HTS Eclipse – RatioAir Single Burner Series

Overview

The Honeywell RatioAir is a family of single gas burners with integrated air/gas ratio control, covering a wide range of heating capacities from 25 kW to 2,000 kW. Each model uses a fixed-ratio mixing principle that proportionally controls gas flow in relation to the combustion air volume, delivering stable and repeatable combustion performance across the entire firing range.

RatioAir burners are engineered for industrial and commercial heating applications where compact installation, reliable ignition, and consistent air/fuel ratio control are required. The series is available in eleven capacity sizes and is supported by an extensive range of spare parts for long-term serviceability.

Features & Benefits

• Integrated air/gas ratio control using a fixed-ratio mixing principle — maintains consistent air/fuel ratio across the full modulation range without a separate ratio controller
• Wide capacity range from 25 kW to 2,000 kW — eleven model sizes to match specific application heat requirements
• Compact single-body design — simplifies installation and reduces panel space requirements
• Suitable for natural gas and other specified gas types — verify compatibility with the relevant model data sheet before commissioning
• Designed for modulating operation — supports variable firing rate for efficient combustion control
• Comprehensive spare parts availability — individual spare part lists published for each model size
• Supported by full operating instructions and technical information documentation
