Sealed high-borosilicate vacuum tubes capture solar energy with virtually no convective heat loss — delivering 70–90°C hot water every day, even on cloudy mornings and in low-light conditions. A gravity-fed thermosyphon design means no pumps, no controllers, and no recurring maintenance.

Because the vacuum-tube collectors handle scaling far better than flat plates, ETC systems thrive in hard-water regions up to 3000 PPM — making them the dependable choice for most Indian households.

Toughened frosted glass at 97% transmittance sits above a copper-riser absorber sheet, ultrasonically welded along its entire length for maximum heat capture and zero hot-spots. Engineered to perform reliably in direct sunlight, FPC delivers 70–90°C daily at scale.

Available in both pressurised (3 kg) and non-pressurised variants, FPC is the right choice when the system needs to feed pressurised plumbing — apartments, hotels, hostels, and commercial buildings — and where the local water is soft (under 200 PPM).
