Within the last two years the experts of design center of NKNH and Polymerholodtechnica company have developed projects on replacement of existing wooden sprinklers ricks to polymeric.

New sprinklers and water-catchers have no analogues in the world . They issue by the American technology on thermoplast coproduction of Italy's and Japan's companies. Polymeric sprinklers are self-cleaning and they are not subject to pollution. They are delivered bring together and due to small weight they can be mounted on the facilitated constructions in a few hours. Their use is not only assurance of the stable technological mode of the ricks operation in summertime and the reduction of piling of the turnaround water-supply system equipment, but it is also improvement of operational characteristics of ricks: the increasing heat exchange, a hydraulic load, service life of sprinklers etc.

In addition, at the development stage of the project the problem to inhibit from frosting-up of ricks was solved. There are buffer "dry" sprinklers used for these purposes which are mounted on air intake windows.
