PROPEL Oil Management is a comprehensive approach to managing the lubricant lifecycle.

Professionally Renewed Oil Prolongs Equipment Life


Lubricant renewal can be undertaken either off-site or on-site, and CTG are happy to discuss with you which service location is best suited to achieving the required result.

New Oil – Delivered to customer once new oil is sampled to benchmark additive levels and cleanliness.

Condition Monitoring – is used to identify and monitor the lubricant remaining useful life (% RUL) and contaminant levels. Tests are conducted to ASTM Standards and can be measured on-site by trained CTG representatives.

Reporting –% RUL (remaining useful life) testing, trending and reporting, will highlight the rate of lubricant additive depletion and estimate when pre-determined limits will occur. Once the % RUL lower limit approaches, the lubricant requires renewal. A CTG representative will discuss test results with you and organise lubricant treatment.

Oil collection – If oil is to be treated off-site, oil collection is organised and returned to a CTG treatment facility.

Oil sludge – Renewal stage 1 – If present, sludge contamination will initially be removed before beginning the renewal process.

Fine filtration – Renewal stage 2 – Initial oil filtering is used to remove particle contamination. Up to 3 independent filters can be used in sequence to filter contamination particulate down to as low as 1 micron to achieve the customers required cleanliness at customer discretion (a human hair is 70 microns in size).

Oil dehydration – Renewal stage 3 – Using our exclusive Vacuum Dehydrating Oil Purification System (VDOPS) the lubricant is heated to 66°C and dehydrated under vacuum. At such low temperatures the vacuum dehydration technology vaporises the water from the oil and it is removed without any risk of burning the oil. Moisture levels down to 20 parts per million (0.002%) in oil can be achieved.

Multi pass – CTG’s 5 pass procedure ensures lubricant is comprehensively treated to achieve the best ISO cleanliness result possible.  Filters remove 99.9% of their rated micron size in just the one pass, while oil dehydration removes even closer to 100% of water in the multi-pass procedure.

Testing – filtered and dehydrated oil is tested using ASTM Standard procedures for cleanliness and moisture content.

Additional pass – If required the lubricant may be passed through the process again to ensure final cleanliness and moisture content targets are achieved.

Additive blending – Once lubricant targets are achieved, lubricant additives are blended to restore the lubricant to as good as new (or higher) specification. A final oil sample is taken and kept on file for future reference by CTG or customers.

Certification – Viscosity, density, viscosity index and ISO cleanliness are measured for certification of the finished lubricant to the required Standard for new oil. A Certificate of Analysis is available to the customer upon request.

Oil delivered back to customer – If treated at a CTG facility, the finished lubricant is returned to the customer.
