AT&T Power Systems
AT&T Power Systems builds energy systems and power supplies for telecommunications and electronic data systems. CFCs were used in three ways. They were used for bulk cleaning of electronics, in electronic lubricants and aerosol cans used for spot cleaning.
The CFCs used for bulk cleaning of electronics were replaced with Electrovert Aqueous cleaner. The CFC free lubricant that AT&T now uses is Monsanto's 0-138+ isopar-H carrier. Finally, aerosol cans were replaced with low pressure alcohol cleaners.
In 1989 AT&T used 103,000 pounds of CFCs, it now has completely eliminated the use of CFCs.

Surplus equipment was obtained and used for this change. The new cleaning agents costs 150% less per year than the CFCs they replaced. Since CFCs have been replaced, TRI reporting costs have declined.
