Saving Energy with Intelligence

Efficiency

• Highest efficiency units in its class; with up to 18.0 SEER, 21.5 IEER and 13.9 EER
• Optional SmartAirflow™ system can save up to 35% of annual ventilation energy consumption compared to traditional rooftop units
• Available MSAV® supply fan provides year-round savings and comfort with reduced energy consumption, improved indoor air quality and code compliance
• Effective efficiency levels of 34 SEER and beyond when the SunSource® Commercial Energy System is added
• Available in 3-50 tons (gas/electric and electric/electric)
• Exceeds ASHRAE 90.1-2010 minimum standards by more than 35%
• ENERGY STAR® qualified

Comfort/IAQ

• Corrosion-resistant, removable, reversible, double-sloped drain pan provides application flexibility, durability and improved serviceability
• Patented Humiditrol® dehumidification system allows for independent control of temperature and humidity, providing enhanced comfort control
• Enhanced Humiditrol® dehumidification system (available for 3- to 6-ton units) is up to 20% more efficient
• Foil-faced insulation on all internal surfaces that contact airflow helps minimize airborne fibers and improve IAQ
• Multiple cooling stages helps reduce temperature swings and maintains tighter control for improved comfort

Serviceability

• Hinged access panels provide quick access to components and protect panels and roof from damage during servicing
• Isolated compressor compartment allows performance check during normal compressor operation without disrupting airflow
• BACnet® module allows two-way communication for system monitoring, diagnostics and remote troubleshooting
• 2010 ACHR News Dealer Design Awards "Silver" Winner and 2012 ACHR News Dealer Design Awards "Silver" Winner in the Light Commercial HVAC category

Reliability

• Environ™ coil system significantly reduces refrigerant charge requirements and offers innovative technology that helps maximize reliability and sustainability
• Prodigy® Control System makes setup, troubleshooting and servicing easier than ever. Each unit tracks the runtime of every major component and records the date and time when service or maintenance is performed. The unit controller intelligently operates the rooftop unit to help ensure reliability, maximum efficiency and comfort.
• SmartWire™ system simplifies field sensor or thermostat installation through advanced connectors that are keyed and color-coded to help prevent miswiring
• Scroll compressor provides reliable, long-term operation
• BACnet® module allows two-way communication for system monitoring, diagnostics and remote troubleshooting
• Thermostatic expansion valves, available on high-efficiency models, provide peak cooling performance across the entire application range (fixed orifices are available on standard-efficiency 12.5-ton model)
• Interlink compressor delivers increased reliability and better efficiency
