PDX cooled unit is engineered to safely integrate R-454B refrigerant and continue delivering the benefits of direct gas-fired, 100 percent outdoor air ventilation, cooling, and heating.
Modular design provides the most configuration flexibility and expanded heating and airflow capacities
Range from 800 to 15,000 cfm including ultra-efficient heating capacities up to 1,600,000 BTU/hr
Our proprietary barometric pressure damper system provides for at least 50% turndown in airflow in variable volume applications, an additional 250% turndown over our nearest competitor, which means improved energy savings without added cost
Designed for maximum weather resistance, XDG housings are constructed of heavy-gauge G90 galvanized steel
Large access panels are provided for easy inspection and maintenance of motors, drives, fan wheels, filters and heater controls
Featuring high-quality cast aluminum burners with stainless steel mixing plates
Provides precise and instantaneous temperature control
The control center includes a standard magnetic motor starter, control transformer and disconnect switch. All electrical components are UL Listed, Recognized or Classified and an option for factory prewired single-point power connection
Shafts are precision turned, ground and polished steel sized so that the first critical speed is at least 25% over the maximum operating speed
Fan and motor assembly is mounted on vibration isolators to minimize noise transmission into the building
Air performance ratings from Accurex's accredited test chamber ensure accurate data
All units are tested prior to shipment for proper operation of the gas train, electrical components and airflow
Evaporative cooling, chilled water or direct expansion (DX cooling)
