Focus on energy efficiency and water conservation

Hybrid coolers are optimised for water-saving: during colder annual hours, or at partload operation, the cooler is controlled by the Jaeggi HybriMatic ® control to operate dry, ie with convective heat transfer to the ambient air.

Only when the required return water temperature cannot be achieved by dry-cooling is the wetted mode automatically activated. Although the cooler then works through natural, energy-efficient evaporation, it saves 70-90% of annual water consumption as compared to wet cooling towers, and proportionately reduces the associated operating costs.

In multiple cooler installations, the wetting mode is actuated progressively across the coolers as the ambient temperature rises, so that the period of fully evaporative operation is limited to only a few operating hours each year.

Energy consumption is minimised through the use of axial fans with inverter speed
control and electrical motors with class Eff1 energy efficiency.

Jaeggi has continued to develop the patented hybrid dry cooler since 1991 with around 1800 installations in Europe.

The innovative Swiss-engineered high-tech product is successfully used in many diverse applications; such as heat rejection for air conditioning/climate control or in industry to produce cooling water.

Hybrid coolers are available in various sizes for cooling capacities of 100 - 3,500 kW per unit, and are increasingly used to replace installations with wet cooling towers or dry coolers. Contact Martin.Scott@jaeggi-hybrid.ch
