Global success for Gröninger

The tank cleaning facility located at Den Hartogh Logistics Service Centre Gothenburg, Sweden, has recently been equipped with a latex cleaning unit. Den Hartogh, which acquired the Swedish company at the beginning of last year, performs cleaning and heating activities at the site in addition to transport operations.
Cleaning process
The process of cleaning hardened latex remnants is difficult using a standard high pressure cleaning system.
To mitigate this, Gröninger has developed a fully automatic latex circulation unit dedicated to this purpose, which is continuously being updated and modernised.
By using a heated batch with a chemical cleaning agent, the latex is dissolved in the tank, eliminating the need for any manual work to be carried out. Alongside its customer, Gröninger has been analysing how these operations can be carried out as energy efficiently as possible and has now selected an electric-powered return pump to reduce compressed air consumption.
The unit is placed in a 20ft technical container with a work platform located on top, allowing tanks to be cleaned on a separate bay without disturbing regular tank cleaning activities.
Global developments
The city of Nagoya in Japan, is home to Japan’s largest seaport. As a crucially important transportation hub, Meiko Trans has chosen Nagoya as the location for the construction of a modern tank container depot.
Different types of tank containers will be able to be cleaned at the new depot using a high-pressure system and a low-pressure chemical circulation unit. The layout of the system was designed in close consultation and based on a visit by the Meiko delegation to Gröninger’s headquarters in Rotterdam.
Upon the system’s arrival in Japan, the unit was connected with piping and cabling and commissioned by a Gröninger project engineer.
Container cleaning system Elsewhere, Gröninger has designed, built and commissioned a fully automatic container cleaning system for cotac. cotac has been cleaning intermediate bulk containers (IBCs) and stainless steel containers at the Mannheim site for many years.
Many of the products transported in these containers find their way into the pharmaceutical industry. To safeguard the quality of the cleaning and to make cleaning less labour intensive, Gröninger has completed a fully automatic container cleaning system for the company. The system is equipped to process various container formats. A forklift truck places the container on the stainless steel chain conveyor.
Next, the container is moved automatically through different sections. The section where residual product is removed is connected to an air purification system, where the released vapors are purified.
Both the exterior and interior cleaning are carried out in a closed, fully automated booth.
The associated high-pressure technology is built in a 20ft container. Stickers are removed very quickly using a 500 bar spray gun. Afterwards, the containers are dried with hot air and/or sterilised using steam. Cleaning and process data are processed by a PLC, exported as files, and digitally sent to the customer’s systems. This means that the cleaning history of a container can always be referred to when asked for. The HOYER Group has begun operating its most modern semiautomatic cleaning facilities for IBCs at its Mannheim site in Germany. With new projects in South Africa and New Zealand, Gröninger confirms its role as a global player.
