We recently released new formulations designed to meet the new, more stringent manufacturer requirements for protecting new GE and EMD Tier 4 locomotives. All products are backwards compatible with older locomotives. Make sure you are ready for your fleets upgrade, call now.
Using traditional procedures, there is no way to determine if a locomotive toilet needs servicing before an odor or sanitary issue occurs while en route from yard to yard.
Unsanitary conditions in the cab mean locomotives get pulled from service, negatively impacting employee satisfaction and, ultimately, revenue.
Are you attending the 2019 Railroad Environmental Conference at the University of Illinois at Urbana-Champaign? If so, on October 22, 2019, between 5:00-6:30 PM, we will be giving a poster presentation on a recent case study at a Class I rail yard. Learn how your rail yard can cut energy & operational costs with ISC during the parts cleaning process.
The rail industry has been on the search for better safety in parts cleaning. Using the ISC 18425, a Class I railroad company experienced lower temperature & pH requirements and a shorter cycle.
Using a combination of the ISC 18425 and DF 4030, the fluid temperature was 40-50°F below the previous cleaning process. This dramatic reduction in the input of heat needed corresponded to an equally dramatic decrease in energy consumption.
Furthermore, the sheer amount of chemicals required for the DMP cleaning process is 50% less than the previous cleaning process used by the Class I railroad company. Also, the wastewater treatment facility reported that no neutralizing acid was required to treat the wastewater. This reduction in chemicals needed for the wash cycle and elimination of neutralizing acid during the wastewater treatment process resulted in significant and ongoing cost savings as well as reductions in environmental impact and safety exposure to facility personnel.
This reduction in energy usage, chemicals needed, and the elimination of the need for a neutralizing agent resulted in a direct cost savings of approximately $100,000 per year.
The ISC chemicals cleaning performance was impressive to the Class I rail yard. The cleaning quality was reported to be better with the ISC chemicals than with the previous chemical formulae. Each part type was observed to have a better overall appearance after cleaning, and the highly machined parts were even seen to have a more noticeable sheen.
Last but not least, the wash cycle time of the ISC cleaning process was analyzed. While some parts took the same amount of time in the cleaning cycle as the previous process, many part types achieved a faster wash cycle time. We conducted tests over a wide range of part sizes and soil loads. From small engine parts to complete locomotive block assemblies and from light oil and grease to baked-on, carbonized soil, ISC’s cleaning process delivered results better than the previous process in cleaning performance.
The partnership of ISC and the Class I railroad was an all-around success demonstrating the success DMP has brought to many industries, including the railroad industry. With the ISC 18425, the Class I railroad company is now seeing a reduction in energy usage, chemical consumption, and wash cycle time. This results in increased cleaning performance and personnel safety. These results also reduced environmental impact.
