Cascade Celesti Duojack Solar water heater has greater pressure withstanding capacity with its heavy-duty tank and can operate at maximum pressure of 6 Kg/cm². Custom designed tanks can also operate with much higher pressure.

Life of the system is enhanced in areas, prone with hard water. These systems are suitable for feed water with PPM above 200 and upto 1900 and can operate in pressure condition
