OK so it’s not instrumentation or automation per sé but we were intrigued with this product and application. Many of our visitors working in industry would be familiar with the problems this product may alleviate and so we decided to cover it on the Signpost.
Nanolia is introducing a product that enables virtually any machine to operate more efficiently, while reducing fuel costs by around 11% and emissions by around 60%. Based on the latest German nanotechnology the product which is simply added to engine or gearbox oil is a low cost way to reduce the cost of operating machinery – from the smallest motors and generators to the largest marine diesel engines and including pumps, gearboxes and winches. It can even be used to good advantage to save the cost and extend the life of company vehicle fleets. One application, the company says, is good for 100,000 Kms – even if the oil is changed many times in that period. And after 100,000 Kms, it can be simply reapplied to further the vehicle’s life.
The product – Rewitec – which is not classed as a fuel or oil additive – is a nano coating that actually prevents engine metal wear so that gears, pistons and bearings became almost maintenance free with extended service life.
These “smart coatings” are amazingly easy to apply and have a major positive impact for factory and plant owners, logistic and fleet operators, helping drive sustainability, efficiency and cleaner air.
- Longer lasting engines / vehicle gears, pistons and bearings
- Fuel Efficiency: around 11% savings on fuel
- Cleaner air / emissions reductions (on average 50-60%)
How does it work?
Theoretically, lubricants work by creating a protective film that avoids direct contact of the metallic surfaces. However, lubricants are not able to protect the metal surfaces under all conditions and permanently. This new nano coating technology works rather differently. It actually modifies the surface texture of frictional metal parts and creates a new, very smooth metal silicate coating. This metal silicate coating reduces friction and increases efficiency, especially in older engines and gearboxes. Due to optimisation of compression pressure in engines, oil- and fuel consumption, emissions and CO2 exhaust gases are reduced.
The synthesized metal silicate compound only has to be added to the original lubricant and is carried to the affected areas of the engine or gear box. In the abrasion area, the metal silicates react due to high temperature and/or high partial pressure and conjoin with the metal surfaces, filling the smallest corrugations, pores or micro cracks in the metal surface, forming an extremely smooth and solid metal silicate layer. The treated metal silicate surfaces have a much lower friction coefficient and allow for a better and faster build-up of a lubricating film. The effect on wind turbines, for example, is well documented and significant in terms not only of extended gearbox life but also increased power generation.
