Committed for many years to responsible performance, CONDAT is taking the lead by supplying the industry greater readability on its eco-design lubricant offer. Its innovative self-scoring Lubriscore® grants a number of stars to products showing a virtuous profile on life cycle criteria: Raw materials and design / Production / Transport / Use / End of life.


What about eco-designed tunnel grease alternative?

A 2 stars product: BTG 4602

As leader on the tunneling market, CONDAT has also been keen on offering safer lubricants for this industry. Developed in 2018, BTG 4602 is a grease specifically designed for the protection of the main bearing and the lubrication of the associated seals in tunnel boring machines.

Formulated from high viscosity synthetic esters and lithium/calcium soap, BTG 4602 provides an excellent resistance to water washout and will give an efficient barrier to water/soil ingress. The polarity of the esters helps the creation of a uniform and resistant lubricating film protecting the seals from premature wear.

The specific anti-wear & extreme pressure additivation will offer protection even if the load suddenly increases. The high viscosity index of the esters ensures that the viscosity of the oil remains stable even when temperature varies, hence providing a consistent and reliable protection.

BTG 4602 is readily biodegradable (OECD 301B test) and is formulated without molybdenum. As such BTG 4602 will not negatively impact the excavated soils and will allow their reprocessing.

BTG 4602 is self-extinguishing and will not propagate flame in case of a fire outbreak, ensuring the safety of the operators and the equipment protection.
