Dedicated Outside Air Systems

PEFY-AF

Overview

The PEFY-AF Dedicated Outside Air System comes in two configurations, the CFM (without reheat) and the CFMR (with reheat). Both configurations offer a high capacity coil that conditions incoming outside air, making it suitable to be distributed to down–stream fan coil units.

  • Single-speed 1200 CFM fan
  • Multiple external static pressure set points
  • Large DX coil with high latent capacity
  • Entering air temperature and humidity sensors factory installed
  • Thin 18-9/16" high cabinet installs in small areas
  • Drain lift mechanism up to 21-11/16" included as standard
  • 50° F to 70° F saturated air available in cooling mode (CFM/PUHY-P120)
  • Reheat capabilities using recovered energy from cooling through the branch controller (CFMR/PURY-P120)
  • 50° F to 60° F saturated air available leaving cooling coil (CFMR/PURY-P120)
  • 63° F to 83° F leaving air temperature available leaving reheat coil (CFMR/PURY-P120)
