THE SITUATION
Manufacturers and service providers feel the effect of today’s energy expense and price increases. Most decision makers believe the solution to the problem is to find the lowest available energy prices.
Electric motors waste up to 50% of electric energy due to inefficient motor optimization.
Some reasons for inefficiency include: high ambient temperatures, unbalanced voltage, improper loading, inadequate ventilation, misalignment, vibrations, improper lubrication, and most importantly, contamination.
Contamination is a surface coating that causes electric motors to run hotter than normal. By design, electric motors have cooling fans that draw air over the external shell. If not properly cleaned, contamination will build up over time and clog and defect the motor’s ability to cool itself and run at ambient temperature. Hot, contaminated motors running in these conditions increase the amount of energy and thus, increase the cost the motor needs to operate.
THE PROBLEM
The most common way to clean electric motors is to take them out of service and clean manually with rags and industrial solvents. To avoid this interruption in production, cleaning is often delayed extensively, which leads to an inefficient motor and/or eventual motor failure. Most of the industrial solvents used have a very low flash point, creating a fire hazard and possible outages. They also emit unhealthy fumes and the manual application of the solvents leaves secondary debris such as lint and cloth on the motor surfaces.
Additional methods of motor cleaning include soda blasting, walnut shell blasting and pressure washing or steam cleaning. Soda and shell blasting can be too abrasive for the motors and require a system shutdown. Pressure washing or steam cleaning the electrical system of a hot, running motor can create a highly dangerous situation.
THE SOLUTION
Carmad Industrial LTD is a leading ISN and SECOR certified company, that offers the best industrial, oil and gas, and commercial cleaning services using dry ice. With many years of expertise Carmad Industrial LTD helps customers realize operational efficiencies while reducing energy costs, and provides a quick, safe, non-toxic and economical cleaning solution for facilities, industrial equipment, machinery, machine tools and assembly line equipment.
Dry ice cleaning cleans in-place without major disassembly or cool down and is non-abrasive, non-conductive and non-corrosive. It is a completely dry and clean process as it does not use water. The cleaning media, dry ice, sublimates upon impact, disappearing without adding secondary waste.
