Thanks to the high performance of Irsap ARPA 12_2 Vertical 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
