Generally there are refrigerating units for the production of glycol water to cover the process need and boilers to produce hot water. Chilled water, generally used for air-conditioning and for less-heavy process applications, is produced from glycol water using a plated heat exchanger. Refrigerating units have an heat condensing recovery system, partial or total according to the needs: this option allows to produce hot water avoiding thermal plant overloading. Hot water thermal level production through recovery system is about 45-50°C. The remaining quote is obtained with boilers and thermal level monitoring is made with a three ways modulator valve. The condensing heat that cannot be recovered is drained using an industrial hydraulic cyrcuit linked to a cooling tower. This tower is positioned over a catchment area, from which the pumps draw from the plant units and from the freezing sets. The central plant can be modified to insert steam boilers, diathermic-oil boilers, hydro-cooling plants, etc., according to production needs
