FERROLI LIMITEDFerroli began producing heating appliances and equipment in Italy
during the 1950s. Today, the company is still family-owned but now
operates ten ultra-modern factories in Europe, employing over 2,500
people and producing a wide range of wall hung, cast iron and welded
steel boilers, making Ferroli one of the largest and most successful
heating appliance manufacturers in the world.
FERROLI COMMERCIAL AND INDUSTRIAL BOILERSThe commercial and industrial boiler range covers wall hung and floor
standing steel and cast iron designs, condensing, atmospheric, pressure
jet units, gas and oil models. Outputs range from 50kW to 14,000kW.
Other products include heat pumps, cylinders, solar heating and
plate heat exchangers. Ferrolis UK warehouse, backed by its huge
manufacturing facility in Italy, offers delivery ex-stock for most smaller
boiler models and for all frequently used parts. It also assembles and
commissions sectional boilers in the UK to suit particular requirements.

Features and Benefits
The shape design of the heat exchanger ensures an optimum ratio between the combustion volumes and the heat exchange surfaces
The materials used ensure the long life of the boiler
New turbulators improve the heat exchange of the flue gas and at the same time ensures a lowerpressure drop
A baffle plate has been fitted at the central heating system return inlet to improve the circulation ofcold water towards the bottom of the boiler. This solution ensures more uniform distribution of theheat exchange fluid across the boilers heat exchange surface, achieving maximum heat exchange with less stress on the walls
The tube bundle has been positioned above the combustion chamber, so that the flue gas is alwaysdischarged into a hotenvironment, preventing condensation forming
The burner is not aligned with the combustion chamber, but rather has been moved downwards. This assists the reversal of the flame, reduces the pressure drop on the flue gas side and as aconsequence extends the operating range of the generator
The combustion chamber is completely cooled (even at the rear), to ensure a greater heat exchangesurface and improve the distribution of the heating load across the walls
The steel body is completely lined with an 80mm thick layer of glass wool, in turn covered by a sturdylayer of tearproof material
The door can be hinged on the right-hand or left-hand side, has a double door stop with a new-concept locking and centring system. The door lining in the Quadra is made from ceramic fibre
The PREXTHERM RSWQuadra series heatgenerators arepressurised combustionboilers with flamereversal in thecombustion chamberand three flue gas passes.

Features and Benefits
The shape design of the heat exchanger ensures an optimum ratio between the combustion volumes and the heat exchange surfaces
The materials used ensure the long life of the boiler
New turbulators improve the heat exchange of the flue gas and at the same time ensure a lowerpressure drop
A baffle plate has been fitted at the central heating system return inlet to improve the circulation ofcold water towards the bottom of the boiler. This solution ensures more uniform distribution of theheat exchange fluid across the boilers heat exchange surface, achieving maximum heat exchange with less stress on the walls
The tube bundle has been positioned above the combustion chamber, so that the flue gas is alwaysdischarged into a hotenvironment, preventing condensation forming
The burner is not aligned with the combustion chamber, but rather has been moved downwards. This assists the reversal of the flame, reduces the pressure drop on the flue gas side and as aconsequence extends the operating range of the generator
The combustion chamber is completely cooled (even at the rear), to ensure a greater heat exchangesurface and improve the distribution of the heating load across the walls
The steel body is completely lined with an 80mm thick layer of glass wool, in turn covered by a sturdylayer of tearproof material
The door can be hinged on the right-hand or left-hand side, has a double door stop with a new-concept locking and centring system. The door lining in the Tonda has a double cement lining plusan extra layer of insulating material
Prextherm RSW TondaPressurised steel boilers
