Often, in large industrial buildings, there are locations inside the plant where the heat is concentrated for a variety of reasons. It might be a furnace operation, or a part of a painting process, or a concentration of people or a cluster of injection moulding machines. In all these cases, we do not need to air condition the whole building, we only need that particular spot to be more comfortable.  Spot cooling by a Breezair Evaporative Air Cooler can dramatically improve the conditions in that location and the productivity of the plant, costing much less than installing conventional air conditioning.
