Arpa 12_2 Horizontal

ARPA 12_2 Horizontal represents the aesthetic evolution of the decorative radiator, thanks to its longitudinal development and the squared profile of the elements. Every caloric need is met by the modularity and breadth of range. There are 15 proposed widths, from 4 to 60 elements in even number and thermal power from 120 to 3388 Watt.

Thanks to the high performance of Irsap ARPA 12_2 Horizontal radiators, the ideal Δt for low temperature projects is Δt at 30°C.

For Δt different from 50°C use the formula: Q=Qn (Δt / 50)n

Standard equipment

wall fixing systems with screws and anchors (not available separately from the radiator)
1/2” blind plug
piper cover kit
1/2” air vent
