Captiveaire's Superior Dedicated Outdoor Air System
Backed by 40 years of ventilation expertise, Paragon by CaptiveAire is the ideal HVAC solution offering exceptional energy savings and unprecedented comfort and humidity control.
Paragon: Dedicated Outdoor Air System
Paragon is designed from its core to conserve energy and save on operating costs. Paragon’s rare earth magnet inverter scroll compressor eliminates excessive cycling, premature unit aging, inefficient hard starts, and unnecessary energy consumption. Paragon’s modulating technologies allow it to deliver the highest efficiencies at part-load conditions.
Paragon contains fully modulating refrigeration and optional hot gas reheat components that deliver the exact amount of air requested at the desired temperature and humidity. Variable speed components allow Paragon to adjust its heating and cooling capacity to match the required load. This provides a consistent temperature throughout the space and avoids large temperature swings often associated with single stage equipment.
Paragon achieves an impressive 20.2 IEER rating (Integrated Energy Efficiency Ratio) which is over 1.5x the ASHRAE 90.1-2016 IEER standard. Designed with the future in mind, Paragon is poised to exceed rising IEER standards for years to come.
Paragon comes standard with a 5 year parts warranty. An extended 10 year full unit warranty is included at no extra charge when units are maintained with a CASService Preventative Maintenance subscription (terms and conditions apply). Paragon is designed with sustainability in mind and is built to last up to 25 years.

Paragon's Modulating Capacity - Precise IAQ
A CaptiveAire Paragon unit was commissioned this past February for a commercial laboratory in Maryland. The existing space
conditions prior to the installation were poor, with overpowering Formaldehyde smell. The Paragon unit quickly
and significantly improved the indoor air quality by bringing in 100% fresh outside air with precise conditioning.
Over 3 months of continuous operation since commissioning:
- Maintained space temperature within the 68°F and 73°F set points 97% of the time
- Space temperatures never exceeded +/- 2°F of the range
- Cooling with reheat functionality maintained the space relative humidity below the desired 58% RH set point 97% of the time
The unit’s operation has spanned February through early May. Traditional On/Off units have difficulty meeting the lower demands of this transition season due to excessive cycling. The Paragon’s modulating heating and cooling capabilities turn down to meet this “shoulder season” demand.
- Combined heating and cooling runtimes of 38 and 13 days, respectively
- Average compressor speed at 38% of full speed
- Average compressor runtime of 70 minutes – cycling reduction protects the unit and extends its useful life
Conclusion:
CaptiveAire’s Paragon unit met the laboratory’s tight space conditioning demands while also delivering fresh outside air. The employees commented on the drastic difference in indoor air quality and the manager was very happy with the improvement.

A Tale of Two Franchisees – DOAS vs. RTU
CaptiveAire serves and monitors a restaurant chain with two franchisee locations in Kansas City. One of the locations, Site A, utilizes CaptiveAire Paragon units (DOAS) to handle the HVAC demands and the other location, Site B, utilizes traditional On/Off rooftop units (RTUs). The restaurants have nearly identical building design parameters and operation patterns. CaptiveAire analyzed the space condition and equipment usage data at each site to compare the off-peak performance during the transition (“shoulder”) season.
Data trends from March through May suggest Paragon as the superior solution:
- More precise space temperatures show improved comfort
- Lower overall utility costs
- Despite fully conditioning the kitchen's make-up air
- Proper runtime from superior controls and setback implementation
- 32% reduction by eliminating excess overnight HVAC usage
- Less equipment cycling from full modulation extends unit lifetime
- 56% fewer cooling equipment cycles
- 76% fewer heating equipment cycles
- Reduced need to mix return air to condition outside air
- Met the same conditioning demands with 57% less total air movement and significantly cut blower energy demands
- Less total air allows for downsized, reduced-cost ductwork
Conclusion:
As demonstrated by the data gathered, traditional RTUs can experience difficulties handling off-peak times of the year. This may result in excessive unit cycling, reduced equipment lifetime, and uncomfortable variations in space conditions. Given that most locations spend the majority of the time in these offpeak weather conditions, the modulating capabilities of the Paragon unit offer a vastly superior solution.
