Düperthal - Certified system solutions for secure storage of hazardous substances

Process analysis

Your processes should run optimally - in every respect. Our experts take a closer look at safety-relevant and profitability aspects. You are guaranteed the greatest possible flexibility in implementation. Because we have the right solution for every situation.

Process analysis
From process analysis to concept
Our experts will work together with you on-site to collect extensive data in an as-is analysis. Based on this information and your requirements, a target state is defined in a functional specification document.
System solutions
Modular and tested system solutions
We use the full range of DÜPERTHAL’s standard technologies and supplement these with modular and type-tested systems individually tailored to your requirements.

You don't just get a technically perfect system from us – we also make sure that the effort required on your part is minimised. We deliver our products directly to your site and take care of the implementation. Full service is our principle.

Shipment and delivery
Safety for us starts with the delivery of the product. The specialist carrier appointed by us works according to a detailed checklist and therefore ensures that our products are professionally transported to and installed in their final place of use - delivery just-in-time and just-in-place.
Project support
On-site project support
The professional handling of complex projects requires more than just delivery of safety storage cabinets. DÜPERTHAL therefore provides comprehensive support for your national and international projects with planning, delivery service, construction site support and training of lab managers and users.
On-site project support
Our team of specialists ensures a smooth, optimised assembly process on-site. After a complete installation of all components, the commissioning and joint final acceptance are carried out with you.

We strive all the time to optimise your process flows sustainably. This means that we attach great importance to documentation and training. We also use cutting-edge technology for evaluation. This allows us to integrate our products into your existing structures as seamlessly as possible.

Product variety
Product diversity, certified system solutions
Our diverse product range offers solutions tailored specifically to your requirements. In addition to maximum safety, they offer the highest levels of effectiveness and efficiency – including in situations where there is no risk of fire.
Detailed operating instructions are supplied with each product, especially for complex projects. The manual supplied includes the CE certificate of conformity and the type certificate for the patented system solutions tested by independent third parties.
Training and risk assessment
To reassure you that our components can be used in a technically correct manner and can be operated without any risk, we will be happy to train your personnel on-site. The points covered can be included in your risk assessment.
With our web-enabled Cabi2Net, all relevant operating parameters of the safety storage cabinets can be continuously monitored and evaluated. Information can be queried with ease from a mobile phone, tablet or PC. This also safeguards your processes and helps you make your internal value chain even more efficient.

To ensure the functionality and safety of your system solution in the long term, we recommend an annual inspection. Our service agreement guarantees you maintenance and spare parts long after installation and commissioning.

Occupational safety and health (OSHA/EU-OSHA)
Protecting employees and the environment is the highest priority when handling hazardous substances. Therefore, DÜPERTHAL safety storage cabinets guarantee compliance with the requirements of the Occupational Safety and Health Administration (OSHA and EU-OSHA). We will clarify all relevant topics and train you in the safe handling of our products.
Permanent service contract
Permanent service agreement with regular maintenance and service
Highly complex processes rely on robust structures. With our service agreement, we can ensure even greater safeguarding of our reliable system solutions in your interest. The annual maintenance also extends the manufacturer's guarantee. A dual benefit for you - in terms of safety and profitability.


Passive storage is the storage of flammable liquids in containers that are securely sealed and that are not filled or disposed of in the store or opened for any other purposes.

Active storage is the storage of flammable liquids in non-stationary vessels that are used at their storage location as stationary removal or collection containers or opened for other purposes.

If filling or transfer is carried out on the safety storage cabinet (= active storage), operation without an industrial exhaust system is not permissible. For storage of sealed containers (passive storage), operation without an industrial exhaust system is permitted provided the following requirements for the containers to be stored are satisfied:

    The containers stored must be sealed tightly.
    They must be inspected regularly for leaks.
    Opening of the containers must not be possible.

This must be documented in the explosion protection document, and the resulting ex-zones around the safety storage cabinet must be maintained:

  • If a safety storage cabinet does not have industrial ventilation, the interior may pose an explosion hazard and is thus classified as ex-zone 2. The area around the safety storage cabinet is not an ex-zone.
  • However, if any of the aforementioned conditions regarding containers is not satisfied, the interior of the safety storage cabinet is classified as ex-zone 1 and the surrounding area to a distance of at least 2.5 m from the cabinet and up to a height of at least 0.5 m above the floor is classified as a potentially explosive area, i.e. ex-zone 2.
  • In working spaces with industrial ventilation with at least a five-fold air exchange per hour, the potentially explosive area of zone 2 can be reduced to 1 m in front of the safety storage cabinet, 0.5 m on either side of the cabinet and a height of 0.3 m above the floor.

For passive storage, operation with an industrial exhaust system with a minimum of 10-fold continuous air exchange per hour is therefore advisable. In this case, no ex-zones are assigned to the cabinet.

The air exchange rate is specified by the operator as part of the risk assessment for the workplace. Generally accepted values can be used as the basis for determining the rate:

For passive storage of flammable liquids, at least a 10-fold air exchange per hour is recommended to avoid the formation of an ex-zone. A higher rate of air exchange may be necessary to reduce odours.

For active storage of flammable liquids, the safety storage cabinet must be operated with an air exchange rate of at least 21 m³/h and the ventilation function must be monitored.

Flammable gases should be stored with at least a 10-fold air exchange per hour, and toxic gases with at least a 120-fold air exchange per hour.

Safety storage cabinets without industrial ventilation and safety storage cabinets for active storage must be earthed by equipotential bonding to avoid ignition hazards.
