RENISO WF Series Highly-refined, selective baseoils containing a special antiwear additive system. The WF Series is used to lubricate small hermetically sealed compressors, in refrigerators, especially those operating with the refrigerant R 600a (isobutane). Low viscosity RENISO WF products can increase system and energy efficiency.

An important characteristic of a used lubricating oil is its neutralization number. An increase of this value often indicates acidification of the oil. Experience has identified neutralization number thresholds above which the risk of damage rises rapidly (corrosion, copper plating, damage to windings, etc.).

RENISO TES 100 Highly-refined, paraffinic mineral oil. As a result of the good viscosity-temperature behaviour of RENISO TES 100, it is recommended for turbo-compressors.

RENISO Refrigeration Oils Synthetic Refrigeration Oils Alkylbenzenes (AB) RENISO SP Series RENISO S 68 Chemically and thermally highly-stable alkylbenzenes which are specially treated. This treatment will improve the chemical stability, the cold flowing properties and the thermal stability. As a result of favourable solubility with HCFC, RENISO SP products are recommended for R 22, R 502 and similar CFC’s as well as for R 22-based drop-in refrigerants. RENISO SP oils are not suitable for use in NH3-systems. RENISO S 68 is recommended for NH3-applications (Reniso S 68 – without AW-additives). RENISO S 68 can also be used with CFC’s.

Polyalphaolefins (PAO) RENISO SYNTH 68 Thermally-stable poly-α-olefins (PAO) with excellent cold flowing properties. Synthetic lubricating oil for NH3-systems and high-performance compressors. Especially for deep evaporating temperatures. RENISO SYNTH 68 has excellent cold flowing properties. It can be used in plate evaporators at deep evaporating temperatures and small pipe diameters. RENISO SYNTH 68 can also be usend in CO2-applications (not miscible with CO2).

RENISO Refrigeration Oils The Service Program LAS – Laboratory Analysis System for Refrigeration Oils Focused on the specific requirements of refrigerants, FUCHS offers a Laboratory Service which is designed to monitor the condition of refrigeration oils in use. This support service helps to guarantee the reliable operation of refrigeration plants.

Logistics System for Refrigeration Oils RENISO refrigeration oils are ultra dryed. PAG and ester oils are hygroscopic, i.e. due to their polar molecular The LAS-kit contains the necessary equipment for 5 analyses in the FUCHS laboratory. The determination of viscosity, water content, the amount of abraded elements present, the neutralization number (ammonia system: total base number has to be determined) enables the on-going monitoring of a refrigerating system. The LAS can help to reduce maintenance costs and allow countermeasures to be taken in good time if danger signs are registered. Our “LAS for Refrigeration Oils” information pack describes the scope of the tests and the analyses performed.
