Its new fuel-air ratio control system, the company says, is the first microprocessor-based system priced to compete with traditional mechanical cam and linkage assemblies for the commercial-light industrial burner market. The system performs to 0.1° accuracy across two independent fuel firing rate curves for greater efficiency, says the manufacturer. It also reduces setup time. A contractor, for example, can complete setup for a dual-fuel system in 4 to 6 hrs compared to the 8 to 16 hrs when jackshafts are used.
