With due consideration given to market demands in respect of averting of ice built up on lower part of rail car body and underbody equipment in winter period “CTG” has developed technologies of deicing treatment.

This recirculation technology called “ANTIL” prevents the lower parts of cars and underbody equipment from corrosion and protects them from snow adhesion, and correspondingly, from ice built up, thus minimizing risks of emergencies caused by ice built ups and providing personnel with fast access to equipment for maintenance. Besides, disruptions of trains schedule caused by icing of the lower parts of cars and underbody equipment, as well as time required for ice removal are excluded.  

The use of proposed “CTG” technology and designed “ANTIL” complex equipment makes it possible to reduce in several times, in comparison with traditional methods, both energy resources consumption and time for deicing treatment of the train. To implement this method no special premses are required – all works may be performed in the open air. Treatment process is automatic and equipment is characterized by low operational costs. Moreover, there are no special requirements for “ANTIL” equipment complex installation place. Assembling and start-up operations are performed in short period.

The effectiveness of deicing treatment with the proposed complex is achieved by supply of the chemi-cal agent under the high pressure on treated surface, further cleaned by removal of extra water, mud and admixtures for further use. Propylene glycol water solution heated up to 85оС operated in recircu-lation mode, which temperature may be reduced up to 35оС in the course of operation is used as chem-ical agent.

The proposed solution:

• Effectively – the obtained results on “ANTIL” deicing technology implementation for high-speed trains “Sapsan” underbody treatment have ensured reliable operation in the winter period. Rate of treatment speed has exceeded several times the possibilities of tra-ditional treatment by air or water. 
• Cost efficient – “ANTIL” series complexes are mounted in the open air and are completely automatic, thus providing the minimum capital investments and maximum operational costs savings (energy consumption is lower than with traditional treatment by air or water in times).  
• Functional – depending on problems stated “ANTIL” series complexes may have different technical “architecture”, ensuring both the preventive treatment, and removal of ice built up and snow, as well as it provides with possibility to treat only the specific places of railroad cars.
