Mama, Hight 1400 mm, Lenght 500 mm, Matt White


A couple in both personal and professional life, Silvana Angeletti was born in Rieti in 1969. Daniele Ruzza was born in Rome in 1967. After graduating in industrial design, they began their partnership in February 1994 and opened their own design studio: angeletti ruzza design. They took part in numerous competitions, winning prizes and commendation. They live and work in Rieti and cooperate with numerous prestigious Italian companies. They have been collaborating with IRSAP since June 2006 and their research into proportion and linearity has led to three products that blend artistically into the home environment. SEQUENZE, a radiator that speaks a contemporary language, with a neat and simple form that fits natural into any architectural environment. Shape and function, calm and simplicity are the inspirational muse of the new It Is and M’ama thermo-artworks, made in 2017.


138 Simplicity and substance, purity and emotion: M’AMA is a radiator that best meets not only functional but also psychological and aesthetic criteria. The shape was shaped by the logic of utility and simplicity, rejecting all that is superfluous.

(*) Thanks to the high performance of Irsap M'AMA radiators, the ideal Δt for low temperature projects is Δt at 30°C.

For Δt different from 50°C use the formula: Q=Qn (∆t / 50)n
