Carocell produces safe, high quality potable water from any source including seawater, groundwater and contaminated or polluted water. It also incorporates Zero Liquid Discharge (ZLD) technology when Carocell panels are in a series, which converts waste brine into drinking water and valuable fractionalized salts (sodium chloride and magnesium chloride – used for dust suppression in the mining industry).

Carocell is the most efficient and cost effective product of its kind. Preliminary independent testing by world-renowned engineering firm ARUP found Carocell to be almost twice as solar efficient as comparable products. When combined with ZLD, Carocell is also significantly cheaper than commonly used reverse osmosis technology.

Low cost, robust, modular solar panels can be ground or roof mounted. The design enables multiple panels to be connected together to produce larger quantities of distilled water from a single source. The panels can be supplied individually or in bulk. Single panels are ideal for family use, a series of panels will provide for a village or the panels can be set up as a large scale water farm. The unique design of carocell enables rainfall to be captured and harvested as well.

Carocell’s increased efficiency (65% with peak efficiencies above 80%) over other solar distillation products (30 – 40%) is a combination of the proprietary materials used to dramatically increase the temperature of the feed water on the solar collector which enhances the evaporation / condensation processes inside the panel.

Additionally, sophisticated geometrical design allowing for easy maintenance, optimum performance and a self-controlling natural convection loop enabling widely superior energy recovery. 

The system receives impure water through pump or gravity feed and disperses it evenly. Solar energy heats the water, it vaporizes and then condenses on the inside of the composite plastic panel enclosure. Droplets of distilled water run down into a pure water outlet at the bottom of the unit. Greater efficiency of purified water output has been achieved through the unique distillation system design.

The design includes composite layers of the water-tight panel enclosure and the surface treatment of the solar collector. As well as allowing the moist air to circulate the solar collector to produce condensate on the interior front and back surfaces of the enclosing panel.

Carocell panels are a breakthrough in Solar Desalination, providing:

• 55 – 65% efficiency solar energy to distilled water
• 50% more efficient than most comparable products
• 5 – 25% of the installed cost of comparable products

Carocell Direct Solar Desalination is a unique patented modular panel that has the capability of producing millions and millions of litres of pure distilled water per day. Alternatively Carocell - Direct Solar Desalination can be used for smaller domestic, rural and village applications.
