Selecting the proper air conditioner for an indoor industrial enclosure is not necessarily difficult, but requires some basic information about operating conditions, according to ITS Enclosures . For indoor uninsulated metal enclosures, the following formula may be used to estimate cooling needs.
BTU/hr = ( Watts x 3.413) + (1.25 x area in ft sq x DT)
Watts is the total heat load inside the enclosure (sum of all heat-producing equipment).
Area is the total exposed surface area of the enclosure in square feet.
DT is the difference in temperature between the maximum expected degrees F temperature outside the enclosure and maximum desired temperature in degrees F temperature inside the enclosure.
ITS Enclosures offers the Proair Series CR air conditioners with NEMA 12 approval on all models; CE certification; and a unique condensate management system evaporates moisture from the enclosure and eliminates drain tubes, buckets, and wet floors. The series is functionally tested and uses environmentally safe refrigerant. High-capacity blowers are said to maximize airflow.
