Sequenze, Hight 1735 mm, Lenght 500 mm, Ivory - RAL 1013


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.

Angeletti & Ruzza

Sequenze is a heating element that speaks contemporary language: clean, simple forms that blend into architecture with natural ease. This project was designed with practicality foremost in mind: the design radiator can be decomposed to suit the space available. Finding the force of simplicity is harder than it looks, and required long work with the Officina delle Idee Product Development Office to solve all the problems linked to the functionality of the design radiator without compromising the designed shape. In addition to guaranteeing the quantity of heat necessary, we worked hard to hide the connections to the wall to make the model look like it is suspended in air, with proportions and thicknesses that guarantee the expressive force of simplicity.

Thanks to the high performance of Irsap Sequenze 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
