Creating an optimal indoor environment is essential for productivity and well-being in public buildings and offices. At Biddle, we recognise the importance of providing comfortable and energy-efficient HVAC solutions tailored to the unique needs of these spaces.

Our expertise lies in delivering cutting-edge technologies that ensure superior climate control, enhance air quality, and promote occupant comfort.

Comfort Circle Cassette for Enhanced Comfort and Efficiency

Elevate the comfort level of your buildings with the remarkable features of the Biddle Comfort Circle Cassette unit. Engineered for heating, cooling, and ventilation, this versatile system offers unparalleled performance and aesthetics. Whether you need to create an inviting atmosphere in an office, reception areas, conference rooms, open workspaces, or public spaces, the Comfort Circle delivers exceptional results.

The Comfort Circle Cassette unit boasts circular discharge technology. Through its round grille, air intake and discharge occur seamlessly, ensuring a balanced and uniform airflow throughout the space. Unlike traditional square grilles, the circular discharge pattern minimises air velocity, resulting in improved air distribution and enhanced comfort for employees, visitors, and occupants.
