Innovation is at the heart of everything we do at Diffusion, and the design of the new Modular Highline range is no exception. Its unique modular design, compact dimensions and advanced, energy-efficient components ensure its reliability and high performance, making it ideal for multiple commercial applications.  We are proud to have won the prestigious CIBSE Building Performance Award for Product Innovation for thermal comfort in 2024, and to confirm that we will be using the same innovative and energy-efficient components to introduce more products to the range.

Every detail of the modular design was considered with great care and emphasis on sustainability.  The result is a new range of high-performing, modular units that are easy to specify, install and maintain.
