When investing in solar technology, it is important to ensure the “engine” you select is the most powerful and the longest lasting made. This if why we use SunRain’s patented “3-Hi” vacuum tubes. The absorbing coating found on the inner layer determines how efficient the vacuum tube will operate. The method and material of this coating will also define the life expectancy of the vacuum tube.

Most solar vacuum tubes use a hi-tech reactive sputtering process to coat the inner tube. Most commonly this coating is made from an aluminum and aluminum-nitrogen coating (Al-N/Al) which is the primary absorbing coating.

sunrain vacuum tube solar heatersSunRain’s International patented interference film coating 3 Hi” vacuum tubes use 3 systems to ensure the most effective heat absorption. This included a AL-N/AI layer but also a separate aluminum and copper layer. The added layer conduct heat better and also stabilize the coating allowing for a much longer lifespan of 20 year or greater.

Test Drive one of our solar heating systems and you will quickly see the difference a powerful “engine” makes. See below for comparission on SunRain performance vesus other leading evacuated tube suppliers.
