What we do
Keeping people safe has been at the forefront of our mind at Castell since our very beginning and is the essence of everything we believe and do.
From power generation & distribution, heavy plant works to loading bays and many industries in between, we believe that everyone has the right to be safe at work.
Close collaboration with our customers has built our experience over 95 years, and with this knowledge we help you to reduce and manage your risks. This improves safety practices & culture, can offer efficiency gains and reduces costs associated with workplace accidents.
We provide a range of safety components working in synergy to build a solution of trapped key interlocking to suit virtually any application. This enforces the operator to follow a safe procedure or process every time, safeguarding your people and assets.

Who we help
Our range of products have been developed to provide our customers with interlocks of the highest quality and integrity, protecting personnel and assets in high risk operating environments.
Castell products are found in a vast range of sectors (energy, industry, manufacturing, transport) and applications (loading bay safety, machine guarding) around the globe.
We help diverse stakeholders, from health and safety, compliance, project, operations, logistics, procurement managers and engineers to directors, who seek cost-effective safety solutions to prevent accidents, keep people and machinery safe at work, and safeguard processes.
Castell’s approach to working with customers is deeply rooted in understanding the safety issues found in modern industrial environments. Recognising how safety impacts operations is an important step to designing components that deliver fast safe access ensuring that efficiency is maintained and output rates are secured.
Our product range includes mechanical interlocks, motor sensing interlocks, valve interlocks, time delay key release units, key exchange boxes and access interlocks. The proper application of our products ensures that a process is followed and cannot be circumvented or short cut.
What our customers say
With a wide range of different applications, we very often see a challenge with either access or isolation control. To these needs we have found the best solution with Castell trapped key solutions.
Allan Hansen, Product Manager, OEM Automatic Klitsø, Denmark
Working in collaboration with Castell and two world leading automation companies on a solution for high-voltage switchgear systems on a nuclear power plant in China, we implemented a safety interlocking concept with Castell products achieving the greatest possible plant & personnel protection.
Markus Schönbächler, Project Engineer, MATTLE Industrie-Produkte AG, Switzerland
In our experience, when the alignment of a door or hatch is not stable, it is better not to use normal safety switches for isolation or protected units. For these types of applications we usually would recommend to our customers systems using a separate isolation unit and AI/AIE locks for the misaligned doors or hatches.
Tony Tarr, OEM Automatic, Finland
We use Castell access locks on concrete-mixers where there are heavy duty ids, doors and hatches. All of these areas are exposed to both wet and dry concrete. The hinges on these doors are usually worn out fast and makes the door wobbly, but this is not a problem for Castell access locks. We also have instances where the locks have been completely encased in concrete. After they are chipped and lubricated, the locks still work fine. This shows us, how tough these access locks are.

Ultimately, Salvo offered us a robust, cost-effective solution that our workforce had faith in. Our warehouse staff are now more comfortable in their working environment and our drivers have taken to the system quite readily.
Mark Ford, Assistant General Manager, Wincanton
It’s a simple, user-friendly process that fits everything. Traditional vehicle-restraint technologies were a non-starter because of the varying specifications of our twelve-year-old fleet – not to mention the cost of fitting out 90 bays at £10,000 per bay!
Iain McManus, Sustainability Manager, Walkers
With the timber industry prevailing in Sweden, Castell systems for sawmill applications are of upmost importance. Machines such as band saws which have a danger of moving blades require a safe electrical isolation to then gain full body access. Castell systems ensure that access can only be gained once the hazardous area is safe and with the personnel key on access interlocks the system provides extra safety to the personnel working on the band saw.
