633 CINQUECENTO [kW 700 ÷ 6.850]

Product catalog summary

Overview: The document details the specifications and features of the new standard H type CINQUECENTO series Low NOx burners, specifically models H455A, H630A, and H685A. These burners are designed for high performance and efficiency with low emissions, achieving Class 2 standards (<120 mg/kWh). They are housed in aluminum with a backward curved centrifugal impeller and have a maximum power output of 6,850 kW.

Specifications: The burners are user-friendly in terms of application and maintenance. The document provides detailed technical specifications, including overall dimensions, power output, and electrical requirements for each model. The models vary slightly in dimensions and power capabilities, with the H685A offering the highest power output.

Technical Details: Each model's dimensions are listed, with specific measurements for various components. The document also includes packaging dimensions and approximate weights for each model. The burners require auxiliary and motor electrical power supplies, with specific voltage and frequency requirements.

Performance Graphs: The document includes graphs showing the relationship between gas output (kW) and pressure, both with and without combustion chamber back pressure. It is noted that to determine the minimum gas pressure at the gas train, the boiler back pressure must be added to the values shown on the curves.

Key Features: The burners are noted for their competitive performance, ease of use, and maintenance. They are designed to meet low emission standards while providing high efficiency and power output.
