Puretec SPARQ S4 filtered ambient, sparkling & chilled undersink system gives you the luxury of filtered sparkling or still water right in the heart of your home. A simple touch on the stylish LED panel will give you filtered sparkling or still water, chilled to perfection. With sleek lines, elegant styling and the luxury of sparkling water on tap, it is the perfect finishing touch to your kitchen or entertaining area. Using the latest carbon briquette technology, the filtration system will purify the water in a multi-stage process. Puretec’s long life filters usually only require changing once every 6 to 12 months. Carbonation system Once the water has been purified, it can be delivered either sparkling or still. If sparkling water is selected, the system injects CO2 gas into the water stream as it is dispensed. This gives you chilled, fresh water with just the right amount of sparkle. The CO2 canister is easy to replace, and usually lasts between 9 to 12 months, depending on individual use. Chilling the water A built in cooling system that chills the water for a refreshingly cold drink, you can choose between ambient or chilled when dispensing still water. The sparkling water is delivered chilled only.
