Innovative Marine is proud to introduce HELIO, our new line of heaters utilizing ultra-safe PTC (positive temperature coefficient) technology. Up until now, the way we chose to heat our aquariums have been electric immersion heaters that use resistance wires as the primary source of heat. This is the same technology commonly used in toasters. When these types of aquarium heaters are exposed to air or become covered with debris, the heat is unable to dissipate quickly enough resulting in a rapid temperature spike, reduction in operation life and eventually catastrophic failure of the aquarium. When developing the HELIO, we looked at the aquaculture industry and how PTC technology was utilized. After scrutinized detailed analysis, we extrapolated how to efficiently heat (in both cost and thermal dispersion), as well as minimizing the danger of air exposure and for everyday use. PTC technology utilizes solid state ceramic chips that are programmed to reach only a certain predetermined set temperature. As compared to resistance wires that continuously increase in temperature until the element ceases. After years in development, the HELIO heating system possesses powerful features that exceed current reef aquarium heater expectations and achieve three main objectives: Increased safety. Improved reliability. And to provide a new reef aquarium heating technology superior to the long held standard. HELIO PTC Titanium Heating System. Safe. Stable. Smart.
