Schebler says its Sequence Draft Control™ (SDC) design service offers boiler and hot water heater manufacturers a complete engineered venting system. SDC is capable of maintaining the desired condensing dew point of combustion, preventing excess draft which impacts efficiency and fuel/air ratio’s – especially with high turndown modulating burners.
The new MagnaTherm from Laars is a 95% thermal efficiency modulating-condensing boiler or volume water heater available in 2, 3, and 4 million Btu/H sizes. MagnaTherm says it offers a 5:1 turndown, small footprint, slim vertical design with removable top section, a stainless steel heat exchanger, and multiple voltage options to match building service. Designed and made in the U.S.A, the MagnaTherm meets all ASME requirements and is AHRI certified.
The ClearFire®–LC from Cleaver-Brooks integrates the company’s heat exchanger, burner, and control technology into a large capacity condensing boiler product. The CFLC's integrated premix burner and linkageless control, work together to provide full modulation, ultra-low emissions, and optimum turndown, according to company officials.
Ajax Boiler introduced the Triton™ – Atlas Series™ of high-efficiency, near-condensing boilers. The boilers feature up to 86% thermal efficiency and a double row, double pass, high finned copper finned heat exchanger.
Cambridge Engineering has introduced a new line of Blow-Thru® Direct Gas-Fired Space Heaters designed to efficiently and safely heat smaller commercial and industrial facilities. The new line of space heaters, called the Cambridge SA-Series, uses the same technology as the larger ultra high-efficiency Cambridge S-Series, but is sized for smaller applications.
Harsco Industrial Patterson-Kelley has launched the P-K SONIC™ boiler with Duet™ technology. The company claims the P-K Sonic boiler is the first practical stainless steel design for condensing applications in the industry.
Fulton Companies has released a new line of condensing hydronic boilers. The Endura™ boiler is the latest addition to Fulton’s product offerings for the commercial heating market, and is offered in 1.5 million (EDR-1500) and 2 million (EDR-2000) Btus/hr.
Mitsubishi Electric updated its variable refrigerant flow WR2- and WY-Series Modular Water Source Units. Both the WR2- (heat recovery) and WY-Series (heat pump) are available in smaller and lighter units with plate type heat exchangers, and both systems operate in either cooling or heating modes.
Why was one floor’s laboratory ventilation failing to keep up, when it was even the closest floor to the rooftop fans? Some system sleuthing led two engineers to a fitting conclusion. Read more stories in May Issue 2017.
