Electric Motors Cleaning & Restoration / Electric Motor Parts Cleaning

CLEANING MOTORS, GENERATORS & SWITCHGEAR

Based in Macon, Georgia, Co2 Blasting, LLC has cleaned hundreds of motors, generators and switchgear from southern Florida to the Arctic Circle. With over seventy years of experience in electric motor repair, we have first hand knowledge of the leading cause of motor and generator failures: environmental contamination.

Dirt, dust and product can build up on windings and lamination vent ducts trapping heat and obstructing ventilation, preventing needed cooling air from reaching the windings and deteriorating the insulation system. Carbon residue in D.C. motors can create flashovers that bring production to a halt. Loss of revenue due to downtime and the costs of motor repairs associated with catastrophic failures can become astronomical.

Dry ice blasting has become the preferred method for removing these contaminates, on site, from the windings of large motors and generators that are too costly to remove from service for cleaning. Motor repair shops also utilize in shop dry ice cleaning to eliminate oven drying time and minimize the turn around time in critical applications where no spare motor is available. The process is also effective on removing contaminates from clogged fan guards and cooling fins of totally enclosed motors, as well as electrical buss, breakers, transformers, switchgear, etc.

With our vast experience and expertise in cleaning rotating electrical equipment, we have implemented procedures to prevent damage to fragile insulation systems, as well as integrating specialized auxiliary equipment to remove moisture from the supply air, thereby providing a true dry process.

Benefits of Dry Ice Blasting Electrical Equipment

• Performed properly, the process is non-conductive, allowing the cleaning of electrical equipment to be done quickly and in place, reducing downtime and eliminating the need to dry components prior to re-energizing.
• The elimination of grit entrapment common with other blast cleaning methods.
• A superior clean. The dry ice pellets can reach nooks and crannies that are difficult or impossible to reach with rags, brushes, chemicals and solvents. This also minimizes disassembly requirements for cleaning access.
• Increased megohm and polarization index values.
• Improved heat dissipation and cooling air ventilation resulting in lower operating temperatures.
