Measuring only 79 H x 34 W x 109 D (inches), the Benchmark 5000 and 6000 (BMK5000/6000) features 15:1 turndown for energy efficiency, Low NOx emissions, and high reliability in an unmatched compact footprint that is up to half the size of any other five/six million BTU/hr boiler on the market. Incorporating AERCO’s field-proven stainless steel, fire-tube design, the BMK5000 and BMK6000 provides consulting-specifying engineers, facilities management, and building owners with a boiler that provides flexibility to fit in both retrofit and new construction that require one or multiple five or six million BTU/hr boilers.
Double Block and Bleed Gas Train
Allows real-time cutover from natural gas to propane by rotating the fuel selector switch and changing of logic sticks.
Reduced NOx Level
AERCO recommended calibration points can be re-set to support applications that require reduced NOx emissions level of <9ppm. However, the unit's input rate, performance efficiency and venting requirements will change. Please consult the factory for assistance balancing your efficiency and environmental requirements.
AERCO Condensate Neutralizer Kit
Ideal for neutralizing condensate from condensing boilers and furnaces operating on natural gas or propane.
AERCO Control System (ACS)
Optional multiple unit controller recommended for installations of eight or more boilers to maximize operating efficiency.
BelimoF6... HDU Series 2-way butterfly valves
Designed to meet the needs of HVAC and commercial application requiring bubble tight shut-off for liquids. Typical applications include boiler isolation, chiller isolation, cooling tower isolation, change-over systems, air handler coil control, bypass and process control applications.
Optional accessory supports boiler or BMS integration with BACnet, LonWorks and N2 systems.
Allows for automatic BST Master function transfer to the next available unit in the event the original Master experiences a control panel or communication failure.
Compatible with all materials found in a hydronic loop, these chemicals offer overall protection of a heating system from sludge, scale, corrosion, and freeze conditions.
Secondary Low Water Cut-Off (LWCO)
Where required by building code. Secondary LWCO must be installed external to boiler.
