Arpa 12 Horizontal

ARPA 12 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 powers from 115 to 3394 Watt.

Thanks to the high performance of Irsap ARPA 12 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
