Product Description Klüber Klüberfood 4 NH1-68
Klüberfood 4 NH 1-15...100 oils are hydraulic oils based on synthetic hydrocarbons. Klüberfood NH 1 oils offer good oxidation stability due to the synthetic base oil, also good stability at low temperatures and protection against friction and wear. They meet HLP requirements acc. to DIN 51524 part 2. Apart from their excellent corrosion stability, Klüberfood 4 NH 1 oils have a good water separation ability. Klüberfood 4 NH 1-15...100 oils are NSF H1 registered and therefore comply with FDA 21 CFR § 178.3570. The lubricants were developed for incidental contact with products and packaging materials in the food-processing, cosmetics, pharmaceutical or animal feed industries. The use of Klüberfood 4 NH 1-15...100 oils can contribute to increase reliability of your production processes. We nevertheless recommend conducting an additional risk analysis, e.g. HACCP.

Application notes
Klüberfood 4 NH 1 oils are miscible with mineral-oil based hydraulic fluids, however we recommend flushing the system with a suitable Klüberfood 4 NH 1 oil prior to initial application in order to comply with food regulations. Flushing at 50 to 60°C removes residues in the hydraulic installation and used oil in the system. Then we recommend changing the filters before putting the hydraulic oil into operation again with the Klüberfood 4 NH 1 oil.
