Security cabinet

What are the filtration and ventilation options for a security cabinet?

For Voussert security cabinets, the available filtration and ventilation options are as follows:
• Filtration unit : A filtration module is offered with an ERLAB filter included.
• Mechanical ventilation unit : A motorized ventilation system is available, offering a flow rate of 75 m³/hour.
In addition to these options, the cabinet comes standard with 80 mm diameter ventilation grilles with a pre-installed roof connection. These grilles are equipped with an automatic shut-off device that activates in case of fire to ensure the structure remains airtight.

How do I install the filtration unit on the roof?

To install the filtration unit (optional with ERLAB filter) on the Voussert T30 IHL cabinet, you must use the connection points provided for this purpose on the structure:
• Connection point: The installation is done directly on the roof of the cabinet, where the ventilation outlets are located.
• Compatibility: The box must be connected to ventilation outlets which have a diameter of 80 mm (Ø 80 mm).
• Integrated safety: These ventilation outlets are already equipped with an automatic shut-off device that activates in case of fire to isolate the cabinet

What are the advantages of an ERLAB filter?

• Simplified integration: The ERLAB filter has the advantage of being directly included when purchasing the optional filtration box.
• Certified compatibility : This is an option specifically designed to work with the structure of the safety cabinet, ensuring compatibility with the equipment's ventilation system.
• Emission management : As mentioned in our conversation history, this type of filter is used to treat vapors and emissions from chemicals stored inside the cabinet.
In general, ERLAB filters are renowned for their high adsorption capacity and their filtration technology without external connection, which allows the cabinet to be installed in premises without a centralized extraction system while protecting the user against the inhalation of toxic fumes.

What are the advantages of high-pressure laminate (HPL)?

High-pressure laminate (HPL) is a material commonly used in laboratory and security environments for the following reasons:
• Chemical resistance : It offers excellent protection against splashes of solvents and corrosive products.
• Durability : It is an extremely robust material, resistant to shocks, scratches and daily wear and tear.
• Easy maintenance : Its non-porous surface facilitates decontamination and cleaning.
• Thermal stability : It retains its properties even in the event of temperature variations, which is consistent with the use of a fire safety cabinet.

How does the automatic closure using a thermal fuse work?

The operation of the automatic thermal fuse closure on a safety cabinet relies on passive thermal detection designed to isolate hazardous products in the event of a fire.
Here are the details of how it works:
• Activation threshold : The mechanism activates automatically when the temperature reaches or exceeds 50°C.
• Door action : In normal use, the cabinet has a hold-open system that allows the door to remain open for easier handling of the bottles. If the temperature rises to 50°C, the thermal fuse releases this hold, causing the door to close automatically and immediately to protect the contents from flames and external heat.
• Ventilation action : The safety system is not limited to the door. The ventilation openings (80 mm in diameter and connected to the roof) are also equipped with an automatic shut-off device. In the event of a fire, these ducts seal to prevent the spread of smoke and to stop external oxygen from fueling a potential fire inside the cabinet.
