Benchmark 3.0 Low NoX Boiler
From 200,000 BTU/hr. to its full fire input capacity of 3 million BTU/hr., the BMK3.0LN precisely matches fluctuating loads. This incredible range of operation minimizes boiler cycling and eliminates wasteful temperature overshoot. And the operating efficiency of the BMK3.0LN boiler actually increases as the load decreases. In simple terms, at its lowest firing rates (or BTU/hr. inputs), the unit's heat exchanger becomes greatly oversized in proportion to the load - allowing much greater thermal transfer to take place. The means that the BMK3.0LN saves the most energy during part load operations that characterize the majority of the heating season.
Compact, Easy-to-Apply Design
Measuring only 79" high x 28" wide x 64" deep, the BMK3.0LN fits easily through a standard size doorway and occupies a very small footprint. And it fits the most challenging projects as easily as it fits the smallest mechanical rooms. The BMK3.0 boiler supports sealed combustion, ceiling/sidewall venting and low gas pressure applications. Ideal in low flow applications, the unit operates with a small water side pressure drop and can withstand no flow conditions without damaging the heat exchanger. From a controls standpoint, the unit's C-More control system can be integrated directly into a facility-wide Building Automation System via Modbus and is fully compatible with AERCO's Boiler Management System (BMS) for multiple unit installations. 
Performance-Proven Design
Best of all, the BMK3.0LN employs the same parts and technologies that have been performance proven over the past ten years as part of the Benchmark 2.0 boiler line. By rearranging interior components, we've increased the unit's capacity by a million BTU/hr. -- but we've only added 8" to the depth of the original product footprint.
The new design employs two, identical, stainless steel, heat exchangers to deliver the extra capacity. Importantly, this is the same heat exchanger design that has been available with the BMK2.0LN for nearly ten years -- same material, same design, same welding, etc. Whereas, competitive product designs often employ primary and secondary heat exchangers made of different materials to cut corners - we've doubled up on quality with the BMK3.0LN.
