FIREX 600 PROLONGS THE PLEASURE OF HEAT All Gruppo Ravelli's products have a combustion chamber made from FIREX 600, a vermiculite based material developed by Gruppo Ravelli after long and extensive research. FIREX 600 captures the heat generated by the flames, stores it then gradually releases it, improving combustion quality and keeping the firebox free from combustion residues via a process of pyrolysis.
	The main characteristics of FIREX 600 are: • excellent resistance to high temperatures and the prolonged action of fire • excellent resistance to thermal shock • exceptionally easy maintenance and replacement • good mechanical strength • excellent insulating capacity • no ceramic fibre content • extremely light weight Good resistance to the action prolonged of the fire: It takes about 5 minutes of exposure to an oxyacetylene flame before the FIREX 600 block even begins to show signs of damage. Damage is only visible on the side exposed to the flame, with no sign of overheating on the other side. The block is still whole and perfectly functional.
The graphic explains the temperature difference between a refractory material combustion chamber and a Firex 600 chamber. As the graphic shows, the Firex 600 internal lining allows the combustion chamber to reach temperatures that are 230°C higher in the fire-lighting phase and 100°C higher in the subsequent stove-refilling stages. This is because FIREX retains a greater quantity of heat inside the combustion chamber, for greater stove thermal efficiency. Gruppo Ravelli's FIREX 600 has been examined by the ‘National Institute of Occupational Health, Denmark (AMI)', and is certified free from asbestos and quartz fibres.
