Conductive Flexible Containers

Type C Flexible Container

Specifically designed to work in flammable atmospheres (including those containing hydrocarbon vapors).

These containers are made of polypropylene raffia with conductive fibers. The grid created by intertwined threads conducts the static electricity generated.

This type of Flexible Containers requires an earthing conductor.



R < 108 Ohmios.

Type C Flexible Container

For CONDUSAC® to work properly, the conductive loop must be correctly earthed with a suitable clip. Nevertheless, Flexible Containers usually include redundant earthing systems, such as the handles touching the metal chain and the hoisting device. Not earthing them may lead to high-current discharges.

The material used has an resistance of under 108 ohms, as required by the IEC 61340-4-4 Standard (Electrostatics Part 4-4: Standard test methods for specific applications – Electrostatic classification of flexible intermediate bulk containers (FIBC)).

icon-danger-8In July of 2003, the 1999/92/EC directive also known as ATEX- 137 came into force and was incorporated to Spanish law by means of the ROYAL DECREE 681/2003, of June 12, regarding the health and safety protection of workers exposed to the risks of explosive atmospheres in the workplace.
Explosive atmospheres are generated in the productive processes of many different sectors. An explosion-related risk-assessment study is required in this kind of industry.
Electrostatics is one of the most difficult ignition sources to control and is responsible for a large number of accidents. During production processes, static electricity can be produced during loading, unloading or due to friction with the container.
To avoid these risks, CLIMESA  has designed different types of flexible containers to optimize the passive safety level and the financial resources required.
