The NOVA technology
We are heralding in a new era in the world of greases
Turning everything we've learnt so far on its head. Greases based on the NOVA technology does not adhere to our previously mentioned rules and principles on choosing a product based on base oil viscosity, NLGI ratings and calculations.
So what exactly is the difference between RENOLIT NOVA greases and grease based on conventional thickener?
Part of the performance relates to the additives and their function. The thickener in conventional greases (such as lithium or lithium complex grease) has a higher polarity than the additives, and it is therefore hard for the additives to reach the metal surface.
In 'functional thickeners' (such as calcium sulfonate complex), the additives are more integrated into the thickener. They may work slightly better, but that does not fully resolve the problem of enabling the additives to reach the metal surface.
In RENOLIT NOVA greases, however, the additives reach the metal surfaces and can do the job more effectively. See the figure, which provides a general overview of this.
A whole new world of opportunities is opening up
When you can use the same RENOLIT NOVA grease for slow-moving bearings under heavy loads as for fast-moving bearings, all kinds of new opportunities open up. This is a relatively new technology and we are constantly expanding our knowledge in applications for these greases. With the experience we at FUCHS LUBRICANTS have amassed to date, there is great potential for reducing the number of greases needed in an industrial company that has varying requirements on grease performance in different applications.
There are many applications where conventional grease does not work well enough. When it comes to resistance against over-rinsing with aggressive chemicals and water, the adhesion and low solubility of RENOLIT NOVA greases are why they are good problem-solvers in such cases. A longer re-lubrication interval and reliable operation contribute to lower costs for maintenance, yet another argument in favour of these products' performance.
Where can the RENOLIT NOVA greases be used?
Some examples are industries where there is contact with process water and/or acids, bases or metalworking fluids. This includes bearing lubrication in rolling mills, and alkaline environments in the paper and pulp industry, where RENOLIT NOVA offers excellent adhesion, good sealing capacity and excellent corrosion protection.
RENOLIT NOVA can contribute to a better environment in applications where the lubrication interval can be extended. The products are also suitable in various automotive and marine applications. For instance, the RENOLIT NOVA greases are good alternatives to lithium based greases, where the price of lithium could increase and access decrease as the use of lithium increases in the electronics industry.
There are far more applications than the examples mentioned above, and we are constantly expanding our experience around the products.
