trol pumps, variable-speed drives, dampers, and other equipment. Victor Cerbins, product manager, commercial boilers, described the ISD’s function this way: “What it does is looks at the supply water to come through the loop, the return water temperature in that loop, and also the flow. So with those three variables, you can determine what your demand really is.” It can control up to 16 boilers. Comfort-Aire by Heat Controller Inc. (www.comfort-aire. com) unveiled its AHBV Series hydronic air handlers. Depending on the model, they are rated either 13 or 14 SEER, have a nominal heating Btuh of 52,00098,500, and a nominal airflow of 600-2,000 cfm. The variable-speed blower motor improves efficiency by adjusting the cfm to match the static pressure of the system. Ready for air conditioning systems of 1.5–5 tons, the hydronic coil has aluminum fin-copper tube construction with manual air vent and drain valves, ¾-inch water connections, and it’s compatible with boilers and water heaters. Grundfos (www.grundfos. com) displayed the Magna wet rotor circulator. The pump is available in three cast iron models and covers flows of 10-170 gpm. The patented AutoAdapt control function automatically adjusts performance to meet demand and save energy. “The pump actually saves, with the AutoAdapt, 70-80 percent of energy compared to a regular pump,” stated Carsten Nørgaard, product manager, large circulators and business development manager. Heat Transfer Products (www. htproducts.com) presented the ModCon modulating and condensing commercial boiler with a 94 percent thermal efficiency. The boiler is available in three models with maximum inputs of 300,000, 500,000, and 800,000 Btuh. It features a load-matching gas burner with a 5:1 turndown ratio to meet variable needs for space heating and domestic hot water in a single application. The direct-vent sealed-combustion boilers can be stacked, two at a time, to double capacity while maintaining the same footprint. Laars (www.laars.com) displayed its Mighty Therm®2 boiler/ volume water heater. Seven models can be used for hydronic systems, volume water heat applications, and as commercial-sized pool heaters. Sizes of 500-2,000 MBtuh can be used with natural gas or liquid propane. One benefit of this line, which is made for the replacement market, is its size. “It will fit through a 30-inch door opening, so that’s ONLINE AT WWW.ACHRNEWS.COM ■ why it’s really good for retrofit work, because we can go through the door. That’s the important thing. If you’re fighting to get one out, you should at least have an easy time of getting one in,” commented Douglas A. DeAngelis, Eastern Atlantic sales manager. Little Giant (www.littlegiant pump.com) introduced a line of shallow pan condensate removal pumps, named 1-, 2-, and 3-ABS. The three fully submersible, in-pan compact pumps automati- cally remove condensate “quickly and efficiently,” according to the company. The pumps have epoxycoated, cast aluminum housings for long-lasting performance. All of the models have a new feature: an advanced nonmercury mechanical switch. “Little Giant changed the switch to accommodate the marketplace,” said Scott Sayton, Little Giant products manager. The switch automatically triggers operation when the condensate in the pan or reservoir reaches a preset level. All of the features of the three pumps add up to convenience for contractors and customers. Another new product from the manufacturer, the Condalert, is an overflow detection device. It is designed for equipment shutdown or warning when leaks and drain overflow conditions are identified. Lochinvar (www.lochinvar. com) introduced its Knight XL modulating/condensing commercial boiler. Features include 94.6-percent thermal efficiency, low NOx emissions, and a fully modulating burner with 5:1 turndown ratio. Five models are available, with 399,000-, 500,000-, 600,000-, 700,000-, and 800,000Btuh inputs. The boiler is equipped for direct-vent installation with air intake and exhaust runs up to 100 feet. The Smart System control offers control and monitoring functions that are easier to understand and use.
