Checklist important parameters

Listed below are a number of parameters that are important to consider when selecting the right type and size of random packing in order to achieve an effective and sustainable solution.

Sometimes it is difficult or even impossible to obtain information and data regarding the specific process. Together with our suppliers, we have extensive experience and we can make sound assumptions as a basis for designing the best solution for the process.
