Autoflame Mini MK8 Evolution Module

The Mini Mk8 is Micro-Modulating system that provides an easily programmable and flexible means of optimizing combustion throughout the load requirement range of the boiler/burner.

This control module encompasses all the functions required for reliable burner management. Built into this system is a fully automated flame safeguard and valve proving system, MODBUS connectivity, and a touchscreen interface.

This system ensures the burner temperature is accurate to within 1° C/F and pressure to within 1 PSI. The positioning accuracy of the direct drive motors controlling the air damper and fuel valve is 0.1° throughout the load range. This accuracy ensures repeatable fuel-to-air ratio that leads to improved fuel economy and reduced carbon footprint.
