Adiabatic cooler /Dry coolers
Adiabatic cooling is the process of reducing heat through a change in air pressure caused by volume expansion. Working in wet mode for typically only 3% of the year, adiabatic systems consume around 1% of the water used in traditional cooling towers and as little as 2% of that used by wetted surface hybrid dry coolers. They automatically spray, purge, drain down and UV sterilise when required - water is only evaporated when dry cooling alone can no longer achieve the required water temperature.
As a society, now more than ever, companies are being challenged to address climate change. With the industry already facing scrutiny over carbon emissions and energy consumption, water scarcity is poised to be the next major resource to be publicly examined.
Global warming is therefore forcing us to question the methods traditionally used in cooling. Systems such as cooling towers which are inherently inefficient and expensive to run, are also renowned for consuming millions of litres of water.
Cooling towers use their fan(s) and fill pack to evaporate water and produce circa. 30°C process water. While effective at providing cooling, it uses a lot of water and requires water treatment to control biological growth. Cooling towers also expose the process water to the atmosphere and then require constant filtering.
Adiabatic Coolers offer a modern alternative to cooling towers, delivering impressive energy and water savings alongside significantly lower maintenance and OPEX. They offer a modern, low risk alternative to hybrid and traditional cooling towers; UV sterilisation systems come as standard.
Key benefits include:
-Best combined PUE (power usage effectiveness) and WUE (water usage effectiveness) delivering impressive energy and water savings
-A larger number of smaller fans provide considerably higher resilience in the event of a fan failure
-No weekly/monthly health checks required
-No specialist maintenance contract required for bi-annual strip down and rebuild with chemical cleaning
The peculiar V-shaped structure of HACST Gas Cooler allows to make the most out of the adiabatic system and reduce the overall dimensions of the installation.
These units with the option of adiabatic air cooling allow an efficient operation even in regions where the ambient temperature could exceed 40 ° C, reducing the blocking chance of the refrigeration systems, commercial refrigeration (supermarkets) and industrial refrigeration (production, packaging and distribution).
The control panel developed for the management of the adiabatic system continuously adjusts the flow rate and consequently minimizes the water consumption based on the load request of the heat exchanger, the adjustment is based on the working speed of the electronically commutated motor fans, the factory parameters can be modified to adapt to different operating conditions and system needs (water saving / energy saving).
The cleaning system is available on request on all V-type units: a specific piping with two ramps per row with specific nozzles to wash the heat exchanger under pressure. The system allows the washing of the dirt accumulated on the finned pack from the inside towards the outside of the finned pack.
