EVAP Indirect/Direct Evaporative Cooling System

The Sierra Aztec evaporative cooling system is the ultimate in energy efficiency, providing impressive reductions in supply air temperatures rivaling mechanical refrigeration. The Aztec uses a first stage integrated stainless steel cooling tower and cooling coil to provide cooled air to a second stage direct evaporative section, delivering performance of up to 30 EER. Available in sizes from 1500 to 37000 cfm, the Aztec is also available with a heating section up to 1.4 mbtu input.

Aztec Evaporative Cooling

Features

  • Multi-stage rooftop evaporative cooling system for make-up and ventilation
  • As much as 30° drop at 100°/74° F design conditions
  • Provides up to 119% saturation efficiency
  • Performance far exceeding typical evaporative systems
