What should you consider when installing a freezing tunnel in an industrial plant?

When a food company needs to quickly increase its freezing or defrosting capacity, response speed is everything.

However, rushed decisions can lead to technical errors, incompatibilities with the plant layout, or solutions that fail to scale with the business.

At Frío Modular, we share the key factors you should consider before installing a freezing tunnel in an industrial setting, especially if you're looking for a fast, safe and reliable solution.

1. Location and access logistics

Before choosing a model, it’s essential to evaluate where the tunnel will be installed:

• Is there enough space inside or outside the plant?

• Can delivery trucks or cranes access the area?

• Will the unit be installed at ground level, elevated, or attached to an existing structure?

At Frío Modular, we offer modular and portable solutions adaptable to any situation.

Our tunnels can be installed on platforms, connected directly to processing areas or placed outdoors without any civil works.

2. Operational integration with the plant

The tunnel must not operate in isolation—it needs to be seamlessly integrated into the workflow:

• Pallet or trolley entry and exit

• Manual or automatic doors

• Direct connection to cutting, packaging or cold storage rooms

Our equipment is designed to enable immediate functional integration without altering your usual operations.

3. Infrastructure: electricity, floor space and drainage

A common mistake is purchasing a tunnel without confirming the plant’s electrical capacity or ground conditions. That’s why we always:

• Analyze the available electrical power and recommend reinforcements if needed

• Assess floor leveling, anchor points and sanitary drainage

• Adapt the system to existing conditions—no complex construction required

Our goal is for you to have a fully installed and operational freezing tunnel within days, with no downtime.

4. Regulatory compliance and product requirements

Each product has different needs: freezing time, temperature, air flow, humidity. Every company must also comply with standards such as HACCP, ISO 22000 or CE marking.

Our tunnels are delivered with:

• Digital control systems for temperature, humidity and ventilation

• Certificates for electrical safety, sanitary compliance and CE certification

• Built-in protection elements: emergency lighting, trapped-person alarm, interior door release, safety axe, etc.

5. Scalability and future mobility

One of the most common mistakes with fixed tunnels is designing them for today’s production, without considering future changes.

Frío Modular tunnels allow you to:

• Expand capacity with additional units

• Relocate the tunnel to another plant or site

• Operate autonomously, even in locations with no prior infrastructure

Scalability and portability are essential for companies that grow quickly or face seasonal demand peaks.
