STAMFORD, Conn. – According to a recent survey by Goodway Technologies, many facility managers have cooling tower maintenance programs in place, but many aren't sure they are doing enough. Routine maintenance on cooling towers can often be overlooked or seen as labor intensive, which is why Goodway is hosting a free webinar to educate participants on the impact of neglecting cooling towers and provide tips on how to execute preventive maintenance. The webinar, “Preventative Maintenance for Cooling Tower Systems,” will take place at 2 p.m. EST on Tuesday, June 12. Goodway's liquid solutions expert, Ray Field, will discuss the importance of cooling tower maintenance for facilities and public health. In addition to the important health aspects, proper cooling tower maintenance helps to maintain overall system efficiency and reduce operational costs. Webinar participants will learn about the development of a preventive maintenance plan and the proper maintenance steps. With the introduction of ASHRAE Standard 188-2015, cooling tower maintenance continues to be a top priority for facility managers and leadership. The Centers for Disease Control and Prevention reports there were about 6,100 cases of Legionnaire's disease in the United States in 2016. Field is a chemical engineer and certified water technologist with over 25 years of experience in water treatment and chemical products development. Field serves as director, liquid solutions for Goodway Technologies. He specializes in developing diversified chemical technologies, product management and business development.

Greenheck make-up air models DGX and MSX can now be configured with a direct drive, mixed-flow plenum supply fan for low- to medium-pressure applications. With performance capacities from 800 to 16,000 cfm, Models DGX-P-MF and MSX-P-MF reduce horsepower requirements, resulting in lower operating costs. The direct drive, mixed-flow impellers contribute to lower sound levels; sound power reduction of up to 8 decibels can be achieved. The factory-mounted, preprogrammed variable frequency drive provides an inherent soft-start for the supply fan, while the absence of belts and sheaves also reduces maintenance and simplifies air balancing in the field. Multi-directional discharge contributes to installation flexibility. Heating options include direct gas-fired, electric heat, hot water and steam coils; cooling options include packaged-direct expansion, split-direct expansion, chilled water and evaporative cooling. Models DGX-P-MF and MSX-P-MF are ideal for a variety of commercial and industrial facilities where low sound and energy efficiency are required. For more info, visit www.greenheck.com. [...]

COLUMBUS, Ohio – Heating, Air-conditioning & Refrigeration Distributors International released its monthly TRENDS report, showing average sales for HARDI distributor members increased by .2 percent in March 2018. The average annualized growth for the 12 months through March 2018 is 6.1 percent. “March is a transition month,” said HARDI Market Research & Benchmarking Analyst Brian Loftus. “There was almost 10 percent more heating degree days, but it appears that was primarily a reason to delay cooling equipment purchases.” “The first quarter earnings reports will be the first full look at post-tax reform profitability for U.S. businesses,” said HARDI Senior Economist Connor Lokar. “If they struggle to accelerate their profits with the tax change pushing them forward, that would preview the macroeconomic slowdown we expect to bite later this year. The consumer is certainly in a confident and stable position to help drive growth.” “The Days Sales Outstanding, a measure of how quickly customers pay their bills, is near 47 days,” said Loftus. “This is more than a day faster than 2016 and 2017 and more than two days better than 2015.” [...]

Ron MacLean
By Adam FreillThe local rink is a revered space for many Canadians. It's where we gather to build personal character as we play our national sport as kids, and cheer on our hometown heroes as we get older, and it's where you'll find Ron MacLean every Sunday during the NHL season as host of Rogers Hometown Hockey. ”We show up with a little bit of our own story to tell, and connections to the NHL and Hockey Night in Canada,” said the 57-year-old broadcaster during an exclusive interview from his home in Oakville, Ont. ”When we get there, we get bombarded with local lore and legend about the game. It's just really rewarding.” Still playing twice a week at his local rinks, Ron loves the way that dressing room comradery can bring out the best in a group. ”It strips the community of all rank and order. It brings us together and allows us to each be like the other, and to think about the other, and work with the other,” he says. ”Hockey requires teamwork. To me it is the ultimate expression of goodwill. You definitely see it in a rink.” Hitting the iceRon fondly recalls his first steps on a rink, steps that would start his hockey odyssey. ”My father was in the Air Force, so we were stationed in Whitehorse, Yukon, in 1964. We lived a little dwelling called Steelox. It was so cold in the winter that you could see frost heaves where the bolts were on the walls in the inside of the home,” he reflected. ”Across the street, the Clemente family built a backyard rink. They invited me over.” So, like for so many Canadians, on went a pair of bob skates and, with a chair for balance, he took his [...]

Comfort Success with AC
By Gord Cooke Last summer I spent an inordinate amount of time in Florida and South Carolina helping builders and mechanical contractors with high indoor humidity problems. Of course, winter, not summer, is the right time of year for a middle-aged Canadian to be in Florida, and it is usually in winter that I am diagnosing indoor humidity problems in Canada. However, there have been important changes in houses in Florida that are impacting indoor moisture control the summer months, and we should take note to avoid similar problems here in Canada. As you make your way into this year's air conditioning season, it is best to be mindful that true comfort comes from addressing both temperature and humidity. Educate the consumer Speaking with homeowners about the two separate functions of their AC systems – lowering temperatures and lower humidity – may help you lead into other opportunities, such as switching to an energy recovery ventilation system, and ultimately to a whole-house dehumidification system. To put a fine point on those last two items. If a household is currently ventilating with an HRV or a simple exhaust-only ventilation system, installing an ERV would reduce moisture loads by 10 to 15 litres a day on the highest humidity days at very low power consumption. A whole house dehumidifier can remove in the order of 40 litres of moisture from the air each day, at a very efficient three litres per kWh of operation. Seeking comfort The difference between a nice comfortable 23°C, 50% RH indoor condition and a muggy 65% RH is just an extra three to four litres of water dispersed into the air of a typical 2,300 sq.-ft., two-storey home. And a properly sized AC system with correctly adjusted airflows and refrigerant flows needs to operate for at [...]
