We've re-engineered our two-million BTU/hr. condensing boiler! Measuring just 79”H x 28”W x 36”D, the secret behind the unit’s compact size is an enhanced heat exchanger design. In addition, the BMK2.0LN now requires just 120V of electrical power and 4” gas pressure to operate.

• 99+% Operating Efficiency
• Compact, Easy to Apply Design
• <30 ppm NOx Capabilities

20:1 Modulation Delivers Up to 99+% Efficiency

As a condensing boiler, the thermal efficiency of the BMK2.0LN increases when applied in a system that leverages cold return water temperatures. But it's the unit's unmatched 20:1 turndown that really maximizes operating efficiency and seasonal fuel savings. Comprehensive tests are being conducted to confirm the unit's efficiency over its entire 100,000 to 2 million BTU/hr. operating range. The initial boundary tests indicate that efficiency up to 99.3% can be achieved when the unit operates at its lowest firing rate (5% input) with 60°F inlet water temperature. Even at full fire (100% input) the BMK2.0LN delivers 85.3% efficiency.

Compact, Easy-to-Apply Design

Measuring only 79" high x 28" wide x 36" deep, the BMK2.0 LN 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 BMK2.0LN 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. 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 II (BMS II) for multiple unit installations.

<30 ppm NOx Capabilities

Certified by the South Coast Air Quality Management District (SCAQMD) and the Texas Commission on Environmental Quality (TCEQ) in its class, BMK2.0LN boiler is equipped with a low NOx burner and fuel delivery system that ensures emissions consistently measure <30 ppm of NOx corrected to 3% excess oxygen at all firing rates.

PRODUCT OPTIONS

IRI Gas Train - Incorporates two safety shut-off valves in a single valve body with normally open vent valve.

ACCESSORIES

Secondary Low Water Cut-Off (LWCO) - where required by building code. Secondary LWCO must be installed external to boiler.

CONTROLS

AERCO C-More™ Control Package - Standard controller supports constant set point, remote set point and/or outdoor reset schedule for individual boiler operation. Offers step-by-step diagnostic menus and status displays to help users set controls and check faults. More than 40 distinct messages, written in easy-to-understand language, convey subsystem status throughout the start-up sequence and during operation. The flash-upgradeable platform can be remotely monitored, controlled and upgraded via Modbus protocol using the RS-232 or RS-485 connection . The system provides failsafe and independent operation in the event of external building control system failures.

Communications Gateway - optional accessory supports boiler or BMS integration with BACnet, LonWorks and N2 systems.

AERCO BMS II - optional multiple unit controller recommended for installations of two or more boilers to maximize operating efficiency.
