Hybrid Dry/Wet Coolers

We specialise in sales of hybrid dry/wet coolers throughout Brisbane, Queensland and Australia. We can supply you with just about any size hybrid cooler that you need. 

We use and recommend Frigel Australia. Frigel provide advanced process cooling technology designed to optimise results in efficiency, water and chemical use and uptime. Further information can be found here.

What is a Hybrid Dry/Wet Cooler?

The hybrid cooler is a combination of an air cooled heat exchanger and a wet cooling tower. It transfers heat from a process to the atmosphere by means of either dry cooling or evaporative heat transfer. The operating mode depends on the heat load, the air flow rate and the ambient air conditions. The process cooling water is a finned tube heat exchanger. The bundles are arranged in a V-shape configuration

Why should we use them?

We use and recommend Fibreflow Cooling Towers. Fibreflow technology offers significant benefits over traditional water-cooled systems, such as: -

  • Eliminating the risk of Legionella
  • Lower water consumption (reduced by 75%)
  • No water treatment chemicals required
  • Compliancy is no longer an issue (RMPs & regular audits)

Wet water cooling towers in high energy physics facilities are state of the art. The advantages are robustness, effectiveness and cost-effectiveness. The return water temperature is lower than the air temperature due to cooling via evaporation. The disadvantages are the high water consumption, which becomes more costly in the future and the soiling of the heat exchangers. If the water source is taken from wells then the drawdown of the ground water level has to be taken into account. A hybrid dry cooler is a combination of a dry air cooler during cold and moderate seasons and additional wet cooling during the hot summer season. The cooling surface is moistening by adding water to increase the cooling capability by a factor of 250%. By this the hybrid dry cooler saves a lot of water. The water consumption can be reduced by 80% compared to a wet cooling system. This contribution presents the consumption and the requirement of the make-up water and an estimate of the behavior of the temperature control.
