Van Spall Associates introduced the Adiabatic dry coolers to the UK air conditioning market over forty years ago. Since then, our adiabatic dry coolers have been installed on many additional applications where low re-cooled water temperatures are required.

  • Diesel/gas engine intercoolers
  • Hydraulic oil cooling
  • Absorption chillers
  • Engine dynamometers
  • Robot wielding machines
  • Heat pumps
  • Geothermal
  • Foundry cooling
  • Sludge cooling
  • Data centres
  • Steam turbine condensers

Our Adiabatic dry coolers comply with all current HSE guidelines, are environmentally friendly, safe to use and maximise power and water savings. Standard features incorporated are,

  • Spray water is introduced to the incoming air stream and is not directed over the heat exchanger coil
  • Minimal water usage
  • This is a once through system, no water is re-circulated and therefore no water treatment is required.
  • All spray water is passed through an ultra violet light disinfection system
  • On cessation of the spray cycle all water remaining in the spray pipe work system is automatically drained.
  • An automatic purge timer is installed on the incoming water supply.
  • Should the ultra violet lamp fails, the spray system is shut down until the lamp is replaced.
  • There is no water carryover through the fans.
