What is indirect evaporative air conditioning? 

Our indirect evaporative air conditioners use a hyper-efficient counter-flow heat exchanger to produce 100% fresh, cool, outside air, with no added moisture. The fresh cold air produced can be similar to that produced by refrigerated systems, with temperatures that approach the ambient dew-point temperature.

It is ideal for use as a DOAS (dedicated outdoor air system), data centre cooling or for comfort cooling applications.  Climate Wizard covers an exceptionally large range of flexible configurations in a wide range of industries.

Consider Climate Wizard Commercial Solutions

Climate Wizard provides hyper-efficient cooling of outside air and up to 80% lower energy costs* compared to equivalent refrigerated air conditioning systems, with the added benefit of supplying 100% fresh, cool air into the building, increasing Indoor Air Quality (IAQ).


Climate Wizard is a simple, reliable solution to improve COP/EER (coefficient of performance/energy efficiency ratio).  Tested in our NATA (National Association of Testing Authorities) accredited laboratory# it offers:

  • Flexible design and engineering configurations
  • Features an Auto-CleanseTM water management system to minimise water consumption and to maintain quality
  • Easy access to spare parts and supported by a national service network

# Testing of the CW-80 units in the NATA accredited Meridian Test Laboratory is not possible due to their large and unique size.
