Klüber Klübersynth UH1 4-18 is a fully synthetic, heat carrier oil, lubricating oil for the food processing and pharmaceutical industries


Benefits for your application


– Supports process reliability by use of an NSF H1/HT1 registered lubricant

– Supports the reduction of operating costs resulting from excellent stability for long life
– ISO 21469 certified – supports the compliance with the hygienic requirements in your production plant.




Klübersynth UH1 4-18 is fully synthetic, heat carrier oil for the food processing, pharmaceutical and cosmetics industries. This special oil has good heat transfer properties and it has excellent low-temperature properties. Klübersynth UH1 4-18 is NSF H1 registered and therefore complies with FDA 21 CFR § 178.3570. The lubricant was developed for incidental contact with products and packaging materials in the food-processing, cosmetics, pharmaceutical or animal feed industries. The use of Klübersynth UH1 4-18 can contribute to increase reliability of your production processes. We nevertheless recommend conducting an additional risk analysis, e.g. HACCP.




Klübersynth UH1 4-18 should only be used as heat carrier oil for closed systems in the food processing, pharmaceutical and cosmetics industries. Cast housings and rotating unions are known to have minute leaks when exposed to high temperatures. Thus, these applications require an NSF HT1 lubricant for technically unavoidable contact with the food.


Application notes


Klübersynth UH1 4-18 is to be used exclusively as heat carrier oil in closed systems. At higher temperatures moderate inert gas pressure increases the oil’s service life. Material conventionally used in heating and cooling systems, i.e. steel, spheroidal graphite iron and stainless steel, do not affect Klübersynth UH1 4-18.
