VARIBOX CC 250 – ADR Compliant Double-Walled IBC for Safe Chemical Storage

The VARIBOX CC 250 is a UN-certified, ADR-compliant double-walled 250-litre IBC, specifically developed for the safe storage and transport of hazardous liquids. Where traditional IBCs or drums rely on separate spill pallets and open handling procedures, the VARIBOX CC 250 provides an integrated containment solution that combines safety, regulatory compliance, and operational efficiency in one robust system. This is not a standard IBC. This is compact containment engineered to meet the highest European standards.

What makes the VARIBOX CC 250 unique?

1. Double-walled safety with 110% integrated spill containment

The VARIBOX CC 250 features a fully closed outer container with a containment capacity of at least 110% of the inner container volume. This means:

• No separate spill pallets required

• No secondary containment constructions underneath the IBC

• Immediate compliance with secondary containment requirements

• Maximum protection in case of leakage or damage to the inner container

For companies handling hazardous substances, secondary containment is not an option — it is a requirement. The VARIBOX integrates this requirement directly into its design.

This minimizes:

• Soil contamination

• Workplace risks

• Environmental damage

• Operational downtime in the event of incidents

2. The most compact double-walled IBC on the market

With a nominal capacity of 250 litres and a footprint of approximately 600 x 800 mm, the VARIBOX CC 250 is designed for use in confined spaces.

Key technical data:

• Nominal capacity: 250 litres

• Gross capacity: 275 litres

• Dimensions: approx. 600 x 800 x 1200 mm

• Weight: approx. 38 kg

• Stacking load: 522 kg

• Up to 132 units per truck

Thanks to its compact design, the IBC easily passes through standard industrial doorways and fits into technical areas where traditional IBCs are too large.

ADR Compliant and UN Certified

When working with hazardous liquids, regulatory compliance is essential.

The VARIBOX CC 250 is fully certified according to international transport standards:

• UN certification: 31HH1/Y

• Suitable for Packing Groups II and III

• ADR (road transport)

• RID (rail transport)

• IMDG (sea transport)

• DIBt approval for stationary storage in Germany

UN certification number: UN 31HH1/Y/–/NL/TCPI-PROMENS3-200518/950/522

What does 31HH1/Y mean?

• 31HH1 = plastic IBC for liquids

• Y = suitable for Packing Groups II and III

• Tested according to ADR Chapter 6.5

This confirms that the container complies with requirements for:

• Drop tests

• Stacking tests

• Pressure tests

• Leak tightness

Additionally, ADR requires periodic inspection and testing (maximum every 2.5 years) to ensure structural safety throughout the product’s service life.

Closed system: less risk, more control

An important safety aspect of chemical storage is minimizing direct contact.

The VARIBOX CC 250 supports various extractor systems that enable direct pump connection, creating a closed system during emptying.

Advantages:

• No open pouring

• No splash risk

• No vapour exposure

• Reduced risk of incorrect connections

• Automatic closure upon disconnection

This lowers the risk of workplace accidents and improves process reliability.

Chemical compatibility – Standard approved substances

The VARIBOX CC 250 is used worldwide for a broad range of chemicals.

A complete overview is available via:
https://varibox-ibc.com/chemicals-in-the-varibox/

Common approved substances include:

• Acetic acid

• Ammonia (<20%)

• Citric acid

• Ethylene glycol

• Ferric chloride

• Formaldehyde

• Formic acid

• Hydrochloric acid

• Hydrofluoric acid (≤60%)

• Hydrogen peroxide (≤60%)

• Nitric acid (≤55%, limited to 62%)

• Peracetic acid (≤15%)

• Phosphoric acid

• Polyaluminium chloride

• Potassium hydroxide

• Sodium hydroxide

• Sodium hypochlorite

• Sodium chlorite

• Sodium silicate solutions

The VARIBOX is available with different sealing materials (EPDM or Viton), depending on chemical resistance requirements. When using mixtures or non-standard concentrations, a compatibility assessment based on the Safety Data Sheet (SDS) is recommended.

Advanced pressure and venting system

Chemical reactions or temperature fluctuations may cause pressure build-up.

The VARIBOX CC 250 is equipped as standard with:

• Vacuum relief valve (120 l/min)

• Overpressure relief valve (80 l/hour at ΔP 12 mbar)

For substances such as sodium hypochlorite and hydrogen peroxide, pressure relief is mandatory according to ADR 4.1.4.2.

This prevents:

• Container deformation

• Uncontrolled pressure release

• Safety incidents during opening

Correct vent configuration is essential for safe storage.

Maintenance, inspection and service life

The VARIBOX CC 250 is designed as a multi-trip IBC with a long operational service life.

Key aspects:

• Designed service life: up to 10 years

• Inner container replacement required after 5 years (ADR compliance)

• Periodic inspection according to ADR (max. every 2.5 years)

• Routine maintenance according to UN guidelines

The sloped bottom minimizes residual volume (approx. 0.1 litre) and facilitates cleaning.

Maximum filling temperature: 30°C
Maximum cleaning temperature: 60°C

With proper maintenance, the container remains fully compliant throughout its lifecycle.

Risk analysis: Traditional storage vs. VARIBOX

Traditional drums or single-walled IBCs:

• Require separate spill pallets

• Involve more manual handling

• Higher risk of spills

• Open pouring operations

• Increased exposure risk

VARIBOX CC 250:

• Integrated spill containment

• Closed system

• Reduced physical strain

• Compact design

• Fully ADR compliant

For companies that prioritise safety and compliance, this represents a structural improvement in storage strategy.

Markets and applications

The VARIBOX CC 250 is used across various industries.

Key sectors include:

• Chemical distribution

• Water and wastewater treatment

• Industrial production

• Cleaning and hygiene products

• Agricultural applications

• Technical installations

Its versatility makes this IBC suitable for both fixed installations and logistics chains.

The new standard in compact chemical storage

The VARIBOX CC 250 combines:

• Double-walled safety

• Integrated spill containment

• UN and ADR compliance

• Compact design

• Long service life

• Industrial robustness

For organisations handling hazardous liquids, this system delivers:

• Reduced risk

• Improved regulatory compliance

• Lower operational complexity

• Greater sustainability

The VARIBOX CC 250 is therefore not just packaging — it is a structural safety solution for professional chemical storage and transport.
