EMC Shielding
Design and manufacturing specialist of metallic welded honeycomb to the highest standards suitable for all civil and military shielding applications. Darchem honeycomb gives high shielding efficiency, is lightweight with a low resistance to airflow and has good electrical conductivity. Trace heating elements can be incorporated to give anti-icing capability in temperatures as low as -29 ºC .
Typical examples include:
- Electronic cabinets
- Military equipment
- Laser screens
- Shielding of heating and ventilation ducts
