by Rebecca Walker — April 15, 2009—AERCO International, Inc., a leading supplier of commercial boilers and water heating products, introduces a newly designed Benchmark 2.0 Low NOx (BMK2.0LN).
The two-million BTU/hour condensing boiler has been re-engineered to deliver a smaller footprint and reduced electrical consumption while maintaining unmatched 20:1 turndown to maximize seasonal fuel savings. Consulting engineers and contractors can employ the environmentally-friendly, high-efficiency boiler in a wider variety of hydronic heating applications than was previously possible due to the new design.
Measuring just 79″H x 28″W x 36″D, the re-designed BMK2.0LN boiler occupies a mere seven square feet of floor space, says the company. “The secret behind the unit’s compact size is an enhanced heat exchanger design,” said Peter Rimassa, AERCO Business Segment Manager. “AERCO engineers were able to reduce its size without sacrificing thermal efficiency.”
The new design employs the same pre-mix air/fuel delivery system including a variable speed blower that is featured in other models in the Benchmark family of boilers.
The new BMK2.0LN boiler maintains the reliability and performance that have helped make the Benchmark family the market leader since its introduction in 1997. With a 20:1 operating range of 100,000 to 2 million BTU/hr., the BMK 2.0LN precisely matches fluctuating loads to minimize boiler cycling and eliminate temperature overshoot. The boiler achieves very high thermal efficiencies when it’s firing at its lowest rates, so the BMK 2.0LN is most efficient during part load operations, which characterize most of the heating season. In fact, the boiler achieves 99.3% efficiency at its lowest firing rate (5% input with 60F inlet water). At full fire with 160F inlet water, the BMK2.0LN delivers 85.3% efficiency.
