Chilling equipment for process fluids (water, glycol / water) designed to guarantee high energy savings of up to 80% as compared to the version not featuring the ”freecooling” system.
Series “RW CW” liquids chillers. Condensation by water supplied externally.
These process fluids (water, glycol / water) air condensed chillers are based on the compression of environment-friendly gas. They allow to obtain temperatures of the chilled liquid between +1°C and +20°C. Standard units operate at a +40°C maximum room temperature, whereas the “RW ax/HTA” version is designed to operate at higher room temperatures. This system allows considerable savings on heating costs. The IP54 protection degree is guaranteed as standard and allows outdoor installation without need for roofing.
This microprocessor allows to select and display the chilling liquid’s outlet temperatures. The microprocessor visualises the pressure of the chilling gas and allows remote diagnostics in case of failures (also by serial connection). It automatically operates the compressors on a turnover basis and controls partial their operation as a function of the work load. The standard version is equipped with alpha-numeric display showing the unit’s status.
