RENISO K Oil

Description

The oils of the RENISO K series are highly refined,naphthene-based selective raffinates that have been dewaxed to a great extent for use as refrigeration oils at low temperatures. Because of their high degree of raffination, the mineral oils of the RENISO K series are very resistant to aging, both in contact with ammonia (NH3) and with HCFC.

Application

RENISO K refrigeration oils are used both for conventional NH3 applications with flooded evaporation according to DIN 51 503 KAA, as well as for halogenated chlorofluorocarbons (HCFC) according to DIN 51 503 KC.

Advantages

• High chemical stability with NH3 and halogenated chlorofluorocarbons (HCFC)
• Good cold flow, which insures oil return and optimum efficiency of the system, even at low temperatures.
• No formation of paraffin deposits at low temperatures
• Good solubility with fully and partially halogenated chlorofluorocarbons
• Very low water content

RENISO S/SP

Description

The RENISO S/SP series are fully synthetic, alkylbenzene-based refrigeration oils with antiwear properties for chlorine-containing refrigerants. Sophisticated production processes ensure that the RENISO S/SP products are sulphur- and wax-free. RENISO S/SP products were developed for critical applications especially when good anti wear properties are required. Compared to equiviscous, mineral oil-based refrigeration oils, the followingn wear protection values were established:

Application

RENISO SP products are recommended for use in

• R22, R502 applications and with drop inrefrigerants
  i.e. R401A/B, R402A/B
• heat pumps used to heat tap water
• plants where very high compressor outlet
  temperatures are encountered.
• systems operating with R600a (iso-butane) and
  R290 (propane)

RENISO S 68 is particularly recommended for R717 (NH3) systems. Because of its good solubility RENISO S/SP oils are recommended for R22 or R22 refrigerant mixtures such as R401A/B and R402A/B.

In general, RENISO S/SP oils are recommended whenever other refrigeration oils provide insufficient protection against wear. RENISO S/SP oils are strongly recommended for lubricating heat pumps.

Advantages

• Very high thermal stability
• Excellent ageing and oxidation resistance
• Excellent low-temperature behaviour
• Excellent oil-refrigerant solubility
• Low toxicity
• Excellent wear protection
• Good extreme-pressure (EP) properties

General Information

Because of its additivation the RENISO SP-series is not suitable for the use with ammonia. For NH3 applications we recommend RENISO S 68 which is free of additives.

Product does not contain anti wear additives

RENISO TRITON SE/SEZ

Description

The refrigeration oils of the RENISO TRITON SE/SEZ series are based on synthetic esters that were especially developed for use with chlorine-free, fluorinated hydrocarbons (HFC/HCFC). In contrast to conventional refrigeration oils, these are miscible with the comparatively polar HFC/HCFC.

Application

The RENISO TRITON SE/SEZ series is outstandingly suited for all refrigerant circuits, in which chlorine-free HFC/HCFC refrigerants, e.g. R134a, R404A or R410A are used. Depending on the viscosity, RENISO TRITON SE/SEZ refrigeration oils are recommended for hermetical, semihermetical and open piston compressors and for screw-type and turbo-compressors. RENISO TRITON SEZ 22 is especially suitable for deepfreeze systems operating with R23.

Note

Because of their chemical structure, ester-based oils tend to absorb water. For this reason, RENISO TRITON SE/SEZ oils can only come into contact with air briefly when the system is being filled. The contents of an opened container must be used within one working day.

Advantages

• Stable lubrication film even at high temperatures, outstanding lubricity
• Excellent solubility with HFC and HCFC refrigerants
• Very high thermal and chemical stability in the presence of coolants
• Secure oil return from the system, good heat transfer
• Good viscosity-temperature behavior
• Outstanding flow at low temperatures
• Long oil fill service life
• Good compatibility with gasket materials normaly used in refrigeration technology
