BENCHMARK 750, 1000

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.
