(*) Thanks to the high performance of Irsap TESI 3 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 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
