Benchmark Standard 750 and 1000

The Benchmark Standard 750 and 1000 commercial condensing boilers deliver the highest burner turndown in the industry to achieve the highest seasonal efficiencies. They come 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 monitor the boiler performance in the areas of emissions and fuel economy without traditional combustion calibration devices.

 

 

Features and Benefits

Now, even the smallest hydronic projects will be able to cost effectively leverage the fuel savings and operating reliability of a condensing, fully modulating boiler backed by a market-proven design. In addition, the Benchmark 750 and 1000 require just a 120V of electrical power and 4” gas pressure to operate.

  • 99+% Operating Efficiency
  • Compact, Easy to Apply Design
  • <20 ppm NOx Capabilities
  • Standard Controls Package

20:1 Modulation Delivers Up to 99+% Efficiency
As a condensing boiler, the thermal efficiency of the Benchmark  750 and 1000 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 50,000 to 1 million BTU/hr. operating range. The initial boundary tests indicate that efficiency up to 99+% 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 Benchmark 750 and 1000 delivers 87.2% efficiency.

Compact, Easy-to-Apply Design
Measuring only 79" high x 28" wide x 25" deep, the Benchmark 750 and 1000 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 Benchmark 750 and 1000 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.

<20 ppm NOx Capabilities
Benchmark 750 and 1000 boiler is equipped with a low NOx burner and fuel delivery system that ensures emissions consistently measure <20 ppm of NOx corrected to 3% excess oxygen at all firing rates. 9 ppm NOx are capable and South Coast Air Quality Management District (SCAQMD) and the Texas Commission on Environmental Quality (TCEQ).

Standard Controls Package
The AERCO C-More™ Control Package supports constant set point, remote set point and/or outdoor reset schedule for inpidual 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.

Options and Accessories

Product Options

Reduced NOx Levels
AERCO recommended calibration points can be re-set to support applications that require reduced NOx emissions levels 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.


Accessories

AERCO Control System (ACS)
Optional multiple unit controller recommended for installations of two 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.

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

Integration Panel 
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.

Sentinel Products
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.
