Adiabatic Cooling Treatment

• The key advantage that this system brings is the reduction in energy costs due to the lowering of the discharge pressures. Studies have shown that a 10-degree reduction in air temperature can lower the power consumption by 12 – 14%

• Frequent plat tripping when the ambient temperature peaks can be avoided leading to higher system reliability and availability

• The screen help protects the cooling coils from direct sunlight and atmospheric

• Opportunity to use same system for enhanced cooling requirement due to the increased operating range. This enables savings on sizing of the system.
  Some of the drawbacks of the precooling system which prevent the technology to be used in all installations are

• Requirement of treated water is the most critical aspect as the nozzles on the jet have very fine tolerances. Thus, water with the right quality of hardness is essential which requires a water treatment system to be installed

• To prevent legionella disease, the water requires to be treated. This is usually done by UV systems and again increases the complexity of the system.

• The cost of maintenance increases due to the added systems and pumping components. This negates the lower maintained effort of air cooled chillers

• Water usage while low, brings in added complicity into a traditionally less complex system as compared to a water-cooled chiller system

• The control systems are complex and hence will increase the cost as well maintenance efforts.

Thus, the choice to go for a precooling system depends on a various factor not only the initial cost benefits and each application requires a deeper study to arrive at the best possible opti
