PreCooll — cut chiller energy 20–40% by cooling the air before it hits your condensers

Oxycom PreCooll adiabatic pre-cooling for air-cooled chillers, condensers and dry coolers: 15–25°C cooler entering air, 20–40% less chiller energy, capacity restored on the hottest days. Proven at data centers and universities across the Kingdom.

15–25°C cooler air entering the condensers — from water evaporation alone

20–40% chiller energy reduction, measured on delivered projects

1.5–2.5 yrs documented payback range in KSA

The problem

Air-cooled plant loses capacity exactly when you need it.

Air-cooled chillers and condensers are sized for hot days — but when entering air passes 45°C, they lose capacity exactly when the building needs it most, and burn maximum electricity doing it.

The solution

PreCooll applies Oxycom's adiabatic principle to the plant itself.

A wetted OxyVap wall around the chillers, served by Aquamizer hydraulic modules, pre-cools the entering air by 15–25°C using only water. Compressor work drops 20–40%, peak demand falls, lost capacity is restored, and trips on extreme-heat days stop.

Data centers, universities and industrial plants in the Kingdom run PreCooll today: DAMAC EDGNEX's Riyadh data center measured a 35% chiller energy reduction and 650 kW peak cut; Prince Sattam bin Abdulaziz University's 4,400 TR plant runs ~20% lighter with no more extreme-heat shutdowns. Documented paybacks run 1.5–2.5 years.

FAQ

Questions engineers ask us.

It suits air-cooled chillers, condensers and dry coolers with accessible air intakes. The survey confirms the arrangement and the expected saving for your specific plant.

Documented projects in KSA show 1.5–2.5 years, driven by 20–40% chiller energy savings and peak demand reduction.

Water is consumed only during hot hours, and smart water management controls bleed and scaling. The energy saved far outweighs the water cost — both are quantified in the study.
