VARIBOX FC 1000, the Double Walled IBC for Hazardous Chemicals

When transporting, storing or handling dangerous liquids, safety must be engineered into the packaging itself. The VARIBOX® FC 1000 is a UN-certified double walled IBC developed specifically as a high-performance hazardous chemical IBC. With integrated 110% spill containment, closed-system top discharge and full ADR compliance, it sets a new safety benchmark for chemical logistics across Europe and international markets.

What Makes the VARIBOX FC 1000 Different?

The VARIBOX FC 1000 is a full containment IBC with a true double-wall construction:

• Inner container (primary containment)

• Fully closed outer container (secondary containment)

• 110% integrated spill containment capacity

Unlike standard composite IBCs that require external drip trays, this double walled IBC integrates containment into the design itself.

Result:

• No additional spill pallets required

• No external drip facilities

• Easier compliance with European storage regulations

• Safer installation on-site

The system holds DIBt approval (abZ Z-40.21-534) for spill containment in Germany — a critical certification for stationary storage.

UN Certified & ADR Compliant IBC

The VARIBOX FC 1000 is officially UN approved:

UN 31HH1/Y/–/NL/TCPI-PROMENS3-140531/3750/2028**

Approved for:

• Packing Groups II and III

• ADR (road transport)

• RID (rail)

• IMDG (sea transport)

As an ADR compliant IBC, it fulfils the strict testing requirements under ADR Chapter 6.5 for hazardous goods packaging. For chemical distributors and industrial producers operating across borders, regulatory certainty is essential. The VARIBOX FC 1000 delivers that certainty.

Closed System Hazardous Chemical IBC

A key differentiator is the top discharge closed system. Instead of a bottom valve, the VARIBOX FC 1000 uses an internal extractor tube system:

• No bottom tap

• No manual opening during discharge

• No direct chemical contact

• No uncontrolled vapours when connected correctly

Safeline and NS4 systems automatically close after disconnection, maintaining a closed loop. For operators handling corrosive acids, oxidisers or alkaline substances, this dramatically reduces exposure risk.

Extremely Low Chemical Residue

The inner container is shaped with a sloped bottom and top for optimal drainage.

After emptying:

• ±0.1 litre remains in the tank

• ±0.4 litre remains in the extractor tube (Safeline Performance)

• Total residue < 0.5 litre

Benefits:

• Reduced chemical waste

• Safer return transport

• Lower cleaning costs

• Improved sustainability metrics

For a hazardous chemical IBC, low residue equals safer logistics.

Chemical Compatibility – Commonly Used Industrial Chemicals

The VARIBOX FC 1000 is widely used for storage and transport of many frequently handled industrial chemicals, including:

Acids

• Acetic acid

• Nitric acid (up to 62%)

• Hydrochloric acid

• Hydrofluoric acid (≤60%)

• Phosphoric acid

• Sulfuric acid

• Peracetic acid (≤15%)

Alkaline Substances

• Sodium hydroxide

• Potassium hydroxide

• Sodium hypochlorite

• Sodium chlorite

Oxidising & Reactive Chemicals

• Hydrogen peroxide (≤60%)

• Sopuroxid 15%

• Ferric chloride

Other Industrial Liquids

• n-Butyl acetate

• White spirit

• Wetting solutions

• Citric acid

• Ammonia (≤20%)

Correct gasket selection (EPDM or Viton) ensures long-term chemical resistance.

For chemical distributors, this makes the VARIBOX FC 1000 a highly versatile industrial chemical IBC.

Markets That Use the VARIBOX FC 1000

The VARIBOX FC 1000 serves multiple markets where safe chemical handling is critical.

Chemical Distribution

Chemical distributors require:

• ADR compliant IBCs

• Multi-trip durability

• Safe cross-border transport

• Reduced packaging waste

The double walled design and integrated containment simplify regulatory compliance while reducing operational risk.

Water Treatment

Used for:

• Ferric chloride

• Sodium hypochlorite

• Potassium hydroxide

• Polyaluminium chloride

In water treatment facilities, preventing leakage is crucial. The integrated spill containment and closed discharge system enhance environmental protection.

Cleaning & Detergents

Manufacturers of cleaning agents rely on:

• Citric acid

• Peracetic acid

• Sodium hydroxide

• Surfactants

The closed system reduces operator exposure during dosing and transfer.

Industrial Manufacturing

Used in:

• Process chemicals

• Intermediate products

• Surface treatment chemicals

• Metal processing fluids

The durable design withstands high-frequency industrial use.

Venting & Pressure Safety

Standard configuration includes:

• Vacuum relief vent (120 l/min)

• Overpressure vent (80 l/h at ΔP 12 mbar)

ADR requires venting for substances such as hypochlorite and hydrogen peroxide.

The integrated system prevents pressure build-up during storage and transport.
