ELFLOW’s Cooling Mist™
Does your air cooled heat exchanger not fit your needs anymore and new installation is deemed too costly?
Please find our Cooling Mist™ system that allows for up to 40% extra heat duty on hot summer days.
Most air cooled heat exchangers are designed to function for a limited average number of days which in effect always limits
plant production during hot summer days as illustrated in the graph below


ELFLOW’s COOLING MIST™ system is a high pressure fogging (chilling, peak cooling) system used to influence ambient climatic conditions specialized in the Energy, Petrochemical and Oil & Gas industry where there is a need to increase cooling/condensing capacity. By evaporating billions of micro fine droplets in the inlet air of an Air Cooled Heat Exchanger, adiabatic cooling is attained and the evaporative effect results in a drop in inlet temperature, resulting in an increase in efficiency. The evaporative cooling system effect on Air Cooled Heat Exchangers will have a direct positive effect on Process production. As we design each COOLING MIST™ system specifically to Your system, we can guarantee at least 95% evaporation of the water which guarantees You that there is no damage to your finned tube bundle or mechanics and minimum usage of water for maximum cooling effect. A strong inverse relationship exists between the Dry Bulb Temperature and Relative Humidity, which is more pronounced during the hot summer days. Whenever the ambient temperatures are high, the coincident relative humidity is always lower. Our COOLING MIST™ systems make use of these typical weather phenomenon and is therefore able to cool down the air by as much as 10.5* in hot dry climates.
Our COOLING MIST™ systems offers clear advantages to the end user such as

  • Immediate measurable positive cooling effect
  • Maximum evaporation capacity (total evaporation of the water used)
  • Adjustable cooling to desired level – multistage system
  • No negative effect on your airflow
  • No structural modification or drilling of the support structure (no drilling or welding required)
  • Low capital expenditure (excellent price/quality ratio) and barely any operational & maintenance costs and rapid payback
  • Adaptable to any existing air cooler or air condenser unit
  • Very fast installation time – No operating system downtime
  • High level of reliability. We only use A quality materials such as SS316
  • Simplicity of system and minimum space requirements
  • No increase in existing noise level of air coolers (just a pump at 80 dBA that can be isolated)
