HTS Eclipse Direct Fired Furnace Burners – Furnnox
Need help selecting your product?
The Honeywell Eclipse Furnnox burner series delivers ultra-low NOx performance for direct-fired, high-temperature process heating. Using staged-air, nozzle-mix combustion, Furnnox produces a stable flame with excellent on-ratio control across a broad turndown, making it ideal for furnaces that require tight temperature control and low emissions.
Features & Benefits
- Ultra-low NOx operation (typ. <30 ppm @ 3% O2) for cleaner compliance.
- On-ratio control across the operating range for high thermal efficiency.
- Nozzle-mix design with staged combustion air for reduced NOx.
- Supports natural gas, propane, or butane fuel service.
- Rugged industrial construction; integrated gas/air orifices simplify set-up.
- Suitable for continuous or intermittent operation in direct-fired systems.
