Replacement of evarorative cooling tower
A huge amount of fresh water is consumed every day because of the use of traditional evaporation systems for heat dissipation in industrial processes (cooling towers). Growing water scarcity, difficulties in finding it and ever-increasing costs are pushing the industry towards this new technology that is able to save up to 95% of water: adiabatic cooling. This technology also provides higher efficiency in heat transfer, reduced maintenance and complete absence of pollutants.
WHAT IS ADIABATIC COOLING?
It is a water cooling system using a closed ambient air circuit that combines:
- Finned water packaging – to – air heat exchanger (cooler)
- Axial fans for forced air convection
- Adiabatic system for pre-cooled air in hot weather
- System management monitoring equipment
HOW DO ADIABATIC COOLERS WORK?
It has 2 working modes:
1. ‘Dry’ mode.
• For most of the year, the unit operates as a classic dry cooler without water consumption and the heat transferred by the water is dissipated into the ambient air by convection of the air forced by the fans.
2. ‘Adiabatic’ mode
• The adiabatic mode is automatically activated during periods of high ambient temperature and only when the dry mode is not sufficient to maintain the outlet water temperature within the preset maximum set value. Before entering the laminated heat exchanger, the high-temperature ambient air passes through an ‘adiabatic chamber’ (patented) where moisture is added and it is subsequently precooled. In this case, the control system continuously regulates the amount of evaporated water only when necessary to maintain the desired set value.
