Cascade Celesti Duojack Solar water heater are recommended for areas with hard water above 200 ppm and in pressurized application. Normal water that has very low PPM is used as heat transfer liquid in the solar collectors which transfers heat to storage tank. 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

Unique features:

stainless All Stainless Steel tank and support stand – unique to Cascade.
tank-cleaaning During operation solar water heater develops very high temperature and develops
deposits in the tank, this reduces circulation and directly affects the hot
water output over the years. Cascade’s tank opening option helps to easily remove deposits.
double Double jacket tank improves compatibility of the system with
very hard water up to 1900 PPM
medical Medical grade stainless steel provides hassle free long life
hotter-faster Cascade’s most efficient solar collectors and system design
delivers temperature 5 Deg hotter – Unique to Cascade
max-drop Just 1 Deg C drop till the last Ltr. Cascade’s Surge Management Internal
Circulation Design ensures hot water output at the same temperature till
90% of output and varies only 1 Deg from the last 10% output.
concealed Shock proof – as all electrical parts are built inside the tank and are
not exposed to rain as in other solar heaters
energy-saving Provision for electrical heater is placed in middle of the tank and hence
only partial capacity is heated up for back up. This saves
huge energy – Unique to Cascade
free-insualtion Hot water is used mostly in winter when sunlight is rare and solar heater
runs on electrical back up. In normal situation the hottest water remains
in the vent pipe and due to cold weather the temperature is wasted during night.
Cascade provides free insulation for vent pipes so that energy is saved – means extra savings.

service centers spread across the country.
