How it works ?
DSS technology is based on special substances - Repairing Surface Modifiers (RSM).
It influences the detail surfaces only, not the lubricants.

Applicability & Advantages
DSS surpasses traditional additives by combining several advantages simultaneously.
F.A.Q.
DSS types
A wide range of DSS products is manufactured to deliver the highest possible performance across nearly all types of mechanisms operating under diverse conditions.
RSM Assortment
Performance tests
DSS was invented in the mid-1980s. Since then it has been deeply improved and patented. Dozens of tests performed on various materials and applications prove that DSS is among the technologies of the present and the future.
Testing results

  • Optimized consumption of fuel, energy, and consumables

    Extended operational life of equipment

    DSS results in 3 to 10% fuel and electricity economy in the engines, reductors, compressors, bearings, transmissions and other mechanisms.
    Mechanical parts lifetime increases by 20 to 100%, in some cases up to 400%.
    The operational lifespan of lubricants is extended by 20 to 100 percent.

  • Repairs without disassembly
    Reduced expenditure on spare parts
    Option to utilize lower-cost alternatives
    This is highly important for uninterrupted manufacturing. In some cases it is possible to restore machinery that is considered completely non-operational because of wear.
    DSS makes it possible to use lower-cost lubricants and spare parts without negative effects on the mechanisms or the quality of their performance.
  • Minimization of equipment damage in incident scenarios
    Improved safety standards
    After treatment, machinery can operate for a period of time under oil-starvation without damage. The operation of internal combustion engines under nominal load, without motor oil, for several hours has been repeatedly demonstrated with no failures and no degradation in parameters.
DSS does not change the original oils and lubricants, implementing insoluble in the lubricants components. These are quite different from the oil and fuel additives.

The substances used are in microscopic quantities (below 0.2%) and remain in the oils and lubricants for a short time (just few hours), without changing the parameters of the original oils and lubricants.

In this way the warranty of new equipment is not affected when DSS is applied.
It is not necessary to repeat the treatment at the next oil changes.

DSS forms a durable metal-ceramic layer on the surface of parts in high-friction zones, which remains unchanged after the lubricants are replaced.

Very small quantities are required. They are determined mainly by the surface area of the high-friction zones, not by the total volume of lubricants.
DSS surpasses metal-filming, graphite, molybdenum, diamond, polymer, and other traditional additives.

DSS forms layer, not film, on the details, which is stable and non-exfoliating in all possible environment conditions.

After applying DSS, the roughness of the friction surfaces decreases significantly (Rz decreases by 3 to 5 times), and the hardness of the surface layer becomes substantially higher than that of the base material.
DSS is originated in the 1980s as a result of research by scientists from Leningrad, Russia. Later it was patented.

The active substances produced today have been continuously improved. At today these are used for more than 25 years and have been tested in enterprises, mines, factories, and on hundreds of very different machines.
