GE Energy seeks toxic fume and aluminum dust collection system

GE Energy’s 750,000 sq ft plant in Salem, Virginia is dedicated to manufacturing turbine components and control equipment for the industrial and power industries. GE required a solution to capture toxic hexavalent chromium fumes generated from their stainless steel welding process. The grinding and deburring of various steel and aluminum components created an airborne aluminum dust hazard which required the use of both dry and wet dust collection equipment to eliminate airborne particulate in the facility. GE’s dedication to workplace safety and a clean environment has ensured that welders and operators are protected from welding smoke and aluminum dust.

Challenges of Hex Chrome and Combustible Dust

Diversitech’s local sales representative visited the facility and met with the maintenance supervisor in charge of the project. Measurements were taken to determine the correct type of equipment for the project. All applications were analyzed by Diversitech’s applications engineering group to propose the optimal solutions for GE’s hexavalent chromium and aluminum dust collection requirements.

Metal Grinding made safer with high efficiency HEPA filtration

After careful analysis of GE’s steel-grinding and deburring areas, Diversitech proposed four 5′ x 10′ downdraft tables equipped with electronic height adjustment system, able to support 2000 lbs of weight. This system allowed operators to work at the best working height depending on part size and operator height. The table also included a start/stop floor sensor mat to ensure energy-efficient usage: the table is shut off when the operator moves away from the work area. The Optiflow grating option permitted operators to channel airflow only onto areas where they were working. This allowed for better suction. A minihelic gauge was installed, which provides a visual indication for when it is time to clean or replace filter cartridges. The downdraft also included dual high efficiency 99.99% @ .3 micron HEPA after-filters to eliminate all particulate from the air stream.

Aluminum Grinding made safer with wet-type dust collection

For the aluminum grinding area, Diversitech devised a wet type dust collection system to protect operators from airborne aluminum dust, which can be flammable or explosive when in contact with an ignition source. Two 5×5 tables were butted together to create a 5’x10’ ducted downdraft table connected to two 5000CFM wet collectors.

The wet downdraft table included a manual height adjustment system with a 10” range, operated with a manual crank shaft connected to 4 pistons on each table leg. The table also included a start/stop mat to allow seamless operation.

Specialized solutions for welding stainless steel

GE controls and power electronics also purchased 4 FRED 01-Ts for their stainless steel welding stations, along with a FRED CV6 cartridge dust collector for a spot-welding table. In order for GE to weld very large parts, Diversitech designed a 10’ x 10’ x 8’ galvanized welding booth with an eight-cartridge environmental booth collector. This booth included fluorescent dust-tight light kits, motion sensors, and an antiflash welding curtain to enclose the booth. By custom-engineering the correct equipment for GE’s applications, Diversitech was able to provide a full line of turnkey air filtration solutions for GE’s welding fume and dust collection needs.

“Diversitech was very helpful in providing useful information to solve our particular Dust Collection problem.
Our users have all had good things to say about the product and working with Ron Morris was a pleasure.
He provided all the support we needed in getting our system up and running.
I would recommend Diversitech to anyone that needed a similar product.
It is very well made and easy to use and maintain.”

  • Reduced hazardous dusts from work areas
  • Provided cleaner breathing air for operators

« As a repeat customer, and owner of both wet and dry downdraft tables, we cannot say enough about the products, and the people at Diversitech…….both are a pleasure to work with! »

  • Combustible dust from deburring safely contained with wet downdraft tables
  • Solved excess dust from grinding and finishing steel parts
  • Reduced cycle time by allowing operators to deburr near the machining center

« The tables are now fully functioning! The students were on them yesterday, and the instructors were so impressed. One instructor even said that he’s “old school” and wasn’t sure about the downdrafts, but he was very impressed. »
