When Sandfield Penstock Solutions set out to turn their Toggleblok valve into a complete, stand‑alone system, they needed an enclosure that would match the critical nature of their application. Their control panels are often installed outdoors, in the middle of fields or on busy industrial sites, and must continue to work flawlessly for years. Any weakness in the cabinet protecting the electronics would undermine the performance of the entire solution.

Introduction to Sandfield Penstock – A Fibox Technology Partner

Sandfield Penstock Solutions is a UK-based engineering company specialising in pollution containment and water control solutions for industrial and infrastructure environments. The company develops practical, stand-alone systems designed to prevent contaminated water from reaching the environment during spill, fire or flood events.

Fibox ARCA enclosures are now the standard housing for Sandfield Penstock Solutions’ control systems. Working closely with Fibox has given Sandfield Penstock Solutions a more robust, flexibe and dependable enclosure platform. Their experience shows how the right enclosure choice and close cooperation with the manufacturer can directly improve system quality and reliability.

Flexibility without unnecessary complexity

Another reason ARCA has become central to the Toggleblok system is the flexibility it offers without forcing Sandfield Penstock Solutions into bespoke fabrication. Many of their customers have specific requirements regarding how controls are presented. Some, for example, prefer not to have buttons and switches accessible on the outer door. With ARCA, Sandfield Penstock Solutions can use internal doors to mount controls behind a second protective layer, keeping the exterior clean and secure while still allowing authorised staff to operate the system easily.

For larger or more complex projects, Sandfield Penstock Solutions have also made use of floor‑mounted cabinets and modular extensions within the ARCA range. This gives them the ability to scale the enclosure to fit additional equipment or special configurations, while staying within a familiar product family. Working with standard accessories and modules keeps lead times under control and simplifies assembly, maintenance and future upgrades.

Benefits of the Fibox partnership

The close cooperation with Fibox has delivered clear commercial and practical benefits. Today, Sandfield Penstock Solutions order ARCA enclosures in planned quantities, benefiting from a more competitive pricing structure compared to single-unit purchases. This helps them manage costs as volumes increase and supports healthy margins for their own systems.

The direct relationship has also simplified engineering work. Instead of spending time navigating catalogues and product selectors, Sandfield Penstock Solutions can describe their requirements and constraints and work with Fibox to identify the most suitable enclosure. When a new project calls for a different configuration, they can quickly test ideas and access prototypes. This practical support frees their engineers to focus on what differentiates Toggleblok: system design, control logic and integration with customer sites.

A stable platform for dependable systems

Companies developing critical control systems for challenging environments face many of the same questions Sandfield Penstock Solutions did: how to protect electronics reliably, present a credible, high‑quality solution to customers, and avoid repeated redesigns as demand grows. Choosing the right enclosure platform, and working closely with the manufacturer, can make that journey significantly easier.
