AERCO International Inc.: Benchmark Thousand Series high-efficiency boilersHigh-efficiency boilers

The AERCO Benchmark (BMK) Thousand Series of high-efficiency boilers now includes the BMK1500, BMK2000, and BMK2500 for hot water heating systems requiring 1.5 million, 2.0 million, and 2.5 million BTU/h, respectively. Designed for condensing applications in closed-loop hydronic systems, each BMK water boiler is designed with a forced draft, modulating burner, and heat exchanger made from 439 stainless steel, which offers a higher heat transfer coefficient and lower thermal stress coefficient than 300 grade stainless steel. The result is a turndown of 20:1 for the BMK1500 and BMK2000, and 15:1 for the BMK2500, along with greater heat exchanger cycling resistance for high reliability.

Greenheck: Vektor-MS exhaust fanLaboratory exhaust fan

Greenheck’s Vektor-MS inline mixed flow laboratory exhaust fan is designed to reduce fan energy in demand-based laboratory exhaust applications. Featuring Sure-Aire Variable Volume Exhaust (SAVVE) technology, the Vektor-MS responds to changes in airflow and static pressure in an occupied space, causing the fan’s operation to adjust throughout the day based on demand while the variable geometry discharge nozzle modulates to maintain constant discharge velocity at the fan exit. Available in belt or direct drive configurations, the Vektor-MS uses mixed flow impeller technology and a bifurcated fan housing design. Its vacuum shaft seal prevents hazardous or noxious fumes from escaping the shaft opening.
