCal

heat

pumps.

The primary cause of premature heat pump demise is the failure of the heat exchanger. Ordinary heat exchangers are made from a cupronickel alloy. This cupronickel material is susceptible to attack from the sanitizers used in pools and spas, and from other related water chemistry conditions. Once the heat exchanger fails, the heat pump is ruined.

The ThermoLink

Heat Exchanger tube is made from titanium, and is virtually impervious to water- chemistry damage. For more information contact, AquaCal, 2737
