Selecting the right Essick cooler is EASY
1.Consult zone map to find correct size.
2.Consult table below to find correct “minutes per air change” for your zone.
3.Determine area to be cooled in cubic feet (building height x length x width.)
4.Divide cubic feet from step three by minutes per air change (step 2) to determine CFM.
5.Select correct Essick Cooler model in the specifications table according to CFM and expected static pressure.
Minutes Per Air Change

HEAT LOAD | HEAT LOAD | 1 | 2 | 3 | 4 |
HIGH | EXPOSED | 2 | 1.5 | 1.3 | .7 |
HIGH | INSULATED | 3 | 2 | 1.5 | 1 |

IF CFM falls between models, choose the larger model. Interior Heat Load: High means places with unusual heat sources from hot equipment or processes, crowded conditions, etc. Normal means no unusual heat sources - typical home or office. Exterior Heat Load: Exposed means walls and/or roof exposed to sun, poor insulation, etc.
Insulated means walls and roof well insulated and/or shaded.
For Example:
A house in Phoenix AZ. is 40 ‘ long by 30 ’ wide with 8‘ ceilings and has standard insulation with no unusual heat sources.
1. | Establish cubic feet: 30 x 40 x 8 = 9,600 cu. ft. | 2. | Determine Zone: Phoenix is in Zone 2 |
3. | Use chart to discover Minutes Per Air Change: 3 | 4. | Compute Cubic Feet per Minute (CFM): 9,6003 = 3,200 CFM |
5.Review Specification Charts inside brochure to determine which unit meets the needs.
In this example, the N43/48D with ½ h. p. motor is indicated (assuming a typical static pressure of 0.2). Essick Air Products 5800 Murray Street , Little Rock, AR. 72209 800
