Horizon® Flex

Application-Specific Outdoor Air Systems

Not every building requires 100% outdoor air or a very low dewpoint, so why invest in more equipment than you need? While our Horizon Flex unit can deliver 100% outdoor air, many customers find that their application requires more than what is delivered in a standard unit but less than a 100% outdoor air, making the Horizon Flex the ideal choice for lower upfront costs.

  • Delivers up to 100% outside air with the flexibility to use less if desired
  • ≥ 51oF dewpoint for occupant comfort
  • Peak load humidity control
  • Lower first cost
  • ASHRAE 340/360 certified to condition air and provide thermal comfort to your space
  • Meets minimum EER and IEER efficiency standards
  • Double-wall insulation for efficiency and quieter operation
  • Hot gas reheat
  • Configurable to suit your needs
    • With or without ERV
    • Air-cooled
