CRITICAL CLEANING CRITICAL CLEANING DEMANDS GOODWAY. DEMANDS GOODWAY. LIVING Wild CHILLER TUBE CLEANERS FOR SMOOTH AND ENHANCED TUBES Goodway’s line of Ream-A-Matics® makes tough tube cleaning a simple, one-person operation. Each machine can use a variety of quick connect brushes and cleaning tools mounted to the tip of a rotating flexible shaft, along with a simultaneous water flush, to remove deposits. Both electric and air powered units are available, as well as units with reversible shaft rotation, a shaft feeder gun, chemical injection, and a 500 PSI power flush. So the next time you need to clean your chiller — clean it the good way.

Input 93 at www.esmagazine.com/instantproductinfo Matches AC System Output to Changing Loads, Maintains Comfortable Humidity Levels Most AC systems lack subtlety: they either run at full capacity or they’re off. Under low load conditions, most systems quickly cool the air and then shut down, allowing humidity to build. The APR Control lets AC systems operate at less than full capacity so they continue to dehumidify without overcooling. ■ For retrofits or new DX systems to 100 tons ■ Ideal for makeup air and VAV systems ■ Fast, simple installation Similar to its neighbors, the Museum receives most of its electricity from hydroelectric power, generated at Niagara Falls and supplied to the Adirondack region. A 40 kW photovoltaic array on the roof of the building supplies the Museum with 10% of its daily power as well. During a regional blackout, however, the Museum needs 24/7/365 back-up power to maintain its living animal exhibits. So when electrical power to the building and its array are not available, the Museum’s expandable, standalone emergency back-up power system, which consists of a 1,000-kW generator, keeps all Museum operations online. Residents of the Adirondacks use electric power to heat their homes as well, as the area is void of natural gas lines. Due to the size and energy demand of the Museum, though, using electric power as heat was not an option. Instead, the Museum employs propane tanks. Five interconnected, manifold 1,000-gal tanks combine to meet the Museum’s winter heating demand. During extreme conditions, the gas can be exhausted in as little as five days. Propane was chosen, for its availability and supplier proximity to the Museum. ES Gasparec is senior vice president with the Syska Hennessy Group (New York).
