An Industrial grade centrifugal chiller for your critical commercial needs.

Carrier chillers have always been known for their reliability. In fact, many of our industrial chillers have been operating nonstop, except for normal maintenance, for more than 50 years.

17EX Open Drive Centrifugal Chiller brings that same reliability to the commercial market. Every aspect of this large-capacity chiller has been designed to assure dependable, efficient operation.

A Chiller For The Long Haul

Whether you're installing a chiller in a new project or replacing and existing unit, you can count on the 17EX Open Drive Centrifugal Chiller to meet your most demanding needs. From the design of its compressor to its heavy-duty construction, every aspect of the 17EX is geared for decades of exceptional performance.

And because the 17EX is specifically designed to use HFC-134a, a non-ozone depleting refrigerant, you'll never have to worry about it being affected by the mandatory phaseout of chlorine-based CFC and HCFC refrigerants.

The right refrigerant, however, is only half of the equation. Chiller reliability is just as important, outweighing other considerations, including first cost and energy efficiency. Why? Because of the high cost of unexpected downtime in your facility.

But will the 17EX really operate more reliably, resulting in greater value to you and your operation? Absolutely. And here's why…

Compressor Design Ensures Reliability

Our engineers took the best features of Carrier's industrial chillers and applied them to the 17EX, providing you with the optimum solution for your chillers needs.

Steel-Backed, Babbitt-Lined Bearings. The bearings' steel backing provides the structural support needed to absorb high radial and axial loads, while the babbitt lining protects the shaft from scoring should there ever be a lubrication failure.

Epoxy-Coated Compressor Casting. Keeps impurities out of the lubrication system.

Tilting-Pad Thrust Bearings. For superior handling of axial forces, this Kingsbury-type bearing's eight floating pads automatically align in a wedge formation to ensure load-carrying surfaces are separated by a thick film of lubricant - even during accidental reverse rotation - increasing bearing life.

Double Helical Gears. Double helical gears transmit higher horsepower loads more smoothly, eliminating the thrust load generated by the gears during the transmission of larger horsepowers. The patented Carrier Dynapoise® transmission has been proven in over 25,000 applications.

Hermetic Motor. Eliminates a host of problems associated with open-drive designs, including shaft seal leakage, shaft alignment problems, high noise levels and machine room cooling requirements, And since it's refrigerant-cooled, it's more efficient, smaller, lighter, and requires less inrush current.

Open Drive Flexibility. The 17EX centrifugal chiller features an open drive compressor design. A wide variety of electric motor and turbine options are available to match the most efficient driver choice for your application.

Superior Energy Efficiency

Utilizing time-proven technologies, the 17EX makes the most of your energy dollar thanks to its exceptional efficiency under a broad range of operating conditions.

Two-Stage Design. The 17EX chiller offers a two-stage, economized cycle with and integral refrigerant sub-cooler in the condenser, Combined with aircraft quality inlet guide vanes and the latest heat transfer technology, efficiencies up to 10% better than single-stage units are achievable.

Float Valve Control System. This superior system maintains the optimum refrigerant level in the cooler under any load condition, increasing chiller efficiency across the entire operating range. Stability is assured at different high-load, low lift and low-load, high lift conditions. The 17EX can utilize condenser water temperatures as low as 55F, providing up to 25% more than nameplate tons with efficiencies as low as .40 kW/ton.

Heat Exchanger Designed For Long Life

Although the compressor is the most critical part of any chiller, it isn't the only components that impacts system and reliability.

ASME-Certified Heat Exchangers. 17EX heat exchangers are ASME Certified on both the refrigerant and water sides. Independent inspectors not only review design calculations, they inspect each weld, rejecting any work that's not up to stringent ASME standards.

Skip-Fin Tube Design. Our units utilize tubes with a unique Skip-Fin Tube Design that eliminates internal and external finning where tube comes in contact with support sheet, creating a superior bond. And because the tube is thicker where it isn't finned, the possibility of tube failure due to vibration and wear is greatly reduced.

Double-Grooved Tube Sheets. Each tube is expanded, then rolled into the Double-Grooved Tube Sheets, forming a leak-tight seal between water and refrigerant. Cooler tubes are also expanded into the closely-spaced intermediate support sheets, locking the tubes securely in place within the heat exchanger's volatile environment.

Modular Design For Easy Installation

Carrier understands the importance of easy installation, especially in chiller replacement. Our 17EX chiller was designed to make installation fast and trouble-free.

Single-Piece Modular Construction. Single-piece shipment ensures leak-tight integrity and eliminates costly, time-consuming field assembly for new projects. Bolt-together, modular construction makes it ideally suited for replacement projects, where ease of disassembly and reassembly is critical to reducing installation time and expense.

Simplified Operation And Maintenance

Microprocessor Control System. A state-of-the-art, user-friendly control system makes machine operation and maintenance simple. And the 17EX chiller's product integrated control (PIC) feature allows full system integration with the Carrier Comfort Network.

Bearing Access Cover Plate. Provides easy access to the double helical gears, split-sleeve journal bearings and tilting-pad thrust bearing. Technicians can quickly check tolerances and actually remove bearings to check surface wear without compressor disassembly, saving you time, money and reducing the likelihood of a catastrophic failure.

Optional Marine Water Boxes. Marine Water Boxes are available on both cooler and condenser, so field-installed piping doesn't have to be removed for tube cleaning. The Float Valve Flow Control System is also fully accessible through flanged bolted covers.

Integral Refrigerant Storage Vessel. Allows the 17EX to stand alone in a machine room that incorporates different refrigerants, eliminating refrigerant mixing and contamination as well as the costs associated with purchasing, installing and maintaining remote storage systems. Now that's added value!

Once you see the big picture, it's easy to see why - when it comes to quality, reliability and value - carrier's 17EX is setting a new standard. But that shouldn't be surprising… after leading the industry for more than 75 years, we're not about to stop now!
