About Us

Carroll Technologies Group has been servicing the mining industry in North America for over 30 years. From its early history in the coalfields of West Virginia, Carroll Technologies Group has expanded to become the largest and best electronic services group in the U.S.A., providing over 800 mines with advanced technology communications, employee and equipment tracking systems, safety monitoring systems, and a broad range of other safety equipment.

Today Carroll Technologies Group and its two operating subsidiaries – Carroll Engineering Co. and Delta Electric Inc.—service the needs of mining companies with a network of 13 distribution centers and Miner Care 24/7™ support offices strategically located in 9 states.

While our roots are planted firmly in Mining we have positioned ourselves strategically for our next phase of growth by establishing new business operations in Green Energy.

Here’s a quick look at our two major business units.


  • Miner safety solutions include tracking and tagging systems which not only locate miners and save lives if disaster strikes but give you day-to-day value by increasing miner productivity and reducing overhead expenses.
  • Communications solutions give mining companies seamless wireless radio communications which links people on the surface with those underground so that everyone’s in touch all the time—a critical need when seconds matter.
  • Custom-built monitoringsolutions provide mining companies the most advanced systems to detect dangerous build-ups of smoke and explosive gases as well as monitoring systems to insure optimal performance.
  • Circuit-breaker and electrical/electronicproducts meet all of a mining company’s electrical requirements.

Green Energy

  • Green Energy solutions help mining companies develop strategies to capture and process methane gases. Having a strategy for carbon mitigation helps the mines position themselves for future regulatory initiatives and enables them to become a player in the emerging carbon offsets markets.

Carroll Technologies Group serves customers who operate 24/7. That’s why we drive our team to be on the spot with the right products at the right time, backed by MinerCare 24/7™ support.
