Has anyone looked at the Deltec Eco Cooler?
Basically, it's an evaporative cooler, same principle as those IWATAs that you see in malls, groceries, etc.
I have one (one of those big Iwatas) in my factory, and it does help cooling.
I'm thinking of getting one of those cheap coolers you see in Ace Hardware and all (the important thing is not to get the models with the paper-type cooling element -- the plastic netting element is not as efficient, but it's closer to the DLS materials that the Deltec uses).
One of these days, subukan ko nga iyon.
