Fireboxes
ADVANTAGES OF SUPRA FIREBOXES AND INSERTS
QUALITY COMBUSTION
SUPRA has developed a technology known as “hot combustion + 150°C”.
It is based on the principle of “concentrating the heat” in the firebox,
thanks to the insulated smoke baffle. The temperature in the combustion
chamber can thus be 150°C higher than with traditional combustion.
More heat is radiated through the glass, which means the heat is released
faster and more effectively.
> The combustion is complete, with clean smoke (low emissions), and the
appliance is more efficient.
> Maintaining the firebox is easier too, as there is less ash. The bistre and
smells, symptoms of “cold combustion” are absorbed.
> The glass stays clean for longer: this is the “pyrolysis” effect (self-cleaning
of soot at 500°C on the inside of the glass), which comes into play on top
of the “clean glass” system.
LIFT UP DOORS
SUPRA has chosen to use a “synchronised double chain lifting” system for
its fires with a lift-up door. This ensures themovement of the door remains
silent and smooth over time. The door’s trajectory is designed to avoid
any friction between the seals and the fixed frame. As it is raised, the door
automatically moves away from the frame and comes back into contact
with it in the top and bottom position to guarantee a tight seal.
CONNECTION OF THE COMBUSTION AIR
Dependingon the insulationandequipment in thehouse, the combustion
air must be taken from outside the room. SUPRA has created the «IN’AIR»
module (compatible with mechanical ventilation systems) to take air from
outside the room.
It does not interfere with the operation of the fire, output is optimised and
comfort is improved.
THE TRIPLE ENVELOPE COMBUSTION CHAMBER 2+1
This is the ideal solution to guarantee the lasting, performance and
continued safety of the firebox. Consisting of an airtight double wall (steel
+ cast iron + firebrick), it diffuses the heat more quickly. A third safety wall
(included as standard or optional) made of reflective steel protects the
firebox’s environment against overheating.
THE “CLEAN GLASS” SYSTEM
The “clean glass” system developed by SUPRA is based on the circulation
of air along the vitroceramic window (resistant to 800°C). The door
frame channels air along the window which repels the smoke (optimum
effectiveness at nominal burning speed). The glass stays clean for longer.
This air also provides more oxygen for the flames and contributes to clean
combustion.
