KLUBERFOOD NH1 74-401

Synthetic long-life, high-temperature grease for the food and pharmaceutical industries.

As a food producer or manufacturer of machines used in the food processing industry, you have to take care of many aspects: from machine reliability to compliance with regulations, from simplification of maintenance processes to cost savings. Klüberfood NH1 74-401 was developed for the lubrication of production facilities in food and pharmaceutical processing plants where incidental contact with the product cannot be excluded. With this product we have combined the high performance and load-carrying capacity of a synthetic base oil with the versatility of an innovative polyurea thickener. By using Klüberfood NH1 74-401 you can therefore attain long relubrication intervals in a large number of applications. Furthermore, this hightemperature grease offers you a wide service temperature range and can be applied in rolling bearings up to 160°C, or even at short-term peaks up to 180 °C where relubrication takes place at appropriate intervals. Klüberfood NH1 74-401 is NSF H1-registered and complies with FDA 21 CFR § 178.3570.

Klüberfood NH1 74-401 can be used in many different foodprocessing sectors, e.g. bakery, pasta, beverage, meat and fish, tobacco, cereals, grains and oils.

Applications include:

drive roller bearings in ovens and proofers
conveyors and motor bearings
roller bearings in packaging and labelling machines
camshafts, linear guides, and with sliding movements
Klüberfood NH1 74-401 is not approved for use in infant formula processing as this is not a focus market for this product.

Klüberfood NH1 74-401 can be applied by standard commercial grease application equipment, e.g. spatula, grease gun or via centralised lubrication systems.

Before applying Klüberfood NH1 74-401, all lubrication points should be thoroughly cleaned to ensure maximum hygiene conditions. This is highly recommended to ensure food-safe lubrication.

If the production process does not allow cleaning, we recommend the existing grease be replaced by purging the system during relubrication.

Please do not hesitate to contact our technical consulting and sales departments for enquiries regarding grease miscibility, relubrication procedures, etc. If you wish to optimise the service life of your equipment or have any other questions regarding your application, our experts will be pleased to help you.

Enables cost saving and production reliability
due to the prolonged service intervals also at medium to high temperature
due to reduced lubricant quantities even under high loads
Enables reduced number of lubricants and use in numerous applications due to wide service temperature range
NSF H1 registered and in compliance with kosher and halal requirements
ISO 21469 certified – supports compliance with the hygienic requirements of your production
