Overview

The Dudley Tri-Shell Auto is a heavy-duty automatic urinal cistern engineered for high-traffic commercial environments where durability and security are paramount. Featuring a unique sandwich foam moulding with a cellular core, the Tri-Shell body offers exceptional structural strength, making it the definitive anti-vandal solution for areas subject to potential misuse or harsh conditions.

Built with the same commitment to reliability found across the Dudley range, the Tri-Shell is designed for a maximum working life and ease of maintenance. The cistern is supplied with a Dudley Auto Syphon and petcock as standard, and is available in 4.5L, 9L, and 13.5L capacities to suit various installation requirements. While high-performance white is standard, a high-gloss black finish is also available as an option to suit specific aesthetic requirements.

To ensure full regulatory compliance and optimised water management, the Tri-Shell is designed to be paired with the Dudley Kinetic Infrared Urinal Flush Control. This combination provides specifiers with a complete, future-proof solution that balances heavy-duty engineering with smart functionality.
