Klüberfood NH1 94-402: High-Performance Food-Grade Lubricating Grease
Description
Klüberfood NH1 94-402 is a specialized lubricating grease formulated with a highly refined base oil and a calcium complex thickener. It is NSF H1-registered, meeting FDA 21 CFR § 178.3570 standards, making it suitable for incidental food contact in the food-processing, cosmetics, pharmaceutical, and animal feed industries.
By incorporating Klüberfood NH1 94-402 into your maintenance routine, you can enhance production reliability while maintaining food safety standards. However, we recommend conducting a risk analysis (e.g., HACCP) to ensure full compliance with your facility’s safety protocols.
Application
Klüberfood NH1 94-402 is specifically designed for rolling bearings in machinery and equipment used in the food-processing industry, including in the production of grain, meal, and pellet animal feeds.
Application Guidelines
- Can be applied using standard commercial grease application equipment, such as a spatula or grease gun.
- Before application, thoroughly clean all lubrication points to ensure compliance with food-safe H1 lubrication standards.
- If cleaning is not feasible, replace the existing grease by purging the system during re-lubrication.
- For guidance on grease compatibility and re-lubrication procedures, consult Klüber’s Technical Consulting and Sales team.
