2H MASSdek® PACKINGS Effective and economical ENEXIO Water Technologies is one of the leading manufacturers of structured PP and PVC packings for mass transfer, cooling tower construction and water treatment. In order to meet the special demands involved in mass transfer applications we have developed 2H MASSdek® packings. For the last 100 years components with defined and optimised contact surfaces have been used in thermal process engineering, and structured packings represent the most current state of the art. They are indispensable in distillation and have almost completely replaced...

STRUCTURE BRINGS EFFICIENCY Functional principle and characteristics 2H MASSdek® packings have been developed especially for thermal and chemical separation processes and are used for applications such as gas scrubbing, the cleansing of exhaust air, rectification and desorption (stripping). Design Structured packings are characterised by their regular form, which ensures a defined distribution of gas and liquid throughout the pack. As the channels run in opposite directions, the gas and liquid flows are separated at their intersections and then re-mixed. 2H MASSdek® packings consist of...

TECHNICALLY OUTSTANDING – FINANCIALLY CONVINCING Energy saving through reduced pressure drop Due to their optimised design 2H MASSdek® packings have proven to be outstanding compared with other mass transfer equipment – in particular random packings. This technical superiority also has its financial effects. For the same separation performance 2H MASSdek® packings achieve better results in all cases with regard to throughput capacity and pressure drop than random packings. Depending on which random media is taken for comparison, 2H MASSdek® packings reach considerably higher values. The use...

DESIGN AND ENGINEERING Individuality and attention to detail guaranteed The principle is always the same: Gas and liquid should come into close contact across an exchange area as large as possible. However, there are considerably varied detailed requirements which have to be taken into consideration in order to successfully and economically carry out the separation process in each case. For this, it helps to not just have the correct packings but also the associated equipment and the necessary technical design. Our experts cover this range of tasks perfectly. Extensive experience in the...

OPTIMIZATION OF INDIVIDUAL DESIGN Design software 2H MASSdek® Pro For the individual design of our 2H MASSdek® packings we use software developed by our own IT specialists. It permits the hydraulic design of water-air systems and also freely defined systems. In addition, calculations on absorption and desorption for approx. 400 components are possible. The simple operation and extensive data base of the software enables an experienced technician to quickly optimise the process design. On request, we will be happy to provide you with this planning tool. Product development – also for...

2H MASSdek® COLUMN INTERNALS One-stop solution Structured packings can only make full use of their technical benefits compared with a random packing when all installations, the apparatus and the components have been precisely coordinated with each other and harmonised to the appropriate process at the planning and basic engineering stage. The aim must be to find a successful and profitable solution for the separation task in question. . In addition to our support in the process engineering planning of the basic design, we are also happy to review an overall concept which has already been...
