Aztec Indirect and Indirect/Direct Evaporative Cooling Systems

Evaporative cooling is the most energy efficient and cost effective form of cooling that exists. Equipment cost is lower than a refrigeration system, installation is simple and inexpensive, and operating costs are a fraction of refrigeration systems. Evaporative cooling units are also environmentally friendly as they cool efficiently without the use of compressors or HFC refrigerants.

The Evaporative Cooling ventilation system provides fresh air to the building; forcing the hot, stale air out. These units provide maximum comfort when you need it the most. The hotter and drier the air, the greater the cooling effect.

The Indirect system uses evaporative media in a cooling tower to cool water down to temperatures approaching the wet bulb temperature. This water is then pumped through a water coil to lower the entering air temperature without adding any moisture to the airstream. An Indirect/Direct system will also have a direct evaporative module downstream of the indirect section. This section will lower the dry bulb temperature even more by adding moisture to the airstream.

The Aztec ASC series offers air deliveries from 1,500 CFM to 37,500 CFM. Optional indirect fired heating sections can be added with up to 1,400 MBH Input.
