I know this is out of the blue, but can you please make a discussuon or what are your thoughts about this AirDisc Aircon?

Not familiar with the product. Would need to see the specifications and capacities charts.Often time these invention lack the ability to pull moisture from the air, leaving the air slightly cooler but still humid. Send the specifications if you would like us to research it for you, and we'll have a look when time allows.

Sounds like an engineer should review your situation. Did the A & B Areas have different classifications and Air Change Requirements? @@ap14spt
