Containment Technology GmbH

Containment Technology GmbH is a German company developing and manufacturing industrial air filtration and containment solutions. CT's specialty are self-cleaning HEPA filter systems, which are used in multiple industries for filtering dust-laden and contaminated air.

History

In 1969, Mr. Kalman Andrasfalvy sen. signed a license agreement with the Nuclear Research Center in Karlsruhe (today knows as Karlsruhe Institute of Technology KIT) for the development of a two-stage HEPA filter, which supposed to be used to filter radioactive dust particles from atmospheric air. The key requirements were to protect the operator at all times and to avoid the contamination of the environment.

Further development and worldwide patent applications followed worldwide, until in 1975 Mr. Kalman Andrasfalvy jun. (today Managing Director of Containment Technology GmbH), further developed the nuclear air filtration systems to be used in multiple industries and applications, whilst maintaining the requirements that are standard in the nuclear industry. The result was the first generation of self-cleaning HEPA filter systems, built to filter process air with extreme dust loads, with a filter efficiency of H14 EN1822.

In 1976, first version of the self-cleaning HEPA filter systems were installed in multiple chemical production facilities, to filter hazardous dusts in compliance with COSHH (Control of Substances Hazardous to Health). First applications were used to filter dusts containing cadmium, asbestos and led.

The first self-cleaning HEPA filter systems specifically designed for the pharmaceutical industry were indtruced in 1978. This allowed the safe manufacturing and processing of API's (Active Pharmaceutical Ingredients).

CT's engineering team further fine-tuned these filter and containment systems until 1989, to further adapt to the needs of the pharmaceutical production. This included a fully redundant filter design, able to operate fail safe 24/7 from OEB 1 through 6, in order to avoid any cross-contamination during the production process.

In August 1993 a study was done by the Nuclear Research Facility of the Karlsruhe Institute of Technology (KIT), on the performance and effectiveness of CT's self-cleaning HEPA filter systems.

In 2007, new standards have been defined by developing smart control and monitoring systems for a variety of self-cleaning filter systems.

Technology

Core of CT's technology is a two-stage, self-cleaning HEPA filter system, designed to handle even the highest dust loads of up to 100g/m3/h. First, coarse particles in the airflow are separated by means of a cyclone effect, whilst the smaller dust particles move towards two specifically designed HEPA filter cassettes, of which one acts as a redundancy, ensuring a constant filter efficiency of H14 according to EN 1822. The remaining dust particles remaining in the filter cassettes is periodically blown out of the filter cells, with high pressure air. This ensures that the filters are never blocked and remain efficient over a long period of time.
