Adiabatic Coolers

Product Highlights

Adiabatic Coolers

Adiabatic Coolers offer minimum footprint, low energy use and water supply temperatures similar to evaporative cooling towers. For the majority of the year the cooler operates as a dry air blast cooler reducing water costs to a minimum.

Premium Adiabatic Coolers

Unlike standard adiabatic coolers, our premium adiabatic coolers operate without external aerosols keeping the coil blocks dry, eliminate scaling and avoid the risk of the proliferation of bacteria such as legionella.

  • No chemical water treatment
  • No clean and chlorination
  • Sealed system
  • No water losses through evaporation
  • Low operating noise levels
  • Minimal plan area
  • Low operating costs

What is Adiabatic Cooling?

Adiabatic cooling is achieved by reducing the air inlet temperature being drawn over the coolers coil block. This reduced oncoming air temperature, achieved by creating a fine mist at the coolers air inlet, allows the cooler to supply water temperatures as low as 25°C in the Summer period.

Adiabatic Coolers vs Cooling Towers

Adiabatic Coolers reduce running costs, water use, chemical water treatment and stringent maintenance regimes associated with evaporative cooling towers.

Adiabatic Cooling Benefits;

  • No chemical water treatment
  • No registration with local authorities
  • Lower operating costs than cooling towers
  • Lower water use than cooling towers
  • Minimal maintenance
  • Operation in the UK as a dry air blast cooler for over 95% of the year
  • No unsightly plumes of water vapour
  • No contamination of the water circuit
  • Multiple fans unlike a typical tower with one fan
  • Extended Warranties

Cooling Tower Disadvantages;

  • Owners of evaporative cooling towers must register the unit with their local authority under the ‘Notification of Cooling Towers and Evaporative Condensers Regulations 1992 act’.
  • A costly chemical water treatment regime is required for all cooling towers including chlorinations and cleaning.
  • Responsibility and weekly record keeping of water quality for cooling towers is borne by the owner and must be kept up to date.
  • HSC guidance on the control of legionella in water systems states that the option of dry cooling should be considered particularly when cooling towers are due to be replaced or when new cooling systems are planned.
  • Cooling Towers by their very design evaporate water to remove heat and need constant water make-up to operate, a constant water bleed is also required to avoid the build up of total dissolved solids in the system which creates cooling issues. This high water use increases running costs further.
