II. Current Situations/ Counter Measures Current Situations Air Gun – Cleaning inside Cubicle. System pollution by dust diffusion (spread). . Harmful for human by inhaling spread dust. . Electronic equipment damage by static electricity during Air-Gunning. . Parts damage/ wire cuts by brush cleaning. Inside cleaning after Electricity Off. Due to electricity shut off, causing low productivity & effectiveness, distrust and many more inconveniences. Chemical Cleaners. Not allowed to use in electricity-current. May happen malfunction from wire whitening, distortion. . Polluted diffusion dust repeatedly stick in it. . Dust residue causes another problems. Remarks Counter Measures e-ICM – Cleaning Electric-current Equipment. Allows cleaning without electricity shut-off. . Minimize dust diffusion (spread) in the cubicle. . Enhance performance by cleaning tiny parts. . No static electricity causing. . No damage on parts. Equipment Cleaning during Electricitycurrent. Allows equipment cleaning under 22, 900 V up to puncture voltage of 64, 000 V – by KERI. . Allows stable current without part damages. KERI Certificate Attached. E-Clean with Electricity-current Equipment. Cleaning job under electricity-current condition. . Considering evaporation time for parts safety. . Prevent extra possible trouble without dust residue. 3 ICM Company Ltd.

III. Applications The electric equipment is composed with various parts & wiring in the system… so that… - the electrical & mechanical damages would cause un-stable power supply, - the proper & regular cleaning job of the system is critical to prevent any fine dust, humidity & static electricity on the tiny parts, connections & joints which could cause malfunctions in the entire networks.
