The Mk8 MM Controller is a Micro-Modulating system that offers comprehensive control over industrial and commercial boilers/ burners. It enables users to manage virtually all boiler processes from a single 12.1” multi-touch screen interface without any added modules. The Mk8 MM is ideal for steam and water boilers (watertube or firetube), kilns and steam generators. Designed for oil, natural gas or both fuels, the controller’s linkageless servomotor system and automated flame safeguard create conditions for unmanned boiler house control with remote monitoring and management with Modbus connectivity. The Mk8 MM Expansion Features include: 

• Autoflame Water Level Control
• Analogue Water Level Control
• TDS/Top Blowdown 
• Bottom Blowdown 
• Draught Control 
• Direct Modbus Connectivity 
• First Outs Annunciation 
• Fully Metered Combustion, cross-limited control 
• Steam Flow & Water Flow Metering
• Fuel Change On-the-Fly (COF)

The Mini Mk8 is a cutting-edge Micro-Modulation system that provides easily programmable and flexible means of optimising combustion throughout the load requirement range of the boiler/burner. This control module encompasses all the functions required for reliable burner management. Built-in to this system is a fully automated flame safeguard and valves proving system, direct Modbus connectivity and touchscreen interface. 

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

For decades, boiler houses, manufacturing plants and other industrial environments have relied on our EGA systems to monitor flue gas emissions for the purpose of compliance with environmental regulations and to reduce fuel usage & emissions. The EGA can operate as a standalone, independent continuous monitoring system, or it can be setup to feed back its readings to an Autoflame MM Controller, allowing the MM to trim the combustion; optimising the system’s efficiency & performance. The EGA is capable of: 

• Simultaneous & continuous sampling of up to 6 exhaust gases (O2 , CO2 , CO, NO, NO2  & SO2 ) at a fraction of the price of alternative systems. 
• Operating as a Standalone unit or with Autoflame Mk8 or Mini Mk8 MM. 
• Enabling 3 parameter trim control on a Mk8 or Mini Mk8 MM to improve fuel efficiency and reduce emissions. 

With built-in CEMS Auditing software, view reports by user-definable time periods (24 hours, 2 weeks, 1 month, 3 years, etc.) based on: 

• Total weight & volumetric emissions 
• Weight/volumetric emissions per exhaust gas 
• Total cost of fuel

The Mk8 DTI lets users know in real time how the boilers are performing, either on-site through its built-in touch screen, via local PC, or remotely via a BMS system. It stores MM and EGA systems data for a rolling 3 year period. The DTI is a gateway for communication with the Autoflame MM Controller and EGA range of products. It is capable of collecting and storing information from a maximum of 10 Autoflame Systems in one location, the information gathered is instantly available for transmission to an external source such as a BMS via RS422 or Ethernet link. 

The DTI also includes Autoflame DTI Manager software as standard, allowing data collection over local network or over the internet. It also supports Modbus protocol over Ethernet and RS422 as standard. The DTI can be setup so that Network Emails are generated and sent in the case of a fault or an alarm. The DTI can collect and store information from up to 10 of each of the following Autoflame products: 

• Mk8 MM and/or Mini Mk8 MM Controllers in any combination.
• Autoflame Mk8 Exhaust Gas Analyser (EGA) linked directly to the DTI. 
• Pressure sensors network, Autoflame Mk8 digital Gas or Air Pressure Sensors can be connected and monitored. 
• Mk8 Input/Output modules with both analogue and digital connections.
