This graph shows how the new Snap Cap Double Play system is much better than an evaporative cooler. Not only does the Double Play system maintain a significantly cooler temperature range than the office cooled with a swamp cooler, it also has a much lower relative humidity and so feels more comfortable. The spike on the afternoon of July 31^st was due to maintenance on the swamp cooler, during which time the unit was turned off. Another benefit of the Double Play system is that it doesn’t produce a draft and thus the temperature is more consistent over the whole room.
