RW

Axial centrifugal fans

Certificazione-IQNET    Certificazione-SQS

Closed-circuit, indirect exchange liquids chillers operating with water or a glycol/water mixture and employing the ambient air as cooling fluid.

A careful selection of the exchange batteries allows to obtain process fluid temperatures nearing the sucked air temperature.

Series “RW” Liquids Chillers Air condensation by centrifugal fans.

Process fluids (water, glycol / water) air condensed chillers 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/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. In case of indoor installation air channels for conveying the exhaust hot air can be installed and operated thanks to the centrifugal fan/s

Control Panel

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 their operation as a function of the work load. The standard version is equipped with alpha-numeric display showing the unit’s status.
