Piovan company represented in Russia by Solan-D Ltd. has worked out new compact and energy-saving water-cooling installations of CH series with cooling capacity diapason 6-600 kW. Water-cooling installations of CH series perfectly suit for cooling molds hydraulic systems of injection molding machines and blow-extrusion molding machines, thermoforming installations, casting forms, calanders, roller press. They may be also applied for supplying of cooling water to mechanic systems and many other equipment and devices in need of cooling water with tight temperature limit. Recently Piovan has released to the market a new model of water-cooler CH 1000 alongside with CH 1400 model of a larger capacity. The both models of cooling capacity 140 and 170 kW were designed to solve two special tasks: first of all, to extend model range of medium-sized refrigerators noticeable for their quality and reliability in order to satisfy various requirements to cooling of the most variable manufactures; secondly, to provide high productivity of compact machines proper. It could be achieved due to such new opportunities as inner hydraulic system made from a material deprived from iron, double inner stand-by, centrifugal ventilators, thermostatic electronic-controlled streamlined valve, due to which it is possible to achieve energy saving about 20 thousand kWt a year.
