Dry Ice Blasting Service -  Established in 1995



No Moisture, No Dryout, No Corn Cobs

Motors or genereators, switchgear, stator or rotor windings, armatures or field poles, AC or DC: dry ice cleaning is established as the safest, most economical method to clean rotating electrical equipment. Winding contaminates such as oil, dried paper, dirt, dust and carbon are easily removed with non-conductive, non-abrasive, moisture free dry ice cleaning.

Cryo Services was started in 1995 to utilize dry ice cleaning technology to clean large motor windings. Our staff has 25 years of rotating electrical repair service.

Dry ice pellets are accelerated through a blast system to the surface being cleaned and upon impact dissipate as a moisture free gas. The dry ice is non-abrasive and the contaminate is removed from the windings through a combination of kinetic energy and gaseous expansion.

Motor windings show significant megg-ohm and PI test improvements along with decreases in operating temperature after dry ice cleaning. One rule of thumb suggests for every 10 degree celsius rise in operating temperature, a motor's operating life is reduced in half. Periodic cleaning can reduce motor tempertures and help discover problems such as loose connections or wedges, embrittled insulation, clogged vent holes, and corona damage.

We typically work in conjunction with your present motor repair vendor on motors that are too large to economically remove. The best cleaning method is still to remove the motor from service and have it steam cleaned and baked out, but using dry ice is the best method for field cleaning.

Our dry ice cleaning service has been successfully utilized to clean switchgear, transformer bushings, breakers, relays, distribution buss and substation components.
