 Flate Plate Collector Type System - TECHNOLOGY: Thermosiphon/ Forced circulation type closed loop systems are designed for producing heat from solar energy. The thermosiphon is a passive design, which allows heat transfer using natural convection ideally in a vertical heating system. Solar fluid (water + Glycol) remains in closed loop.

After getting heated in the solar panel it rises to outer jacket of tank and transfers the heat to the stored water in the tank before finally returning to lower side of solar panel for renewed absorbtion of solar energy.

The advantage is that it avoids using the conventional pump, which keeps the complexity and cost of thermosiphon system low at the same time ensure that the panel tubes always remain clean inside and for efficient heat transfer.

Whereas forced circulation closed loop systems use a small solar control station which includes a low power high efficiency pump with motor to circulate the solar fluid from

the solar panel to heat exchanging coil inside water storage tank.This enables to locate the water tank anywhere lower or higher and at any distance from the solar panel giving lot of flexibility of locating the tank. It also helps to increase the efficiency of heat transfer between the solar, fluid and water to be heated.

We also provide an expansion tank in the solar fluid circuit to take care of expansion/ contraction of the solar fluid due to rise/fall in its temperature.

SOLWET systems are characterized by high- selectivity coated harp absorbers and tank sizes perfectly coordinated with the system, together with unique charging properties.

SOLWET closed loop solar water heater are designed to achieve high temperatures up to 94°C and the tanks are designed to operated under pressure. The system is uniquely provided with a pressure safety valve for the closed loop fluid and a temperate and pressure safety valve in water circuit to open/drain at set temperature (94°C here) or at set pressure, whichever occurs.
