AERCO's Benchmark Boiler is designed for condensing application in any closed loop hydronic system. It delivers unmatched burner modulation to match energy input directly to fluctuating system loads to yield the highest possible seasonal efficiency. No other product packs as much capacity into such a small footprint.
To minimize emissions, Benchmark boilers are fitted with a low NOx burner whose emissions will meet the most stringent NOx and CO requirements. The fully modulating burner also maintains AERCO standards for energy efficiency, longevity, reliability and construction quality.
The Benchmark Series comes standard with AERCO’s Patent Pending, Oxygen Level (O2) monitoring system. This monitoring system, designed to display the O2 level directly on the unit in real time, can also be remotely monitored via Modbus giving the customer the ability to measure the emissions level and fuel economy of the boiler without traditional combustion calibration devices.
Benchmark boilers can be used as an individual unit or in modular arrangements and offers selectable modes of operation. In addition to controlling the boiler according to a constant set point, indoor/outdoor reset schedule or 4-20mA signal, one or more units can be integrated via Modbus communications protocol. For boiler plants ranging from 2-8 boilers, AERCO’S built-in Boiler Management Sequencer* can be utilized. For heating plants greater than 8 boilers, the ACS (AERCO Control System) provides the right solution. Likewise, Benchmark systems can be easily integrated with a facility-wide Energy Management or Building Automation System.
Available in seven models ranging from 750,000 BTU/hr to 6 million BTU/hr
High Efficiency – up to 99%
Stainless Steel Firetube Heat Exchanger
Low NOx and CO Emissions
Designed and Manufactured in the USA
First introduced in 1997, the Benchmark boiler is one of the first high-efficiency products available in the U.S. The market leader for the last decade, several thousand Benchmark units have been installed throughout North America and have continued to operate flawlessly season after season. Their performance proven reliability can be credited to:
Superior Construction Materials
A new 439 stainless steel heat exchanger offers even longer life and improves longevity with a simplified design that has only two moving parts.
Advanced Design and Components
AERCO’s patented air/fuel delivery system and fully modulating burner reduces cycling losses, as well as wear and tear.
AERCO stands behind its products. The heat exchanger in the Benchmark boilers has a 10-year full (non-prorated) warranty.
Benchmark products provide a number of venting options. Sidewall, through-the-roof, and ducted combustion capabilities (direct vent), approved for venting with Polypropylene, or AL29-4C materials, are all available and provide broad installation flexibility and savings.
All Benchmark products are delivered as a single, fully assembled unit. Its small footprint, doorway size, and quiet operation make it ideal for both new construction and retrofit applications.
Zero Side Clearance
The redesigned Benchmark can be serviced via the front or top of the boiler, as well as the side. This flexibility allows units to be configured side-by-side.
The Greenspec® Listed Benchmark boilers are perfect for “green” designs. Their small footprint, flexible venting/piping options, high efficiency, and lower operating costs can help facilities earn LEED points. Benchmark has been designed with environmental advantages:
O2 monitoring system
Benchmark units are available with AERCO’s proprietary O2 monitoring system, which displays the oxygen level directly on the C-More controller in real time. It can be monitored via Modbus, so customers can measure emission levels and fuel combustion efficiency to maximize fuel economy.
Low NOx burner
Benchmark boilers are fitted with a low NOx burner whose emissions consistently meet the highest regulatory standards. Ultra low NOx (9 ppm or less) calibrations are available.
Efficiency and operation is further optimized via the C-More Touch Screen Control System. Intuitive, advanced, and simple to operate, C-More combine’s temperature and operating controls, combustion safeguards and fault enunciator functions – all at your fingertips! Benefits include:
Simplifies diagnostic troubleshooting
Full integration with BAS and EMS systems
Supports remote monitoring and control
Ensures fail-safe boiler operation (if external building controls fail).
Remote Data Collection
AERCO’s remote data collection continually monitors the internal operations of your AERCO equipment, scanning performance parameters and potential fault risks. This information, transmitted via Internet, is collected and evaluated at our data center. Our data center has the capability to monitor performance trends and fault occurrences. Future capabilities include early warnings before faults occur and email alerts to the user.
Boiler Management System
Benchmark boilers can be used as an inpidual unit or in modular arrangements and offers selectable modes of operation. In addition to controlling the boiler according to a constant set point, indoor/outdoor reset schedule or 4-20mA signal, one or more units can be integrated via Modbus communications protocol. For boiler plants ranging from 2-8 boilers, AERCO’S built-in Boiler Management Sequencer can be utilized. For heating plants greater than 8 boilers, AERCO’s ACS (AERCO Control System) provides the right solution. Likewise, Benchmark systems can be easily integrated with a facility-wide Energy Management or Building Automation System.
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.
Secondary Low Water Cut-Off (LWCO)
Where required by building code. Secondary LWCO must be installed external to boiler.
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.
