FPC (Flat Plate Collector)
Solar Water Heater


A highly efficient special water heating system that comes pre-loaded with a 'heat-exchanger' and is highly durable against monkey menace.


The FPC system uses Copper tubes with Copper fins ultrasonically welded on to them to ensure maximum heat transfer. These copper tubes are assembled into a Collector box and covered with a Tempered Glass to give better efficiency and durability. Our Collectors come with 99.99% pure Copper and are of the highest standard in the industry.

Sizes Available

Available in any Capacity
Salient Features
Copper Tubes of highest standard
  • Because of superior conductivity of copper, the water gets heated to high temperatures
  • Availability of hot water even on partially cloudy days
Laser welding of collectors
  • Achieves superior conductivity, enhances reliability
Anti-condensation system
  • Prevents condensation of vapour within collectors and avoids corrosion.
  • Increases efficiency and life of water heater
PUF Insulation
  • Ensures that the heat generated by the water heater is retained for long hours
  • Sizzling hot water is available next morning
Ladder & cage type heat exchanger
  • Helps in superior heat exchange cycles which result in better heat transfer
  • Ensures higher temperature of hot water
SS304 heat exchanger element
  • Offers high corrosion resistance and ensures long life of the heat exchanger and the system
Heat Exchanger

In a Heat Exchanger system Propylene Glycol is passed through a coil which indirectly heats the water in the tank. This ensures no scaling, thus low maintenance and longer life of the SWHS irrespective of the water quality. This also ensures efficient working of the system even in sub zero temperatures.
