The cleaning is one of the most important industrial activities for the handling of shutdowns. The turnaround teams of the Rohrer Group have been internationally known for their cleaning services in the case of shutdowns for years. Cleaning works in the case of large-scale shutdowns can be handled reliably and timely with our own capacities of up to 400 people and approximately 80 high pressure units and suction vehicles.
During projects of this size up to 600 heat exchanger bundles are cleaned within a period of approx. 3 weeks by means of semi-automatically controlled bunch cleaning devices.
In order to optimise the procedures and to be able to work even more efficiently and faster, individual traffic, logistics, and cleaning yard concepts are developed for each project.
The high-pressure water cleaning is especially suited for the removal of hard and tough residues from containers, pipelines, heat exchangers, columns, reactors and the like.
The Rohrer Group counts on the use of semi-automatic internal and external cleaning systems for high-pressure water cleaning of tube bundles. These systems are adapted to the individual requirements and reach maximum efficiency both for the external and the internal cleaning of pipes with the highest occupational safety standard.
In the process industry, the high-pressure water Technology has proven to be the most efficient and most ecological cleaning procedure for the customer for the internal cleaning of containers of any kind and size including possible fittings (agitators, standpipes or fill level tubes, heating coils, floors, baffle or guide plates, etc.). Only water without chemical additives is used.
The cleaning of pipelines by means of high-pressure water technology is indispensable because of the variable application possibilities and high cleaning performance from the process technology for the process technology due to the variable applications and high cleaning performance.
The Rohrer Group offers the complete spectrum of waterjet cutting for on-site use, with the cuttable materials ranging from alloyed metals to steel, concrete and reinforced concrete to high-strength ceramics.
Dry-ice blasting is a cleaning procedure where dry-ice pellets are blasted onto the surfaces to be cleaned by means of air pressure.
Among other things, CO2 blasting offers the great advantage that the devices and plants to be cleaned cannot be damaged by moisture and the surfaces remain intact.
Due to its small size, the equipment is very mobile and can be used in a versatile manner which is optimally suited for cleaning works under confined space conditions (furnaces, electrical workshops, pump stations, etc.).
Mobile air conveyor systems, so-called super suction devices, are able to suck out or blow fluid, solid or dusty media with maximum power.
The Rohrer Group has been working for decades with special vehicles for the suction and the transport of hazardous substances and dangerous liquids.
Apart from the pickling technology, the Rohrer Group specialises especially in the chemical purification and degassing of plants in chemistry and petrochemistry.
Optimum protection of plants, machinery and the environment are a fixed element of contaminant cleanup. All restoration work is carried out in accordance with the stringent legal requirements. Substances harmful to the environment and health such as asbestos crop up more often than you think during restoration work. This is why contaminant cleanup should be carried out by experienced companies who are aware of this responsibility.
