Through long-term project delivery, the company has built a technology portfolio centered on Floor-Standing Double Membrane Gas Holders, Tank-Top Double Membrane Gas Holders, LIPP Tanks, External Steel / Internal Membrane Gas Holders, and Tar-Free Biomass Gasifiers.

MOTET MATERIAL DATA

Membrane materials & performance evidence

The inner membrane retains gas; the outer membrane provides weather protection and is held in shape by support air. These material options support project-specific selection, not a universal specification for every holder.

Options are references, not a performance ranking. Permeability values under different temperatures or test conditions are not directly comparable.

Compiled from membrane technical data for project-specific material selection.

These are material data, not MOTET test reports, whole-holder certification or contractual guarantees. Material permeability is not whole-holder leakage. Selection also requires gas composition, temperature, loads, interfaces and fabrication conditions; approved project and batch documents govern.

R&D Team

Engineering Teams Behind the Technology

These engineering visualizations illustrate collaboration from field checks and design review to commissioning; they do not depict specific employees, clients or projects.

Field Engineering Coordination

Field checks align the membrane, perimeter anchoring and equipment interfaces before design confirmation and delivery.

Engineering Design Review

Drawings, membrane samples and equipment interfaces are reviewed together to keep design, manufacturing and installation aligned.

Commissioning and Verification

On-site checks cover the control cabinet, support-air equipment and connections before controlled commissioning verifies system response.
