Manufacturing and installation

Our excellent manufacturing and installation quality is based on close coordination with clients and permanent monitoring of all stages of the work progress. This helps avoid mistakes, which, particularly in major projects, can lead to delays and significant costs later.

Delivery and acceptance

Thanks to our excellent logistics service, all venting domes arrived at the building site in time, preassembled and ready to be cast into the reinforced concrete ceiling.

Of course we provide detailed documentation.

Further benefits of the venting domes

• • leak- and weatherproof sealing
• • venting efficiency not affected by snow loads
• • sound and temperature isolation on request

The venting domes represent an economically attractive option for many types of industrial installations, as they can be tailored to individual needs.

Silo retrofits and upgrades

We upgrade existing silos or silo installations for explosive materials, converting them into future-proof storage facilities which meet statutory requirements.

Following a general review of the present condition and risk assessment, we also check currently installed accessories such as discharge systems, filtration equipment or level indicators, as required, and develop a comprehensive concept for the upgrade (including cost estimation, detailed task and time schedule, installation by qualified personnel).

Silo upgrade and retrofit with walk-on blow-out flaps

Several silos in a kaolin plant were retrofitted with walk-on venting panels on the roofs to comply with current ATEX regulations. After a thorough analysis of the initial situation and calculating potential solutions, the vents were eventually fitted into custom-designed roof structures and installed on top of the silos.

Safe upwards venting: the silo roof consisting of several elements tightly bolted together, with built-in blow-out flaps, has proved its worth in almost ten years. It is customized for each application and equipped with walk-on blow-out flaps.

Due to the integrated blow-out flaps, a silo strength up to p_red = 1.5 barg can be achieved.

Rapid silo upgrade with blow-out flaps in mounting frames

In less than two days, our team replaced 18 inappropriate rupture discs at a reinforced concrete silo with rexotec blow-out flaps.

The trick: our pioneering, custom-built rapid-mounting frames, which enable stunningly short assembly times on-site. They were inserted into the existing wall openings - without previously drilled fixing holes!

Of course, the smooth execution of these upgrading works would not have been possible without the meticulous preparatory work done by our experienced staff, including the provision of accurately sized parts.
