Lubricants laboratory: analytical validation as the real performance guarantee
Every equipment failure carries a measurable price in unscheduled downtime, component replacement and production loss. Trust in a lubricant cannot rest on commercial promises — it must be anchored in rigorous analytical data that proves compliance with technical specifications on every batch produced.
Analysis protocols specialised by product
Lubricant analysis is a complex technical discipline where each product family demands completely different protocols. A cutting fluid requires different evaluations than a hydraulic oil, just as turbine oils demand procedures completely unlike automotive fluids.
A system integrated with the production process
At Kelpen Oil, lab analysis is not an isolated function — it is integrated into the production cycle in real time. Each sample is tested, digitally recorded and traced from incoming raw material to customer delivery. A result outside specification automatically blocks batch release — no exceptions when performance is on the line.
Specialised analyses for cutting fluids
Viscosity validation for chip-evacuation efficiency
On the KEEN CUT line, viscosity is measured with the Stabinger SVM 4.001 + Abbemat 350 to confirm proper chip removal. Inadequate viscosity compromises cooling and may cause chip welding, leading to rejects and accelerated tool wear.
This equipment simultaneously evaluates viscosity, density and viscosity index, confirming fluid stability under temperature variation during operation.
Anti-corrosion protocols per fluid type
Each cutting-fluid line requires its own anti-corrosion validation:
Straight oils (KEEN CUT 200 and 300):
- Copper strip test with Tanaka AÇO 8
- Detects behaviour on yellow metals (brass, bronze)
- Identifies inadequate activity of sulfur-bearing additives
Soluble fluids (KEEN SOL):
- Iron chips test
- Simulates real contact with machined steel
- Evaluates emulsion corrosion resistance
The PFX-i colorimeter spots discolouration that reveals early oxidation or thermal degradation.
Analytical differences between mineral oil groups
Groups I, II and III: specific validations
- Group I oils (HBP line): Spectrum Two determines the molecular paraffinic structure, measuring aromatic and sulfur content. A higher volume of impurities demands strict oxidative control.
- Group II oils (HBP I line): Hydrorefining reduces aromatics and sulfur. ICP Optima 7000 DV confirms low levels, guaranteeing superior thermal stability.
- Group III oils (HBP S III line): A viscosity index above 120 requires extreme purity analysis. The DMA 4501 Digital Densitometer validates quality.
Synthetic oils: absolute analytical precision
Synthetic products like TURAN S demand detection of extreme metallic contamination. Panalytical Epsilon 1 identifies metal impurities that would compromise their superior characteristics.
Critical analyses for turbines — preventing catastrophic failures
Water contamination as a silent risk
TURBINE MAX, approved by WEG, exemplifies how analytical deficiencies cause catastrophic failures. Steam turbines tolerate zero water contamination.
Titrino Plus evaluates the alkaline reserve (TBN) that neutralises acids from hydrolysis in contact with condensed steam. Inadequate TBN allows the formation of corrosive acids that attack internal components.
Consequences of deficient analysis
An analytical failure in a turbine oil can result in:
- Total power-generation shutdown
- Bearing replacement (costs above BRL 500k)
- Emergency maintenance with production losses
- Rotor corrosion from acid attack
The Cold Cranking Simulator confirms whether the oil keeps fluidity after idle periods.
Expanded validation beyond routine testing
The lab performs in-service failure investigation, elastomer-compatibility studies, performance validation for aerospace, industrial and critical automotive applications.
When specialised demands emerge, we reformulate products with concrete analytical data — never trial-and-error. Every new formulation goes through complete validation before reaching the market.
Digital traceability — the permanent file of every batch
Kelpen Oil's traceability is not manual — it is a digital record linked to the production system in real time. It's not about documenting what was done afterwards; it's recording each step at the moment it happens.
When raw material arrives, the incoming analysis generates an immutable report with the supplier's parameters. During production, temperature, time and mixing conditions are monitored continuously. At the end, the finished product undergoes analytical validation before any release — and a retention sample is stored for future reference.
This means any question about a batch — weeks or months after delivery — has an answer based on real data, not memory or estimate.
What the lab can detect
Four capabilities that define the level of analytical control:
The Pamas Automatic Particle Counter identifies contaminants from 4 µm — 17 times smaller than the diameter of a human hair. In high-pressure hydraulic systems, particles in that range cause accelerated wear on pumps and valves with no visible sign.
Spectrum Two (PerkinElmer) generates a complete spectroscopic profile of every lubricant — a chemical signature that identifies adulteration or cross-contamination invisible to conventional viscosity or colour analysis.
The Cold Cranking Simulator (Canon) reproduces temperatures down to −35 °C to confirm that startup viscosity does not prevent safe equipment activation — relevant for any application in cold climates or cold rooms.
The ICP Optima 7000 DV analyses 23 elements simultaneously in under two minutes. That speed allows integration with the production flow without creating an analytical bottleneck — real-time control, not post-hoc.
Kelpen Oil: quality documented by rigorous scientific analysis
The distance between a lubricant that protects and one that fails lies in precise analytical control. Our laboratory structure with modern equipment ensures every specification is met without compromise, eliminating operational risk and ensuring continuous protection.
