48/50HG HIGH-EFFICIENCY SERIES The Centurion Rooftop GAS/ELECTRIC, 12.5 25 TONS ELECTRIC/ELECTRIC, 12.5 25 TONS INDUSTRY-LEADING EFFICIENCY PLUS ADVANCED COMFORTLINK CONTROLS
Advanced IAQ features that will keep everyone comfortable. From the overall control systems right down to the sloped drain pan that prevents microbial growth by eliminating standing water, the Centurion is designed to meet IAQ objectives without sacrificing operating efficiency: In addition to continuously monitoring system performance, our leading-edge ComfortLink controls are a key part of the Centurion unit s ability to efficiently maintain optimum IAQ. ComfortLink optimizes the Centurion s performance by continuously adjusting the compressors, unloaders, expansion valves and condenser fans as conditions change. Our patented MoistureMiser package, available as an option, improves the system s moisture removal capability as much as 40%. That keeps humidity levels down without having to use an oversize unit or overcooling the space, maximizing both energy savings and comfort levels. Carrier s patented UV-C lamp technology uses ultraviolet radiation to kill mold and bacteria before they get into your building. A gear-driven economizer with Belimo actuator and CO 2 sensor ensure efficient and adequate outdoor air ventilation, greatly enhancing Carrier s demand control ventilation strategy when used with variable air volume (VAV) applications. Standard two-inch and four-inch 30% pleated filters stop contaminants before they get into the conditioned space. Centurion Benefits at a Glance Best efficiencies in the industry up to 11.5 EER. ComfortLink controls display information in clear language, simplifying rooftop configuration and efficiency control. Fits existing standard Carrier DP/DR and TJ/HJ roof curbs, eliminating $1200 $1500 per unit transition curb cost. Field convertible to side supply no curb adapter needed. Dual or triple refrigerant circuits are fully independent for enhanced reliability and efficient part-load operation. Extremely reliable and redundant scroll compressors with internal and external vibration isolation. E-Coating epoxy post-coating process resists corrosion better than dipped and baked coil coatings for tough industrial and coastal applications. Thermal expansion valves (TXVs) closely match cooling capacity to building load requirements without costly and inefficient hot gas bypass modifications. Hinged access panels, slide-out fan deck, easy-access/easy-clean coils and other features cut service time.
Innovative design, energy efficiency and air quality features to protect your bottom line. The Carrier Centurion is redefining the market for rooftop units in the 12.5-to 25-ton range. Never before have the highest operating efficiencies in the industry been combined with advanced ComfortLink controls that simplify operation and bring even more efficiencies. Maintenance will also be extremely efficient, thanks to the well-thought-out design. For these reasons and many others, Centurion rooftops are the smart choice for building owners and consulting engineers. Peak efficiency for lower lifetime cost. Buy an economy rooftop unit and you ll get one-time savings. But buy an energy-efficient Centurion rooftop unit and you ll enjoy savings every month. The Centurion s EERs aren t just good, they re the best in the industry up to 11.5. That means a typical Centurion user will save up to 25% of the purchase price every year, compared to an equivalent unit with the ASHRAE minimum EER. Besides making the most of every kilowatt-hour, Centurion rooftop units keep operating costs down by precisely adjusting their operation to match the building load. Fully independent dual or triple refrigerant circuits with thermal expansion valves (TXVs) permit efficient part-load operation down to 33%, while enhancing reliability and eliminating the need for costly and inefficient hot gas bypass modifications. Our controls speak your language. Would you rather decipher blinking LEDs and codes, or use controls that communicate in plain English, Portuguese, Spanish or French? The ComfortLink control system makes it as easy as possible to monitor and control each Centurion rooftop unit and the building s IAQ. A large scrolling marquee acts as a window into the unit s operation, providing easy-toread information about IAQ and over 15 diagnostic read/write functions. This intuitive interface greatly reduces startup and operator training time. ComfortLink is your HVAC automation system. It lets you monitor and control multiple Centurion units peer-to-peer by simply daisy chaining them together, connecting them to a LAN, and using your laptop computer with Carrier s ComfortVIEW software at a fast 38.4 k. There is no need for an expensive black box or any other additional hardware. Easy to install and maintain. Our Centurion rooftop units can save you money even before they re installed. They use the same Carrier DP/DR and TJ/HJ roof curbs that many units have used for over 20 years, so if you re replacing a unit you ll avoid the high cost of a transition curb. The Centurion is field convertible into a side-supply unit with horizontal side-by-side supply/return ducts. No horizontal transition curb is required, which eliminates another significant expense, along with the pressure drops horizontal curbs can cause.
The Centurion also saves you money after installation. All service access panels are hinged for the convenience of service personnel. The fan section slides out, making it easy to replace and align belts, and access all indoor blower bearings. The coils are easy to access and clean, and all filters can be easily replaced important for maintaining IAQ. The scroll compressors and piping are also extremely accessible. These features add up to faster, less expensive maintenance. Multiple compressors for reliability and efficient part-load operation. Engineered for trouble-free performance. ComfortLink controls display IAQ and system status in clear language. Every component of our Centurion rooftop unit is designed for reliability. The dual or triple refrigerant circuits are completely independent, so even if one circuit fails, the other(s) will continue to provide partial cooling. Each refrigerant circuit has its own extremely reliable scroll compressor with internal and external vibration isolation. Centurion controls are programmed to provide compressor redundancy if one compressor fails to respond at startup, built-in controls automatically start the second compressor. The TXVs that manage the flow in each refrigerant circuit are extremely reliable as well. To protect coils used in corrosive urban, industrial or coastal/marine locations, we offer a number of options. The ultimate is our E-Coating, where a precisely controlled scientific process bonds an impermeable epoxy coating to the specially prepared fin coil surface. Lasting three to five times longer than other popular post-coatings, E-Coating provides maximum protection in virtually all environments. Should a problem develop, technicians will be able to diagnose it quickly, since the ComfortLink controller continually monitors all key systems.
Gear-driven economizer ensures efficient and adequate outdoor air ventilation. E-Coating resists corrosion in harsh environments. The fan section slides out for faster, easier maintenance.
