Damaged EquipmentFuel, neglected & left over time, will break down and form abrasive carbon particles that will damage your hydraulic & fuel system(s). Suspended particles in your fluids cause as much damage as if you used a pneumatic sand blaster. The key factor is maintaining healthy, clean, fluids to prevent costly breakdowns.
Fuel Testing ProceduresFuel testing procedures and job walks allow us to get to know our customer and the jobsite conditions to meet the needs of the application.
Fuel ConditioningFuel conditioning services are available using magnetic technology to keep your fuel in optimum condition.
AppearanceThis gives the customer a visual aid to how clean the fuel is.
Dissolved Water by K.F. ASTM D6304Water is identified by measuring the total and entrained water through coulometric titration. It draws the water out and measures it. Water causes hot spots, engine failure, knocking engine, lose BTU, heat combustion, loss of power, exhaust issues and cylinder wear.
Water should be less than 0.1%.
Cetane Index ASTM D976Cetane Index is a measure of a diesel fuel’s ignition quality.
Cetane index limit – 40 minimum, anything above 40 is good.
Sediment & Water ASTM D2709Water & Sediment in fuel can cause corrosion, wear, bacterial growth and premature fuel filter clogging.
The amount of water in fuel should not exceed 500 ppm (0.05%).
Sediment should not be greater than 100 ppm (0.01%).
Stability/Accelerated Aging Du Point F21-61Accelerated simulation gauges the durability of the fuel and how well it ages with time. It is exposed to elemental changes to show what it will do. As it ages it has a lower tolerance level to withstand engine conditions. The PSI in the middle and bottom of the fuel tank contribute to the fuel falling out of spec. Negatively effects emissions, BTU, combustibility and engine failure.
Stability/Accelerated Aging Initial – no limit
Stability/Accelerated Aging Final – up to 2.2. Above 2.2 is elevated and indicates possible aging of fuel. (The result is a value that is calculated by Du Point F21-61 method.)
Sulfur ASTM 5453Sulfur content will affect SOx emission and can have adverse effects on many NOx and PM emission reduction devices. The amount of sulfur allowed in diesel fuel is regulated by the government. Bulk delivery of diesel fuel should be tested to include sulfur levels.
Sulfur – 15PPM (ultra low sulfur)
Modular SystemOur modular system design(s) allow for portability of our equipment while maintaining the commercial and industrial grade quality assurance.
A Broad Range of ServicesWe offer services for simple jobs with silicate based material (dirt) suspended in your fuel and we can add multiple layers and options allow us to handle situations where multiple problems (water contamination, algae, fuel breakdown) have arisen.
API Gravity ASTMD1298API Gravity is the measure of a diesel fuel’s density, or weight per volume. The higher the API Gravity, the less dense the fuel. API Gravity can provide valuable information about a fuel’s composition and performance characteristic’s including power economy, low temperature properties and smoking tendencies.
API Gravity 30 – 40 desired
Corrosion Copper StripAccelerated simulation of the corrosive effect the fuel is having on the copper engine components.
Between 1-3 are normal.
Distillation, IBP ASTM D86
Distillation temperature is the temperature at which 90% of the fuel volume can be distilled off. This temperature is directly related to the fuel’s volatility and therefore, its’ Cetane Index, density, flash point and viscosity as well. A #2 diesel fuel’s minimum distillation temperature should be approximately 300° F and its maximum should be approximately 700° F.
- IBP outside limit: A sample with an initial boiling point that is below limit may tend to contain lighter end product within fuel. Fuels having too low volatility tend to reduce power output and fuel economy through poor atomization.
- 50% outside limit: A result that exceeds 50% distillation limit may have tendency to cause smoke formation. Give rise to objectionable odor. Cause lubrication oil contamination and promote engine deposits
- FBP outside limit: Those fuels having too high distillation may reduce power output and fuel economy through vapor lock in the fuel system. Inadequate droplet penetration from the nozzle.
- 10% Distillation – no limits
- 50% Distillation – 450 – 536 F.
- 90% Distillation – 540 – 640 F.
Flash Point ASTM D93Flash Point is the lowest temperature at which the vapors of a combustible liquid will ignite momentarily in air. Low diesel fuel flash points indicate contamination by more volatile fuels such as gasoline.
Flash point should be 120 – 185 F.
Microbial Growth Microscopic Culture GrowthAtmospheric and water borne microbial organisms. They double in length every 20 minutes. They consume the combustion properties of the fuel. Causes filter clogging, they excrete acidic compounds that mixes with water to increase the corrosion of the tank and engine.
