Introduction

Introduction

Congratulations on purchasing your VARIBOX FC

The VARIBOX FC is a unique IBC developed for safe packing and transport of dangerous materials. It has a capacity of 800 or 1,000 litres and has been tested extensively on durability and intensive usage. The VARIBOX FC features double containment: The inner bottle is surrounded by a second containment box.

Product description

The UN approved VARIBOX® Full Containment is double walled. This ensures that your products stay safely inside. There’s no need to use additional spill pallets. Certified by the German DIBt.

The VARIBOX FC is shaped like a bathtub. Extractor tubes with leak free couplers for top discharge are available as an option. With the extractor tube in a sink this minimizes residues and waste.

The ergonomic positions of the fill opening and optional extractor tube improve safe handling throughout the supply chain.

Multiple label fields are available for your obligatory product information on all sides of the VARIBOX FC. These label fields are recessed to protect your product labels and keep them readable for your customer.

The VARIBOX FC is discharged from the top. Users safely connect to a leak-free extractor. No need to open caps or closures, no risk of contact with chemicals. The VARIBOX® creates a closed system.

The automatic venting avoids errors by your customers when discharging your product. A pressure release system is available for products that build up pressure.

The pallet has three runners for a smooth transport on roller conveyors. The rounded pallet runners are designed to withstand the impact imposed by hand pallet trucks.

All main parts of the VARIBOX FC are made of Polyethylene; the pallet is manufactured from recycled material. These parts are made by the rotational moulding process; this production process ensures a tension free product with high mechanical impact strength.

Limitation on shelf life and warranty

This document outlines the terms and conditions of the limited warranty and shelf life for our VARIBOX components. Please read this document carefully as it explains the scope and limitations of the warranty.

Safety and liability

Warranty and Shelf Life

We acknowledge that providing an unconditional shelf life and warranty for our VARIBOX components is challenging due to numerous factors that are beyond our control. These factors include but are not limited to the handling, transportation, filling, storage, and usage of the VARIBOX. Additionally, the acceptance criteria and perceptions manufacturers, fillers, and users can vary significantly. Furthermore, the nature of the filling product can also substantially impact the VARIBOX components lifespan.

Shelf life of VARIBOX components

  • VARIBOX Safeline Performance extractor tubes
  • VARIBOX Safeline Precision extractor tubes
  • VARIBOX Safeline Food extractor tubes
  • VARIBOX Safeline counter couplers
  • NS4 extractor tube
  • CDS extractor tubes
  • Overpressure vents
  • VARIBOX Screwcaps
  • Level sensors
  • Counter connectors

Provided that our products are transported, stored, applied, and handled responsibly, we estimate that they should remain suitable for their intended use for at least the following periods:

Shelf life of VARIBOX components before application is up to 24 months.

Shelf life of VARIBOX components fitted in/on a VARIBOX/in-use is up to 12 months.

Shelf life before application assumes that the components are stored in their original package in a dry place without extreme temperature variations. In practice, the shelf life may exceed the indicated durations. However, tropical (humid) storage conditions may result in a shorter shelf life of the components.

The shelf life of VARIBOX components depends on product selection. Under typical conditions, it can exceed 12 months. Nonetheless, improper handling, exposure to highly corrosive substances, or harsh environments like tropical conditions can significantly shorten the shelf life.

Damage will occur due to wear and tear, including chemical degradation, improper use, abuse, alterations to the components, or unauthorized repairs.

*: overpressure relief vent is required or advised **: We do not recommend the use of non-conductive plastic packaging for products with a flash point of 60°C or lower ***: Only when specified in UN approval

CAUTION: The VARIBOX has been developed and tested for intensive use. Each VARIBOX can be reused multiple times for similar liquids. Do not reuse any PE packaging for products with an oxidizing effect on PE causing molecular degradation, after it has been used for products that cause PE to swell (like hydrocarbons) or that have a stress-cracking effect on PE (surface-active wetting agents such as alcohols, soaps, surfactants).

CAUTION: Chemicals at temperatures over 30°C can cause faster degradation of materials. Make sure not to use the VARIBOX with chemicals at higher temperatures.

CAUTION FOR STORING NITRIC ACID: The storage temperature of nitric acid in a polyethylene IBC is a factor that greatly influences the container's service life. We recommend not exceeding 20°C when storing nitric acid (≥50%) in order to preserve the VARIBOX's service life.

Venting

Venting

Choose the correct venting

The VARIBOX FC has as standard a vacuum vent and an overpressure relief vent, levelling under and over pressure during use.

The VARIBOX FC can also be equipped without an overpressure relief vent. This version can be used when vapor that may be released leads to danger on account of, for example, its toxicity, flammability, or the quantity of gas released. This is described in ADR 4.1.1.8.

Some products can build up pressure. The ADR requires an overpressure relief for specific substances like Hypochlorite solutions and Hydrogen peroxides. This is described in ADR 4.1.4.2, IBC02, B5.

IBCs should be fitted with a device to allow for venting during transport for amongst others:

  • UN1791 hypochlorite solution (chlorine bleach, sodium hypochlorite)
  • UN2014 hydrogen peroxide, 20-60% solution
  • UN2984 hydrogen peroxide, 8-20% solution
  • UN3109 organic peroxide type F, peracetic acid 15%
  • UN3149 hydrogen peroxide and peracetic acid, mixture, not more than 5% peracetic acid

CAUTION: Overpressure may develop in the VARIBOX FC due to warming of the air or the emission of gas from the contents, because of a temperature rise or other cause. To avoid warming of the air, the VARIBOX FC needs to be shielded from direct sunlight during outside storage.

The VARIBOX FC may be equipped with an overpressure relief vent to avoid a pressure build-up.

If you use the VARIBOX FC without overpressure relief vent, overpressure may be visible by bulging up of the top of the VARIBOX.

When this overpressure is visible, remove the overpressure before you connect or open the VARIBOX. You can do so by loosening the lid by 30°. This will avoid a sudden relief of pressure and possible spill of content. Make sure to wear appropriate personal protective equipment.

When overpressure builds up, the extractor tube and/or empty level sensor may lift out of its designated recess. If this occurs, the extractor tube and/or empty level sensor may float and will therefore not function as intended anymore. After the overpressure has been released and the box is emptied, the tube and/or sensor may have to be repositioned in the designated recess.

Outer container & containment

Outer container

Using the full containment outer container

CAUTION: It’s prohibited to add a connection or hole to the outer container.

This VARIBOX FC (Full Containment) comes with a fully closed outer container. The volume of this outer container is the volume of the inner container +10%, in line with typical regulations.

Use of the outer container

  • Users of the VARIBOX FC need to be trained before using the product
  • The product needs to be placed on an even and stable floor
  • When the product is placed outside, it needs to be protected from wind and shielded against direct sunlight
  • Protect the product from collisions with vehicles
  • Do not apply forces to the outer container
  • Placement has to be in line with fire regulations
  • Check the spill container regularly for leakage, by checking the dipstick in the top cover (see picture)
Outer container & containment
  • Max. application temperature: 30°C
  • When detecting fluid between inner bottle and outer container, remove fluid immediately
  • In earthquake zones 1 to 3 in accordance with DIN 41495, the product must be adequately secured in their position so that no concentrated individual loads act on the container combinations in the event of an earthquake
  • Products which are damaged, so they cannot function any longer cannot be used
  • Repairing the product can only be done by authorized personnel
  • The outer container needs to be inspected and (if necessary) cleaned on a regular basis (i.e. annually or sooner if necessary); this inspection needs to be documented
  • All legal requirements need to be met on local, national and international level
Handling & transport

Handling

Closure tools

The VARIBOX FC needs to be closed during handling. Appropriate closure tools are to be used and closure torques are to be respected. Examples of closure tools are shown below.

Handling & transport

Transport of the VARIBOX FC

Follow local, national and international regulations for securing the VARIBOX FC for transport.

During transport, the UN marking is visible at the front of the outer container. The date of manufacture of the inner container is visible below the UN marking at the front of the outer container.

Filling & closing

Filling

Preparing for filling

The inside of the VARIBOX FC has been cleaned to remove polyethylene chips that result from production. Afterwards, polyethylene residues may still be found in the product. We therefore recommend that you always clean and, if necessary, disinfect in accordance with your internal regulations and / or that of competent authorities before using new products.

Filling the VARIBOX FC

Use the 150 mm opening to fill the VARIBOX FC. The maximum filling temperature is 30°C.

CAUTION: Ensure that the optional extractor tube is vented during filling. As a result, air can escape from the extractor tube and possible floating of the suction pipe is prevented. Open the extractor tube by connecting it with the corresponding connector. Make sure that potentially dangerous gases are sucked away.

Closing the VARIBOX FC

Verify the correct placement of the vacuum vent. Inspect the optional membrane filter for de- aeration; this should be dry and clean to prevent pressure build-up.

CAUTION: Membrane filters for de-aeration are developed for one-time use. When contaminated or when wet, the filters may block and lose their capacity to prevent pressure build-up. Replace the membrane filter after use to secure venting.

Use the original closures to close the VARIBOX FC. Respect the following closure torques:

  • Red or green or blue fill cap: 80 Nm
  • Yellow housing in fill cap: 14 Nm
  • White housing in fill cap: 14 Nm
  • Extractor tubes Safeline: 14 Nm
  • Extractor tubes AS: 20 Nm
  • Extractor tubes Safeline: 14 Nm

CAUTION: Always put a cap on the vent to prevent blocking or entering of (rain-) water. Do not remove the threaded vent housing from the screw lid as the membrane filter will release from the housing and drop into the container.

Sealing

The 150 mm screw lid can be sealed. A tamper evidence cable can be fed through holes in the lid and the hole in the top cover of the VARIBOX FC.

The extractor tube can be sealed with a corresponding cap; visit our VARIBOX webshop.

For other tubes, consult the extractor tube supplier for advice.

Connecting

Emptying using a NS4 extractor tube

The VARIBOX FC is available with NS4 extractor tube in an EPDM and Viton version for spill-free connecting to a pump as well as for connecting an optional return line. The NS4 extractor tubes automatically close after disconnection. Tube and housing are made of Polyethylene, connectors are made of Polypropylene and springs are made of Hastelloy. The extractor tube has an inner tube diameter of 6 mm and is equipped with a non-return valve at the bottom. The capacity of this extractor tube is 50 litre/hour. After emptying about 0,1 litre remains in the VARIBOX FC. In the extractor tube itself about 0,05 litre will remain. These indications are based on water and will vary upon condition and type of chemical.

CAUTION: The non-return valve blocks the return stream but cannot guarantee a full sealing.

CAUTION: If there was 0.2 bar or more pressure in the VARIBOX always check if the NS4 system still reaches the lowest point in the VARIBOX.

The connections are small parts. These parts can break off. Limit the forces on them, e.g. when coupling or the weight of a hose.

The connection’s O-ring (Out: Extractor connection and Insert) is a part that can wear out during coupling. Check this O-ring and replace it if necessary with the same O-ring of the correct material (EPDM or Viton) and the correct size (8x1.8).

NS4 is manufactured from Polyethylene, PP and other materials. Verify the chemical compatibility of your product with these materials or ask our Customer Service.

Emptying using AS QC2 dip tube system

The AS QC2 dip tube system is supplied by AS Strömungstechnik GmbH, an external partner and specialist manufacturer of dispensing and filling systems for liquid chemicals. VARIBOX® fits the AS QC2 dip tube into the container prior to delivery. Flow rate is 25–50 l/min. For all technical questions, coding, dispense heads, tooling and transport approvals relating to the QC2 system, please contact AS Strömungstechnik GmbH directly.

Connection procedure

  1. Delivery – the AS QC2 dip tube is pre-installed into the container by VARIBOX®. There is no contact with the liquid when connecting.

  2. Connection – align the dispense head with the dip tube coding and connect: click into place, screw tight. The pin-hole coding only allows matching coded components to connect.

  3. Dispensing – dispensing takes place in a closed circuit; ventilation runs via the check valve, particle filter or flexible tubing integrated in the dispense head. The second container opening can remain sealed.

  4. Disconnection – the shut-off valve(s) in the dispense head close on disconnection, preventing spillage.

Coding

The dip tube and dispense head can be matched using a pin-hole coding system, so that only the correct components for a given chemical can be connected. The dispense head and pins are supplied by AS, not by VARIBOX®. Assignment and management of the coding is the responsibility of the customer. AS provides a dedicated coding tool for this on request — contact AS directly.

RFID / traceability

Return it: recycling

Return it

Return it is a take-back programme for used VARIBOX intermediate bulk containers (IBCs). Containers returned through the programme are recycled: the material is reprocessed and reused in the production of new VARIBOX IBCs.

How it works

  1. Return – register old VARIBOX IBCs and deliver them to VARIBOX.

  2. Recycling – the returned containers are ground into shreds and reprocessed with additives into plastic pellets, which are used in the production of new VARIBOX IBCs.

  3. Certificate – a certificate of participation in VARIBOX Return it is issued, confirming that the returned containers have been recycled responsibly.

Register your containers

Containers can be registered for the VARIBOX Return it programme via the dedicated Return it page.
