ARPA 18_2 Horizontal represents the aesthetic evolution of the decorative radiator, thanks to its longitudinal development. 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 165 to 3739 Watt.
Construction features
manifolds with a 30 mm diameter circular section
tubes made of sheet steel with an 18 mm diameter
manifold threading 1/2” Gas right
maximum working pressure 10 bar
maximum working temperature 95°C

Thanks to the high performance of Irsap ARPA 18_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 • 1/2” blind plug • piper cover kit • 1/2” air vent
