ELLPREXPressurised steel boiler for gas, oil or heavy-oil pressure jet burners, with floating furnace from the model ELL 730 up to the model ELL 3500
Reversed flame combustion chamber Elliptic furnace up to the model 970 kW Highly condensate resistant thanks to:
Misalignment of the furnace against the outer shell For the models ELL 730 to 3500 the furnace, welded only to the fron tube plate, is free to
dilatate Patented fin effect on the welding seams of pipes onto the rear tube plate
Silent operation thanks to low counter pressure on smoke side High mechanical resistance thanks to floating furnace Anti-condensing helicoidal turbolators Heat losses reduction, due to the strong insulation (80 mm) with rock wool of the boiler body
and (up to the ELL 970), to the ceramic fibre insulation on the door (-30% of radiation losses) Adjustable door with double opening (left and right) Approval as boiler with adjustable output External panel board with mechanical control and safety thermostats (as an optional extra an
outer compensator can be supplied) Easy installation Constrtuction according to the EN 303, part 1. Maximum Working Pressure: 6 bar (for models ELL 1100 up to 3500 it is possible, under
specific request, to provide a MWP up to 10 bar) Two bulb holders, capable to accommodate 3 bulbs eachS model Same features as the standard model, but provided in bulk for assembly in boiler house (up to
the model 970 kW)* N.B.: if case the heavy oil, with a max viscosity of 7°E at 50°C, is used, there will be a 13% reduction of the max declared input.
