Client Challenge

Client Challenge

A European environmental equipment manufacturer approached Tml Industries to collaborate on the development of a modular air purification component customized for industrial applications. Their current solution exhibited deficiencies in adsorption efficiency for volatile organic compounds (VOCs) and demonstrated inconsistent manufacturing quality across different batches. They sought a partner capable of assisting in the redesign of the core filtration media and facilitating scalable, cost-effective production that adheres to international compliance standards.

Tml’s Solution

Tml’s Solution

Tml Industries proposed a new approach using spherical activated carbon as the core filtration media, which offers increased surface area and uniform porosity compared to conventional granules.

Over a six-month collaboration, Tml led the R&D process through the following phases:

1

Material research

Internal lab teams developed a formulation of spherical activated carbon with optimized binding agents to enhance durability and performance.

2

Prototype development

Multiple sample batches were prepared for VOC absorption testing and airflow resistance validation.

3

Customer collaboration

The client was actively involved during prototype reviews and material testing cycles to ensure application-specific fit.

4

Tooling & production

Dedicated moulds were created for the modular filter housing and frame, allowing seamless integration into the client’s existing system footprint.

5

Compliance testing

The final product passed EN and ISO air purification standards for industrial facilities.

Results

Results

The successful completion of this project enabled the client to launch an upgraded version of their filtration equipment line, thereby creating new opportunities in public infrastructure tenders throughout Scandinavia.
