Components for Mass Transfer Process
Hewitech develops process-orientated, high-performance product designs for structured fill material for both absorption (chemical & physical scrubbers) and desorption plants, so-called stripping plants. In cooperation with our customers, we also design and install trickle bed reactors and bio-scrubbers.
Together with our team, we advise on the selection of materials to be used, as well as the right types of packages, along with efficient liquid distribution systems.
High process reliability is ensured by the demonstrable high compressive strength together with the special structure of our packages, resulting in a uniform liquid distribution for different liquid loads.
Together with our team, we offer the selection of the materials to be used as well as the right types of packages along with efficient liquid distribution systems.

Features
High-performance trickle fill installations are characterised by their high mechanical strength.
This strength is determined by two special factors, on the one hand by the mechanical and extremely stable connection technology of the single grid and on the other hand by the specially developed material composition of the injected single grid.
The NC 20 series can be delivered in 3 different strength classes (25, 27, 48 kg / m³)
Therefore, the optimal weight class can be provided depending on the customers application requirements. Particular attention is paid to environmental compatibility (solvent-free), simple and fast mechanical processing by means of patented assembly technology.
In addition, every local fire protection requirement is strictly adhered to.
The machines which we developed for processing single lattices are suitable for permanent use as well as for deployment on construction sites under weather protected conditions.
Due to the open vertical-offset grid structure with a free volume of > 97%, these trickle fill installations are particularly suitable for contaminated as well as highly polluted water quality.
Areas of application are cooling towers, agricultural and highly complex mass transfer applications.
