Flat Plate Industrial Solar Water Heater

We are the largest manufacturer and supplier of Flat Plate Industrial Solar Water Heater in Delhi, India. There are two types of solar water heating systems, based on type of circulation;

1. Thermosyphon 2. Forced circulation

All domestic and industrial systems upto 4000 LPD (liters per day) @ 60 deg.C,; works on the principle of thermosyphon. Industrial systems beyond 4000 LPD to any capacity will work on forced circulation principle.

Thermosyphon system:
The system works on a principle called "THERMOSYPHON" (Natural circulation).Due to density difference between the cold & hot Water, the lighter hot water flows up into the tank and the heavier cold water enters the collector.

Solar radiation incident on the collector panels heats the absorber. This heat is transferred to the water contained in the absorber & becomes less dense than the water in the storage tank. Hot water starts rising and settles at the top of the storage tank. Simultaneously cold water descends to the collector absorber tubes, gets heated up and the cycle repeats.
