APPLIANCE DESCRIPTION

High-efficiency ICI CALDAIE S.p.A. REX F steel boilers must be used for heating systems with water temperature within 60° and
100°C and/or in a system for domestic hot water production, within the limits of their performance and power.
The chosen control panel should be equipped with a safety thermostat with manual reset from 110°C.
They have been provided with cylindrical furnace with reverse flame closed at the back by a fully wet convex bottom, supported
by a stub and that can be coupled with forced draft burners.
Some of the main characteristics of the equipment are listed below:
– boiler body made in quality steel, made up by the front tube plate flanged towards the furnace with RSB process and by the
convex, instead of flat, rear plate, for better resistance to the internal pressure, with laser-cut holes
– cylindrical combustion chamber, with reverse flame, closed at the back with fully wet convex bottom, supported by a stub.
The flame runs through the central part, while the hot gases return peripherally to the front, partially wet, part to be conveyed
to the tube bundle
– EN10217-2 P235GH fire tubes, welded to the front and rear tube plates, equipped with helical turbulators
– rear smokebox made in steel metal sheet, consisting of a single piece that can be easily opened to inspect the fire tubes,
fastened by means of bolts, complete with chimney fitting and cleaning door
– containment tube bundle equipped with connections necessary for the system and the operating equipment, all welded
with approved processes carried out by qualified welders
– casing made with easily removable painted steel panels, that protect the insulation made with high-density fibreglass wool
mats
– front door made in steel metal sheet thermally insulated with ceramic fibre, fitted on hinges, that can be easily opened by
means of drilled ring nuts and with supplied lever.
