(*) Thanks to the high performance of Irsap STEP_B radiators, the ideal Δt for low temperature projects is Δt at 30°C. The heating yields are calculated on products with epoxy powder coatings. For Chrome (code 50) finishes, the yields decrease respectively by 40%. All the available finishes are shown on the facing page.
For Δt different from 50°C use the formula: Q=Qn (∆t / 50)n
Standard equipment
- wall fixing systems the same finish as the radiator
- 2 hidden vent valves of 1/2” and valve caps
- hydraulic connection kit in the same finish as the radiator, complete with couplings for copper fittings (diameter 12, 14 and 15 mm), and multilayer pipes (14 x 2 thick and 16 x 2 thick)

The Designer
When a successful company like Irsap discovers the stylistic synthesis of Antonio Citterio, the result in terms of both aesthetics and performance is impeccable. Our meeting led to the development of a line of authentic design heating elements that speaks the immediately recognizable language of a designer who symbolizes Made in Italy spirit and production. These are products that can be easily inserted in any surroundings thanks to the discretion adopted in their physical configuration. Every single detail has a simple story and a truth to tell: fashion trends come and go without a trace, true design, instead, leaves its mark. Design remains at the disposal of anyone who designs interiors and those who desire to fill these rooms and areas with their own desires and dreams.
