Honeywell Control LinksHoneywell ControLinks

Honeywell ControLinks Fuel Air Ratio Control System helps you realize real energy savings, increased turndown, reduced emissions and system reliability all in an easy to install, powerful and cost effective package. This microprocessor based control system simultaneously controls from two to four actuators associated with a full modulation power burner. The actuators control the position of primary and secondary fuel valves, combustion air dampers and the FGR damper- if used to provide optimal control and system efficiency throughout the entire firing rate of the system.



Maxon SmartLink MRVMaxon SmartLink MRV

Maxon’s Smartlink MRV system is an electronic parallel positioning system for air/fuel ratio control for use in industrial applications providing a high degree of precision, repeatability and durability. Direct coupled valve and actuator assemblies include weatherproof housing with integrated position feedback and heavy duty planetary gearheads for reliable, long-life operations. The system can store up to 22 point user customized profiles for each actuator. Each Smartlink valve is adjustable to 0.1 degree accuracy and are available with FM approval as non-incentive for Hazardous Locations Class 1, Division 2 , ATEX, and IEC Ex approval.

Maxon’s SMARTFIRE system incorporates air and fuel mass flow meters and allows for fuel totalization and even better control and accuracy.
