Features & Benefits:
- Compare RatioMatic burner features to any competitive model
- RatioMatic burner design takes the guesswork out of start-up and adjustment
- Ratio regulator automatically compensates for changes in operating conditions
- Turndown range of up to 90:1 depending on the burner size and chamber conditions
- Direct-drive air butterfly eliminates linkages which can slip or jam during operation
- Fast-mixing nozzle provides clean stable flame at all firing rates and releases heat into the chamber, not the oven wall
- Ideal for emission-sensitive processes due to low NOx, CO and aldehydes
- Capacities from 500,000 to 30,000,000 Btu/hr
