Its timeless good looks, elegant and harmonious profile, give TESI great versatility for use in both classical and modern settings.High thermal yield thanks to the considerable water content and the large radiating surface are the characteristics that make TESI ideal for use with the most modern low-temperature systems.

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 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
