What is closed-loop dry cooling system?


The strength of a closed-loop dry cooling system is that the unit is very simple and relatively easy to install. The energy requirements are relatively low and it is easily controlled. Maintenance is normally low requiring only periodic inspection, lubrication, and testing of the fluid.


The weakness of a closed-loop dry cooling system is that it is dependent on the atmospheric dry bulb. For example, if your location’s design dry bulb is 100 F in the summer and your equipment requires 90 F coolant; at best the system can only supply around 105 to 110 F coolant to the load. In this case you would need supplemental cooling to get the coolant temperatures down to 90 F.


The closed-loop dry cooling system also requires free clear air to work efficiently. This means that the fluid cooler must be placed in a location that is not affected by the prevailing winds, not too close to a building that will allow the warm exhaust air from the fluid cooler to be recirculated back to the fluid cooler, and finally not in a location that has heavy concentrations of dust, dirt, leaves, seeds, etc.


Many times the best location for the fluid cooler is on the roof. Since the fluid cooler is located outside the coolant must also have a concentration of some type of glycol to prevent freezing if your location has a design dry bulb in the winter that dips below freezing. If the location is very cold, the concentration of glycol may need to be significant to prevent freezing. Glycol concentrations as they increase begin to reduce the rate of heat transfer. For example, if you need 50% ethylene glycol concentration with water the heat exchanger equipment and the flow/pressure of the coolant will need to increase to adjust for the glycol concentration. Larger fluid coolers and pumps will increase the cost of the system over those with lesser concentrations of Glycol/water. This cannot be prevented in colder climates.



  • Our range of Dry Air Coolers and Radiators are designed for commercial and industrial fluid cooling applications.
  • We offer a wide range of options to provide the most cost-effective solution for your cooling requirement.
  • Standard arrangements include flat-bed vertical or horizontal airflow with V configurations to offer the smallest footprint.
  • Whether your application is cooling water / glycol for water cooled chillers, injection moulding machines, furnace equipment, CHP Engine Cooling or any other process. One or more of our units can be selected to provide the most cost-effective solution to suit your space and noise requirement.
  • Energy saving free cooling is possible for much of the year for many applications.
Material options Heavy-gauge hot-dip galvanized steel is used for unit steel panels and structural elements featuring a zinc aluminium coating.
Heat transfer media: A. The dry cooler is constructed of staggered and seamless copper tubes (15,9 or 12,7 diameter) with aluminium, rippled and corrugated fins (0,14 or 0,17 thickness).
  B. 2.5 mm fin spacing for optimal air turbulence
  C. Thick and seamless copper headers and threaded steel connections
  D. Pressure tested at 30 bar
  E. Try our options for aggressive environments: special pre-coated anti-corrosion aluminium fins or copper fins (0,2 mm thickness).
Air movement system: A. Axial fan with exceptionally compact direct drive short integrated motor and fan guard.
  B. The fan features an impeller and motor and is balanced as a complete unit using dynamic single plane balancing. Balance grade is G6.3.
  C. Fan and motor totally maintenance free.
  D. Bearings seals and motor encapsulation for long service life.
