Thanks to the high performance of Irsap Tesi 4 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

• 4 connections with reductions 1 “1/4 to 1/2” for Tesi white and colored, mounted on the radiator • 4 Universal brakets for Tesi (except for very small batteries) • 1 1/2” air vent • 1 cover for 1/2” blind plug
