MMP MMP molten metal products molten metal products MORGAN MKV MORGAN MKV recuperative bale OUT FURNACE recuperative bale OUT FURNACE HIGH EFFICIENCY The MK V Gas Fired Recuperative Furnace provides the maximum economy in energy costs so far and is constructed using the most efficient low thermal mass materials in the lining. The combination of recuperation, effective conversion to radiant heat transfer and the use of advanced insulating materials provide a melting and holding furnace of exceptional efficiency with comfortable working conditions. By recycling part of the waste energy from the exhaust gasses, typically 35% can be saved. Savings as high as 50% have been seen when replacing some conventional brick lined furnaces. Radiation losses are minimised by the use of a well insulated swing aside cover that can cover the crucible when no baling is needed. The superb insulation allows for excellent melting performance from the compact high efficiency burner. The burner also facilitates improved internal heat circulation and transfer through convection, producing a more even heat distribution around the crucible enhancing crucible life. SIZE RANGE The advanced insulation materials used in the furnace lining result in low casing temperatures, providing comfortable working conditions. Other crucible patterns than those shown in the table are available to provide the capacity span indicated for each size reference. Working conditions are also optimised by very low noise emissions, as the exhaust recuperator also acts as an effective silencer. RADIANT PANEL ASSEMBLIES Twelve high alumina radiant panels surround the crucible and generally extend to the full depth of the furnace chamber. The self supporting and interlocking design provides easy removal, should a panel require changing. These panels efficiently convert gas energy into radiant energy. The MK V Recuperative Gas Fired Bale Out is available in the size range 85kg - 1327kg aluminium. Fuel types The furnace is available for the following gaseous fuels: Natural Gas: Propane: Butane: Dynamic Pressure: Note: 9000 kcals/m³ 22000 kcals/m³ 28000 kcals/m³ 20 - 35mbar Pressures higher than 35mbar will require additional regulation Electrical Supply: 400/415v/480v 3 Phase 50/60hz Size 1/2 230v 1 Phase 50/60 hz Available Recup 01/12.

The dual display programmable digital controller maintains close control, by regulating the heat input to the burner, relative to actual metal temperature and set value. This energy saving and safety feature, enables a lower holding temperature to be automatically selected during periods of non-use. The control panel’s real time clock can be programmed to select reduced temperature and to return to operational value when required. The time clock can also be set to switch the furnace on and off at pre-set dates and times KEY FEATURES Data based on optimum foundry conditions and practices. For typical foundry operations a performance factor of 90% of performance ratings should be assumed. ADVANCED DESIGN The MK V Recuperative Furnace is compact, of robust design and suitable for temperatures up to 850ºc. With the exception of the control panel, it has no separate stand alone components. High reliability is obtained by the avoidance of moving parts such as motorised dampers and use of high reliability components.

Furnace Size Reference Capacity Range Kg Al Working Capacity Power Gas Power Consumption Holding kWh/hr Melt Time (Mins) GAS BURNER The furnace is equipped with a high performance, medium velocity, low Nox., fully proportioning, nozzle mix gas burner. Air is delivered to the burner via a recuperator from a compact speed controlled blower, regulated by a solid state inverter, avoiding valves and linkages. Air and gas are mixed in proportion relative to cold air flows, maintaining ratio across the turn down range. The robust burner is designed to minimise Nox. emissions up to the highest preheat values and conforms to European safety standard EN746 and other world standards.
