Customer Questions & Answers

I have a 2800 square ft open building. It has three sets of French doors with three windows. Is it best to keep them all

Closed withe the port a cool operating
Asked by: AD
It is best to keep some doors and windows open. Portacool units need air flow and circulation to cool effectively. If there is not enough air circulation, it will recycle the same air each time and can add humidity. With doors open, it can pull fresh air and cool better.

I have a 20 x 20 sq ft greenhouse. It has a 10ft height. Can this unit cool it even with the height?

Asked by: Superques
The unit cools a space of up to 4000 square foot. It is more like a spot cooler, so the area that the fan is blowing on will experience the temperature drop. For a space that size, you would usually need a smaller unit such as the Cyclone 3000, PAC2KCYC01, that cools up to 700 square feet.

How much water does this unit use per 8 hour day

Asked by: Bobv
The unit has a 40 gallon tank but uses approximately 30 gallons of water per hour. Therefore this unit uses 240 gallons of water in a 8 hour period.

Rated 5 out of 5 by from Worked well for us. Bought 2 of these for our County Fair to cool animal exhibits in an uninsulated metal building. They worked very well for that purpose. They appear to be very well made and we expect to get many years of use out of them.
