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

METAL TEMPERATURE CONTROL
TEMPERATURE DEPRESSION
The temperature can be sensed from
a floating, fixed or crucible pyrometer.
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.

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.
