Description
The Deema Series is Dawtec’s next-generation thermosiphon solar water heater, marrying the high-gain performance of vacuum tubes (> 92% absorption, > 68% efficiency) with the robustness of closed flat-plate technology. Its minimal-maintenance, passive circulation design supports up to 6 bar working pressure and offers a 20-year life expectancy. Two chassis options—standard galvanized steel or premium stainless-steel (316L)—protect a polyurethane-insulated tank, while ALN-CU absorbers maximize heat capture. Available in six models (150 L to 300 L), each unit can reduce conventional water-heating energy use by up to 85%. Backed by a 5-year warranty and designed for seamless architectural integration, Deema delivers reliable hot water with sustainable, green technology.
