Sparkling water represents an increasingly interesting market niche with great potential in countries such as Germany, Italy, France, Sweden, Switzerland and Austria. Cosmetal, of Recanati, Italy, has always manufactured sparkling water models and continues to develop and find solutions that will improve its water coolers in every way. The company recently modified its product models marked WG (i.e., that dispense sparkling water) by introducing the cold water thermostat sensor in the actual carbonation device.
