Commercial Strategos (SG/SC) Rooftop Units

The Most Energy-Efficient Rooftop Unit in the Industry.

Features and Benefits

  • Efficient operation
  • Up to 16.1 SEER, up to 14.3 EER and up to 16.4 IPLV.
  • Available in 3, 5, 10, 20 and 24 tons
  • ENERGY STAR® qualified.
  • Integrated Modular Controller – provides centralized control and fast, simple troubleshooting to reduce service cost and improve performance.
  • Multiple Compressors – allow the unit to provide efficient cooling with up to four stages of cooling capability.
  • Independent Motor Mount – allows for easy, efficient access without removing top panel.
  • Full-Perimeter Base Rail – provides greater structural integrity, so the unit is easier to handle when rigging and transporting.
  • Slab Coil – permits faster, more thorough cleaning of condenser coil.
