NG Series Dry Coolers

Scroll to Bottom

Our dream was to design and build our own
proprietary outdoor condensers and dry coolers
to deliver the ultimate in quality, reliability and
performance to our customers.



  • outdoor heat rejection technology engineered for maximum efficiency and reliability
  • dry coolers with the most advanced, ultra-quiet and energy-efficient fan designs
  • coated outdoor heat exchanger coils that use innovative technology to deliver the ultimate in corrosion resistance and maximum efficiency at lower pressure drops
  • modular V-bank dry coolers that provide a minimum fluid pressure drop even with large volumes of fluid
  • the ideal heat rejection technology for indoor pool dehumidification and other applications
  • direct-drive fans (EC motor or two-speed) provide improved efficiency, scalable performance and quieter operation

Here’s how we did it.


NG Series

Efficient, consistent and controlled heat rejection is the heart of every cooling technology. That’s why as the world leader in natatorium dehumidification equipment, we decided to build our own dry coolers.

By designing and building to Seresco’s own exacting standards, we’ve been able to increase heat rejection performance while reducing both the size of each dry cooler and the energy it consumes to get the job done – while actually increasing performance!

Seresco outdoor dry coolers are more environmentally friendly by using a water/glycol mixture as a heat exchange fluid. The NG Series of dry coolers deliver premium performance, exceptional energy efficiency and extraordinary life expectancy in a compact economical footprint.
