Detailed Product Description:
MDB Degasser
The MDB Degasser System provides a nominal continuousrefining rate from 15t/h to 75t/h. The system consists of a heated refiningfurnace, one to three spinning nozzles, and PLC automated process and furnaceheating controls.
The MDB furnace is divided into two tofour separate and distinct refining chambers, each equipped with a spinningnozzle mounted to the furnace cover. Each chamber is designed to optimizeprocess gas bubble saturation throughout the melt to maximize spinning nozzlerefining efficiency. An internal baffling system controls the flow of metal,ensuring efficient refining of the molten aluminum as it flows through therefining furnace.
The MDB furnace can be ordered with the following options:
Choice     of immersion heating system.
Hydraulic     tilting system to empty the furnace between casts for cleaning or alloy     changes.
Swivel     mast that both lifts and rotates the cover.
Customized     controls.
MDB Control Panels
MDB provides electrical, inert gascontrol panels, and, if required, chlorine gas panels for all new degassingsystems. FRALCO will also provide new panels for existing degassing systems. 
MDB Electrical Control Panel
The electrical panel isdesigned for your local power supply, fully wired and assembled for operation.It contains all required components for stable process and furnace temperaturecontrol.
MDB Inert Panel
The inert gas/air panelcontains all main and idle inert gas controls. All pressure regulators,pressure gauges, valves, and instrumentation for the control of inert gas aresupplied. When needed, cooling air and cover gas controls are included in theinert gas panel. Flow meters or flow controllers can be supplied as optionalequipment and communication modules between the electrical panel and thecustomer’s internal communication devices are available.
MDB Chlorine Panel
The chlorine panelcontains all pressure regulators, pressure gauges, valves, and instrumentationrequired for proper chlorine flow gas control. An inert gas purge process isincluded in the chlorine gas panel design. Mass flow meters or mass flowcontrollers can be supplied as optional equipment and communication modulesbetween the electrical panel and the customer’s internal communication devicesare available. A chlorine gas leak detector can be supplied as optionalequipment. All piping and instrumentation is designed for the use of chlorinegas follows local standards for hazardous gas processing.
All panels can be customized tomeet customer specifications. FRALCO Field Engineering can provide start-upassistance when requested by the customer. 
MDB -Cartridge Lining
The MDB-Cartridgeis a refractory furnace lining that is easily replaced. When the furnacerefractory needs to be changed, the spent cartridge is lifted by using aspecially designed spreader bar and a crane. After the used MDB-Cartridge isremoved, a new lining can be installed within a few hours.
The one piecerefractory lining is manufactured by FRALCO division under controlledconditions in our pre-cast shapes manufacturing facility. The design using hightemperature refractory and multiple layers of insulation provides maximumservice life and superior insulation.
The lining ispre-fired in our manufacturing facility to remove all moisture. Afterpreheating on site, it is ready to use.
Produced under optimal conditions.
Easily replaceable pre-fired refractory lining.
Reduced man power needed for the relining.Reduced     preheat time. 
All moisture and chemically combined water has     been removed during manufacture.
Downtime of the MDB furnace reduced up to 90%.
