 Unique Features:

  • CW Manifold Piping Welded & Installed By Titan
  • Two Speed Blower Operation via VFD
  • Piezo Ring Monitoring on Supply Fan Blowers

Application / Equipment Overview:

This extremely large unit was accomplished through a design that was shipped in 5 separate sections.
Steam and chilled water coils are utilized to achieve temperature and humidity controls as the chilled water coil allows for air dehumidification. The unit also employs integrated direct evaporative cooling.
As seen in the technical specifications, this unit also features several unique customer specifications. Additionally, piezo ring monitoring was employed to modulate the supply fans in maintaining design airflow as filters become loaded.
In air recirculation mode, outside air opening/monitoring is utilized to prove minimum design outside air parameters.
