Compressor systems

There are several types of compressors with different requirements to the lubricants wear properties. Most importantly is the chemical and physical challenges the lubricating oil is faced with during the compression process. Compression oil consists of a base oil and different additives depending on the area of use.

Meneral oils
Polyalfaolefines (PAO)
Alkylbenzena (AB)
Di-esters
Polyesters (POE)
Polyglycols (PG/PAG)
Phosphatesters
SIlicone oils

Additive roles:

Reduce friction
Remove heat
Withstand temperatures up to 200°C
Oxydation stability
Anti foaming properties
Air release properties

Refrigeration compressors / HVAC:

The oil in a refrigeration system is designed to remove heat and to lubricate parts in the compressor. Oil must be miscible with refrigerant. Oil products seldom contain classic additive elements due to possible reactions with refrigerant, however the use of ester oils in high pressure CO2 compressors has lead to the requirement of EP additives based on Phosphorus.

Analysis:

Through our analysis we will be able to reveal wear metals, contamination and additive elements and also the chemical and physical properties of the sample. By comparing the these values with new oil and/or previous samples from the same systems we are able to form a opinion of the current state of oil, refrigerant and compressor health.
