That depends on the temperature and humidity of the outside air (the ambient temperature). Have a look at the temperature chart below and you will see the answer. For example, at a temperature of 25 C and a relative humidity of 50% the air from a Breezair Evaporative Air Conditioner will be at 20 C, i.e. a 5 C drop. Or, at a temperature of 35 C and a relative humidity of 30% the air from the Cooler will be 25 C, i.e. a 10 C drop.

Yes, because they are simple machines. Those with V-belt drives need the drive system checked and adjusted once a year. Otherwise you need to check and clean the cooling pads regularly, depending on the level of pollution in the environment – at least every 6 months. In clean locations, once a year is enough. Clean cooling pads mean highest cooling performance and that is what you want. Check the water tank (reservoir) once a year and clean out if necessary. Follow the Owner’s Guide book.

The amount of water used is directly proportional to the amount of cooling being supplied — more water used, more cooling supplied. The water consumption is also affected by the humidity of the day — more humidity, less water used. It also depends on the setting of the machine — high speed operation uses more water. And finally, it depends on the Bleed setting. As a guide we can advise that, at minimum Bleed setting and at high speed setting and at a Relative Humidity (RH) of 30%, the water usage is about 7 Litres/hr per 1000 m3 /h (600cfm) of air flow. At a Relative Humidity (RH) of 50% the rate is about 5 Litres/hr per 1000 m3 /h air flow. For example, a TBA550 has an air flow of 10800 m3 /h at 80 Pa so it will use about 76 Litres/hr at 30% RH and about 54 Litres/hr at 50% RH.

Yes it does. The hot dusty air from outside is cleaned as it passes through the wetted cooling pads, where airborne particles are trapped by the cooling pads and many smaller impurities such as pollens and pollution are also reduced.

Often, in large industrial buildings there are locations within the building where the heat is concentrated for a variety of reasons. You don’t need to air condition the whole building, you only need that spot to be more comfortable. 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. Spot Cooling by Breezair can dramatically improve the conditions in that location and improve your productivity and cost you much less than installing conventional air conditioning.
