After spending 2017 in the relative warmth of southern Nevada, the AHR Expo is heading to Chicago’s McCormick Place this month.

The Jan. 22-24 event, one of the largest HVAC construction and sheet metal forming equipment events in the world, is expected to bring over 2,000 exhibitors and more than 65,000 attendees to a show that features products, technologies, seminars and other learning opportunities under one very large roof.

The expo last visited the nation’s third-largest city in 2015. It also came in 2012, 2009, 2006 and 2003.

The show is co-sponsored by the American Society of Heating, Refrigerating and Air-Conditioning Engineers, which holds its winter conference during the event, and the Air-Conditioning, Heating and Refrigeration Institute. An additional 37 other industry associations are also endorsing the three-day event.

“Contractors, engineers and other show attendees always give us high marks for the value our education program delivers, and this year we have surpassed ourselves,” said Clay Stevens, president of International Exposition Co., which organizes the annual event. “The show has become the place where industry professionals can earn CEUs (continuing-education credits), complete certification exams and learn about the latest developments and best practices in free and paid seminars.”

Although much of the attendees’ focus will be on the show floor and the products, organizers note the conference will also feature more than 120 sessions, including free seminars, professional certification opportunities and continuing education programs from the ASHRAE Learning Institute. Sessions include “Building Automation Systems 101,” “Radiant Cooling in the Windy City,” “Global Trends in HVACR,” “Health Impacts of Indoor Air Quality” and “Future of the Billable Hour.”

For ASHRAE members, the society will hold approved courses to help ensure members keep their professional engineer certificates. Each full-day course equals six professional development hours and half-day courses equal three hours.

The society’s technical program will focus on ecological building impacts and integrated design.

“The technical program provides attendees with the information they need to reduce the ecological impact of our built environment on the world around us,” said Michael Collarin, conference chairman. “The program features seven program tracks that focus on resources to design, build, control, commission and operate facilities and infrastructure that need to not only be efficient, but resilient.”

The official ASHRAE hotel for the winter meeting is the Palmer House Hilton.

On the McCormick Place show floor, a number of free, 20-minute presentations on new products and technologies will be offered by exhibitors in special theater areas.

For the full list of sessions and a complete schedule, go to or for the society’s activities.

AHR Expo attendees should expect to see thousands of HVAC and sheet metal products on the show floor at McCormick Place.

At least one exhibitor is using the expo to benefit a charity. After raising money to fight breast cancer at last year’s expo, this year sheet metal accessories manufacturer Duro Dyne Corp. will auction off specially sheet metal machinery to benefit the Wounded Warriors Project. The charity raises funds to support veterans injured since the Sept. 11, 2001, terrorist attacks.

Duro Dyne will be auctioning the PBF510, FPP4 and MF12-A combo, and the FDCC Connector Cradle. The company will donate $1 to the charity every time the hashtag “#DuroDyneWarrior” is used on social media and the company’s AHR booth will have a donation box. Bids can also be emailed to until 5 p.m. EST Jan. 23.

Show officials announce 2018 Innovation Award winners

Products from Setra Systems Inc., Emerson, Danfoss, Calefactio and Spartan Bioscience are among the winners of the 2018 AHR Expo Innovation Awards.

A panel of independent American Society of Heating Refrigeration Air-Conditioning Engineers members evaluated entries based on innovative design, creativity, application, value and market impact, and selected the winners.

The companies and products will be recognized in a ceremony during the expo and the overall Product of the Year will also be announced. Other winners include products from Aquamotion Inc., Chemours, Regal, Fluke Corp. and Triatek.

“Each year, our winners set the bar higher for innovation in HVACR, and this year is no exception,” said Clay Stevens, president of International Exposition Co., producers of the AHR Expo. “We congratulate each of these leaders from across the industry and look forward to seeing their inventive solutions in action at the 2018 AHR Expo.”

The winners in the categories of building automation, cooling, green building, heating, indoor air quality, plumbing, refrigeration, software, tools and instruments, and ventilation are:

Setra Systems, Inc.

Category: Building automation
Manufacturer: Setra Systems Inc.
Product: Setra Flex monitors indoor environmental and ventilation control conditions for operating and isolation rooms, bio-safety laboratories, clean rooms and pressurized critical spaces. Setra Flex is equipped with visual and audible alarms that are configurable and comply with ASHRAE and pharmaceutical industry standards, company officials said.


Category: Heating
Manufacturer: Calefactio
Product: The One is a three-in-one expansion tank, air separator and dirt separator. It eliminates an important number of joints, which limits leaking potential. It also uses less space, takes less time to install comparatively to installing the three devices separately and reduces costs, according to the company.

Stable Vortex II

Category: Ventilation
Manufacturer: Triatek
Product: Stable Vortex II fume hood’s low flow protects chemists from harmful dust and vapors during experiments. It delivers users a safe environment while providing substantial energy savings, the manufacturer said. The Stable Vortex II passes industry tests as manufactured, installed and used.

Copeland Scroll

Category: Cooling
Manufacturer: Emerson
Product: Copeland Scroll is a two-stage compressor from 1 to 10 tons with third-generation technology, officials say. The compressor is used for mid-tier comfort and efficiency rebates with full-load and part-load performance up to 5 percent.

Spartan Bioscience

Category: Indoor air quality
Manufacturer: Spartan Bioscience
Product: Spartan Legionella detection system is an on-site 45-minute Legionella DNA test. The system’s compact format integrates DNA collection, extraction and analysis, the maker says. The system’s technology enables portability with no outside laboratory sample shipment and no technical expertise requirements.

Fluke Corp

Category: Tools and instruments
Manufacturer: Fluke Corp.
Product: Fluke T6 electrical tester tests simultaneous voltage and current measurements without test leads. The T6 now make it possible to take true root-mean-square measurements in crowded junction boxes or along conductors with inaccessible endpoints which saves time, minimizes potential errors and reduces arc flash possibility, the company says.


Category: Green building
Manufacturer: Danfoss
Product: Danfoss Turbocor TTH/TGH High Lift compressor is applicable as an air-cooled chiller and for heat recovery. It also features oil-free, variable speed, magnetic bearing operation for full- and part-load efficiency and green HVAC. This compressor also has low vibration and sound, a small footprint, and reduced maintenance as well as an expanded operating map, the company said.

AquaMotion Inc.

Category: Plumbing
Manufacturer: AquaMotion Inc.
Product: AquaMotion Aqua-Flash is an under-sink hot water recirculation system that has over twice the pipe diameter to prevent calcium buildup. It is equipped with a bypass valve that improves circulation between hot water and the cold line. A bimetal coil closes the internal shuttle bypass port in the value when hot water reaches the valve. The system is standardized to deliver the hot water temperature desired.

Chemours Refrigerant

Category: Refrigeration
Manufacturer: Chemours
Product: Opteon XP44 Refrigerant (R-452A) is a non-ozone-depleting, hydrofluoro-olefin-based refrigerant replacement for R-404A/507 that offers roughly 50 percent reduction in global warming potential compared to R-404A/R-507, according to its manufacturer. The refrigerant provides the closest match to compressor discharge temperature. It also delivers cost-effective options to cut the refrigerant environmental impact in half while following the high global warming potential regulations, officials add.
