The FS-Series are flexible shafts for tube-cleaning machines. The series has been redesigned and improved to be 40 percent stronger and are field repairable, the company said. According to the manufacturer, the new design has the holding power of more than 200 pounds of exerted force. 

The NeoTherm® LC condensing boiler is a fully packaged, 1 million- or 1.7 million-Btu, space-saving hydronic unit that offers 94 percent thermal efficiency. It is a direct vent, sealed-combustion boiler or volume water heater that modulates with a 10-to-1 turndown. 

Over 1,800 companies have reserved more than 375,000 square feet of exhibit space at the Dallas Convention Center for the 2013 Air-Conditioning, Heating, and Refrigeration (AHR) Expo on Jan. 28-30, making it the largest ever held in the Southwest. 

Ranging from an innovative geothermal heat pump to a copper theft deterrent system, the winners of this year’s AHR Expo Innovation Awards represent a broad cross-section of the HVACR industry.

Older cities are loaded with boiler rooms full of steam-heating boilers, and lots of people — knuckleheads included — have had decades to mess with what the “dead men” once lovingly installed. So, here’s a short list of things to look for when you’re troubleshooting one of those old systems, starting in the boiler room.

Available in free-standing or wall-mounted options for indoor or outdoor applications, the Tankless Rack System (TRS) can be ordered, built, and shipped fully assembled, including gas and water manifolds, to any location in the United States and Canada, including the job site, said the company.

Used to heat entire buildings, or as a source of focused spot heating in small occupied areas, the ITH-Series infrared tube heaters have ratings of 40,000-220,000 Btuh. According to the company, the heaters have a 99-plus percent efficient reflector design.

Designed to protect outdoor air conditioning units from theft, both residential and commercial units can be secured with the air conditioner cages. They are constructed of premium-grade steel, and provide the necessary strength for a quality air conditioner cover, the company said.

Significant improvements have been made to the variable refrigerant flow (VRF) zoning R2-Series and Y-Series cooling and heating systems. Industry-leading efficiencies, a smaller footprint, and improved heating startup make these outdoor units ideal for a variety of commercial applications, said the company.
