Natural pre-cooling cuts costs by over a third

A relatively small investment that saves more than a third on your operational cooling costs is a rare opportunity. PreCooll reduces your environmental footprint and, by realizing significant energy savings, also your AC running costs. The PreCooll proposition becomes even more attractive and profitable when the real long-term costs of industrial cooling systems are fully taken into account.

In spite of their obvious shortcomings, compressor-based AC systems will remain in use for many years to come. Natural pre-cooling, of the kind delivered by PreCooll, is by far the simplest and most effective way to achieve significant savings. By reducing peak demands with up to 60 percent, pre-cooling also provides welcome relief for overloaded power grids.

Upgrade existing systems and lower energy use by 30 percent

Compressor-based cooling and refrigeration systems are responsible for 50 percent of the world’s total electricity consumption. Especially during the warmest days, they waste enormous amounts of energy. Many countries struggle with the power demand surges caused by these widely-used cooling systems. Now there is PreCooll to upgrade your existing system and cut down energy bills by 30 percent.

PreCooll creates a cool microclimate around your industrial cooling system with the help of Oxyvap®, the highly efficient direct evaporative cooling pads developed and produced by Oxycom. In warm climates, Oxyvap® can lower the inlet air temperature by as much as 25 °C (45 °F). Self-cleaning, made of inorganic materials and with the lowest possible air resistance, Oxyvap® guarantees safe operations and maximum savings for many years.

Adiabatic cooling of the ambient air before it enters the system is the fastest way to lower energy consumption. The steady supply of cold air to your condenser not only boosts efficiency, it also contributes to longer equipment lifetime and lower maintenance costs.


Key to PreCooll’s performance is the intelligent AquaMizer pumping station. Maximum water efficiency is achieved with state-of-the-art sensors and control algorithms that monitor the ambient conditions and determine the operation modes, ensuring the PreCooll system is active only when necessary. The fully automated water management system continuously monitors water quality, drains the system and refreshes the water when mineral levels reach certain values.
