The world's first conveyor belt closure

With the ECClos®-Flex-I, STÖBICH combines decades of expertise in textile fire protection with the field of application of conveyor system closures, in which STÖBICH ➥ pioneered more than 40 years ago.

The ECClos®-Flex-I is currently the 12th world innovation from STÖBICH: as the world's first conveyor system closure of textile construction with a European Technical Assessment (ETA).

What does this approval mean? Where is the ECClos®-Flex-I used, what advantages does it offer and how does it work in detail?

Components and function of the ECClos®-Flex-I

The ECClos®-Flex-I is a conveyor system closure consisting of a movable textile curtain and a fixed panel for enclosing the conveyor system in the closing area. In the event of a fire alarm, the fire protection closure closes the wall opening at a controlled speed by means of gravity-assisted Gravigen technology (self-firing, currentless). It thus segments buildings with intralogistics applications into fire compartments and prevents the uncontrolled spread of fire to adjacent areas. In its basic position, the ECClos®-Flex-I is open as planned and does not interfere with ongoing conveyor operations. It is equipped with an approved hold-open system with a certificate of usability from the building authorities, which releases the closure for closing when the alarm sounds.

Heat-insulating textile (sealing surface)

Several layers of different fabric types form a textile curtain that is only a few millimetres thick and is attached to the winding shaft. The individual layers of the curtain contain, among other things, intumescent and endothermic (heat-consuming) materials: in the event of a fire, this composite material acts like a heat shield and the curtain expands when exposed to heat.

Fixed field (adaptation to conveyor system at a higher installation position)

The fixed field is attached to the wall like the fire protection closure, encompasses the conveyor system and can be optionally covered with a steel plate. Intumescent materials fill the necessary functional gaps between the fixed field and conveyor system in the event of a fire.

APPLICATIONS

Versatile and approved throughout Europe

Thanks to its heat-insulating properties, the ECClos®-Flex-I only requires the space of its housing and can be used wherever space is limited, e.g. in logistics centres, where there are many gates next to each other and several trucks dock next to each other for unloading. In the automotive industry, the intralogistics opening must be very large, e.g. for the car body. For walls in panel construction, ECClos®-Flex-I requires only a few mounting points. ECClos®-Flex-I is also suitable for use in passageways to other halls, e.g. for use with industrial trucks.

What does the ETA mean for use?

The conveyor system closure ECClos®-Flex-I may be sold and installed throughout Europe. This makes it the first conveyor system closure of textile construction with a European Technical Assessment.

The testing according to ETA places significantly stricter requirements on conveyor system closures than fire tests for conventional floor-closing fire protection closures and fire protection curtains, in particular for the elevated installation position and the enclosure of continuous conveyor technology. The ETA refers to the ECClos®-Flex-I kit. The control technology is not yet internationally standardised, but must be tested nationally in the respective market.

Quality assurance: built and tested

Like every product that leaves the STÖBICH production, the ECClos®-Flex-I also undergoes a quality assurance process: in the first step, self-monitoring takes place in production. The results of this are incorporated into the external monitoring by an independent materials testing institute. The audit procedure is an essential part of the verification procedure.
