637 CINQUECENTO [kW 880 ÷ 9.900]

Product catalog summary

Overview: The document details the specifications and technical aspects of the CINQUECENTO series low NOx burners, specifically models K750A, K890A, and K990A. These burners are designed for high performance and efficiency with low emissions, achieving Class 2 standards (<120 mg/kWh).

Specifications: The burners are housed in aluminum with a backward curved centrifugal impeller. They offer a maximum power output of 9,900 kW. The document provides detailed dimensions and configurations for each model, including boiler drilling and burner flange specifications.

Technical Details: Each model has specific power ranges, auxiliary and motor electrical power supplies, fan motor specifications, gas connections, and noise levels. For instance, the K750A model ranges from 880 to 7,500 kW, while the K990A ranges from 1,820 to 9,900 kW. All models operate with a noise level below 85 dBA.

Graphical Data: The document includes graphs showing the relationship between gas output (kW) and pressure, highlighting the need to consider boiler back pressure for accurate gas output readings.

Packaging and Configuration: Packaging dimensions and weights are provided for each model, and additional configuration details for the gas train are referenced on other pages.
