Safety that keeps the flow running in automated cold storage

In highly automated warehouse environments, systems are expected to run continuously, and even minor downtime can have significant consequences.

In Kuurne, Belgium, Coldo operates a highly automated freezer warehouse reaching nearly fifty metres in height. For Ceratec, responsible for delivering the automation solution, the challenge was clear: how to ensure safety, accessibility and maintenance without interrupting the flow.

A complex environment with no room for downtime

In environments like Coldo, where automation runs continuously, safety must be built into the operation without interrupting it. In cold storage environments, even short interruptions can increase energy demand as the system works to restore stable operating temperatures. This becomes particularly challenging in areas such as lifts and racking systems, where maintenance needs to be carried out without shutting down the entire installation.

This requires a system designed to:

• Ensure safe separation of zones
• Enable continuous operation in parallel
• Provide high accessibility for service and maintenance

The biggest challenge is combining safety with user-friendliness

A safety solution adapted to continuous operation

To meet these requirements, Ceratec worked closely with Axelent Benelux throughout the engineering phase. The ability to deliver components in structured packages for each area of the installation simplified both installation and integration.

To support safe and continuous operation, Axelent contributed with:

• Modular safety solutions adapted to different zones
• Fast feedback on design proposals
• Technical support for specific requirements

This collaborative approach made it possible to adapt the safety solution to different parts of the installation while maintaining accessibility and operational continuity.

Maintaining flow during maintenance and service

The result is a safety solution that supports both safety and uninterrupted operation.

By enabling maintenance work in isolated sections, the system can continue running without unnecessary interruptions, a critical factor in operations running around the clock.

At the same time, usability and accessibility remain high, ensuring that operators can work safely and efficiently within a high-demand environment.

“It is important that we split everything up so the rest of the installation can continue operating while maintenance is carried out elsewhere,” says Maarten Vanoverberghe.

A partnership built on responsiveness and trust

With a long-standing collaboration, Ceratec highlights the value of responsiveness and technical support.

Thanks to the collaboration with Axelent, everything is resolved quickly and we receive prompt feedback

In complex automation projects, having a partner who understands both safety requirements and operational reality makes a measurable difference in maintaining safe and continuous operations.
