Colors and Finishes
Attention: the colors displayed are indicative and could not be as real radiators.
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
• 4 Universal brakets for Tesi (except for very small batteries)
• 4 connections with reductions 1 “1/4 to 1/2” for Tesi white and colored, mounted on the radiator
• 1 1/2” air vent
• 1 cover for 1/2” blind plug
