Manufacturer of Plasma Grow Lights For Indoor Agriculture Requires EMI Air Vent Panels

THE CHALLENGE
A manufacturer of large scale commercial indoor agriculture developed a unique, low energy optimized light spectrum indoor grow light. The manufacturer needed a vent to cover the dual light bulbs, and some other EMI/RF shielding was required to project the control electronics as well as reduce device emissions. 

DESIGN REQUIREMENTS
Limited real estate; very thin media required
Location directly under bulbs necessitated the need for a porous shielding media to allow for heat loss
EMI/RF shielding of electronics components

KEY CUSTOMER REQUIREMENTS
Airflow and EMI shielding
Cost effective
Engineering design and support

CONCLUSION
Due to the unique design constraints on this application, traditional honeycomb vent media was not an option due to the limited amount or real estate to work with. 

Our engineers came up with a 50 openings per inch (OPI) stainless steel mesh instead, which represented a unique manufacturing challenge being able to secure the flexible mesh to the vent frame. The frame was then grounded to the chassis via a CHO-SEAL® S6305 conductive elastomer in a groove.

THE SOLUTION

Parker Chomerics designed a vent to cover the manufacturer’s light bulbs, which provided much needed air flow as well as EMI shielding. 

Since traditional honeycomb media wouldn’t work for this application, we designed a 50 openings per inch (OPI) stainless steel mesh instead, which represented a unique manufacturing challenge being able to secure the flexible mesh to the vent frame. The frame was then grounded to the chassis via a CHO-SEAL® S6305 conductive elastomer in a groove.
