AERtrim
Advanced combustion control systems in high efficiency boilers need to maintain precise air/fuel ratios in order to work properly and maximize efficiency. However, environmental variations (such as humidity, atmospheric pressure, filter dust loading, delivered gas energy content and other factors) can often wreak havoc on gas boilers causing them to deviate from the ideal oxygen-fuel ratio.

AERCO’s innovative, patented AERtrim monitors the actual conditions of the Benchmark Platinum and self-adjusts its combustion process to ensure your system is operating at optimal O₂ levels and peak system efficiency. With proper O₂ levels, you’ll have greater uptime reliability, save money with increased efficiencies, produce lower emissions, and create the ideal environment for condensing to occur. You’ll also lowers operating and maintenance costs and receive an additional 1-2% in seasonal efficiency gain. Oxygen levels can be directly displayed on the unit in real time or be remotely moni­tored via Modbus or onAER, giving customers the ability to measure the emissions level and fuel economy of the boiler without traditional combustion calibration devices.

Dual Returns 
With Benchmark Platinum’s Dual Returns, AERCO enables you to take full advantage of your premium Benchmark boiler by helping you design the most efficient system possible.

Most traditional boilers only have Single Returns which limit engineers to designing generic applications that force the blending of hot and cold water temperatures, which create a small Condensing Zone in the Heat Exchanger thereby reducing efficiencies. However, Benchmark Platinum’s Dual Returns allow engineers to take full advantage of diverse load demands specific to a site and design a customized system that maximizes operation efficiencies by keeping cold water separate creating a much larger Condensing Zone thereby enhancing boiler efficiency up to an additional 7%.

Dual Returns are ideal for applications that feature combination systems including, but not limited to Multi-zone space heating, space heating with domestic hot water combination systems, radiant floor heating, pool heating, snow melt, and supplementary heat for heat pump systems.

Industry-Best Warranty
In addition to all the advanced features of the Benchmark Platinum, AERCO also provides the best warranty in the industry:

• 15-Year Heat Exchanger - Thermal Shock, Condensate Corrosion, Manufacturing Defect
• Five-Year Burner
• Three-Year C-More Controller
• Two-Year Parts Warranty

onAER Remote Monitoring
Benchmark Platinum boilers come onAER Remote Monitoring ready and with a 5-year subscription of onAER standard. AERCO’s onAER service is a premiere online service which grants the user remote access to view boiler plant operation and status, track performance and efficiency, and set and view alerts such as faults or maintenance. The onAER service can be set to provide alerts to local trained technicians, offering additional peace of mind, ensuring the utmost uptime reliability and helping you prevent unnecessary wear-and-tear of your equipment as well as premature failure.

Unmatched Modulation and Efficiency
The AERCO Benchmark Platinum (BMK) Water 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 efficiencies. And no other product packs as much capacity into such a small footprint.

Low Emissions
To minimize emissions, the Bechmark Platinum series is 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.

Compact, Easy-to-Apply Design
Measuring only 79' high x 28' wide x 25' deep, the Benchmark Platinum 1500 and 2000 fits easily through a standard size doorway and occupies a very small footprint fitting the most challenging projects as easily as the smallest mechanical rooms. The Benchmark Platinum 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 Sequencing Technology (BST) 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)
The ACS is the best choice for maximizing heating plant efficiency if your heating plant has more than eight boilers or if you are designing a combination control system. There is an ACS relay panel available to provide additional pump and valve control for several combination control configurations.

Motorized Valves
The Belimo F6...HDU Series 2-way butterfly valves are 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. Valves specifically designed for easy installation on BST configured boiler plants are available as well.

Boiler Sequencing Technology (BST) Integration Panel
BST boiler plants have this option available to enable the BST Master to automatically switch a C-More Slave to the BST Master control if the currently designated master is not able to manage the boilers in the plant. The change is automatic so there is no need for a technician to intervene. The C-More may change from a slave to a master if a unit is taken down for service or if there is a fault that disables the C-More currently acting as the BST Master. The panel is the connection point for the Modbus sensors used by the BST Master Control. This allows the signal input of any sensors attached to the Integration Panel to be accessed at any node on the BST communication cables.

AERCO Protonode/Gateways
AERCO offers a multi-protocol, communications gateway to support integration with customers’ building control and energy management systems. The plug-n-play package supports integration with BACnet/IP, BACnet MS/TP, LonWorks, and Johnson Controls Metasys N2 systems. AERCO’s Communications Gateway is available for all AERCO boilers, water heaters and electronically controlled indirect systems.

Condensate Neutralizer Kit
AERCO Condensate Neutralizers are ideal for neutralizing condensate from condensing boilers and furnaces operating on natural gas or propane. The condensate is acidic and has the potential to harm the environment and the sewer system. The AERCO Condensate Neutralizer will raise the pH of the condensate to a more neutral level before it is discharged to drain.

Buffer Tanks
AERCO buffer tanks are ASME certified pressure vessels designed for use with high efficiency, low volume systems that incorporate low-mass condensing boilers. They add thermal mass, dampen fast transitions and minimize boiler cycling that occurs during zero or low domestic load conditions. The AERCO buffer tanks are available in two and four-port (Primary-Secondary) configurations.

Venting Mufflers
AERCO offers 6”, 8”, and 14” exhaust mufflers that are specifically designed with flanged ends to fit directly on the exhaust manifold of Benchmark® Platinum boilers. The flanged-end design allows the muffler to be used with any venting system manufacturer – the only adapter required is an AERCO starter piece at one or both ends of the muffler.
