The series Sigma of Nova Frigo, company represented by C.T.Service-Centrotécnica, is formed by refrigerators of water of last generation, condensed by water totally autonomous with a complete hydraulics circuit, internal tank presurizado and electrobomba of circulation.
These refrigerators are units monobloque endowed of evaporador and condenser to plates that, thanks to his sobredimensionamiento, allow to the compressesor work in optimum conditions of high performance and low energetic consumption, even in extreme conditions of work. The particular technical conception of this team, absolutely silent and condensed by water, contributes to improve the environingingment of work since it does not offer acoustic pollution neither broadcast of heat or currents of air.
The team, in addition to generating cold water for refrigeration, is able to provide hot water to temper moulds, until 90 °C. According to the different versions and configurations of the models, can have of a circuit of cold water or of circuit of cold water (from –5 °C) more a second circuit of hot cold/water (from –5 °C until 90 °C) totally independent in regulation and control, until the most sophisticated team; that provides 2 circuits of hot cold/water (of –5 to 90 °C), also with control and gestión absolutely independent one of another. Simultaneously, of each one of the types exist different models regarding power of refrigeration and atemperación.
