Roof Top Units

Features and Benefits

---

Efficient Operation

• Standard and high efficiencies available in 21- to 30-tons, up to 12.3 SEER and up to 11.7 EER
• ASHRAE 90.1 compliant
  ENERGY STAR® Qualified

Improve Efficiency, Reduce Service Costs and Prevent Downtime

• Integrated Modular Controller – provides centralized control and fast, simple troubleshooting to reduce operation and service cost
• BACnet® Module – allows two-way communication for system monitoring, diagnostics and remote troubleshooting
• Humiditrol® Dehumidification System – helps control humidity levels, improving comfort and indoor air quality
• Multiple Compressors – allow the unit to provide efficient cooling with four-cooling-stage capability
• Thermostatic Expansion Valves – provide peak cooling performance across the entire application range for better comfort
• Variable-Frequency Drives (available on select tonnages) – provides variable air volume unit operation to meet a variety of zoning system needs

Application Solutions for Efficient Operation

• 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 coil cleaning
• Hinged Toolless Access Panels – provide quick access to components and protect panels and roof from damage during service
• Isolated Compressor Compartment – allows performance check during normal compressor operation without disrupting airflow
• Slide-Out Blower Deck – improves access for belt, blower and motor, reducing maintenance time

Reliable Performance

• Corrosion-Resistant Cabinet – galvanized steel cabinet under a two-layer painted surface protects against rust and corrosion
• High- and Low-Pressure Switches – safeguard compressor from extreme operating conditions and unnecessary wear and tear
