Particulate and Water Removal

 Water removal system

Water removal by coalescing, sometimes referred to as liquid-to-liquid coalescing, removes water mechanically. Water within the fuel bonds with the fibers within the coalescing elements. The small water droplets grow as they pass through the filter structure becoming so large that when they complete passing through the coalescing element, gravity pulls them toward the bottom of the housing. We offer individual filter housings as well as complete skid packages.

The DIGI Field Kit from Parker Kittiwake allows for multiple oil parameters to be measured in the field, and comes complete with the following tests:

Viscosity (Comparative)
The Viscostick gives a simple “go/no-go” result. Typically it will detect 5-10% distillate fuel dilution of an SAE 30 to 40 engine oil as well as increases in viscosity due to oil contamination.

Total Acid Number (TAN)
Testing for TAN is essential to maintain and protect your equipment, preventing damage in advance. This test measures both the weak organic and strong inorganic acids present within oil. A rise in TAN is indicative of oil oxidation due to time or operating temperature. This test kit is supplied with up to fifty tests, providing proper monitoring of TAN level trends. Simple to use drop test (results are displayed by color change) provides the user with easy to interpret results.

Insolubles (Soot)
It is important to monitor combustion related debris and oxidation products. High insolubles will cause varnish formation on hot surfaces, sticking of piston rings and wear of cylinder liner and bearing surfaces. Insolubles also cause the detergent property of the oil to decrease, speeding further deterioration. This test is used to detect insolubles from diesel engine combustion products (such as fuel ash, carbon, partially oxidized fuel, oil oxidation products) and spent lubricant additive. Simple to use, and providing quick and accurate results, this test helps prevent engine damage.

Water in Oil
It is essential to maintain and protect equipment, while eliminating the damage caused by water in oil. The DIGI Water in Oil Test Kit provides state of the art, digital analysis and gives fast, accurate results for easy monitoring of trends.

Heated Viscometer

Parker Kittiwake Heated Viscometer
The Parker Kittiwake Heated Viscometer is extremely rugged and ideal for harsh industrial application. A stand-alone kit, supplied in its own case, provides accurate oil viscosity results in minutes for fast, on-site maintenance decisions

The Parker Kittiwake Heated Viscometer is a condition monitoring tool that enables the user to make informed operational and maintenance decisions about critical plant and equipment. Monitoring viscosity provides an early warning for potential fluid issues. Fuel and lubricating oils form a major cost element in the operation of almost all industrial machinery and engines; the quality must be closely monitored to protect the investment.

The viscosity of oil is regarded as the most important characteristic. The correct viscosity level provides flow resistance, optimum film strength in system clearances, and minimum friction losses and leakage. Viscosity can increase or decrease as a result of problems such as contamination, fuel dilution, and shear thinning. Measurement of viscosity is extremely important for hydraulic oils, diesel engine oils, gear, and fuel oils. Testing viscosity of fuel oil is important for verifying the correct grade of fuel is delivered, for calculating combustion performance, plus adjusting of fuel handling and injection systems. The Heated Viscometer is suitable for testing viscosity of both residual fuel and lube oil from a wide variety of applications including diesel engines, gas and aviation turbines, gear boxes, hydraulics and marine fuels.

The Parker Kittiwake Heated Viscometer is extremely rugged and ideal for harsh industrial application. It is portable, equipped as a stand-alone kit and is supplied in its own case. The ability to test on-site, at the point of use, enables engineers and facilities managers to conduct oil analysis quickly and easily. Detecting out-of-spec fuels or lubricants can identify potential problems before equipment damage occurs.

The heated viscometer measures the viscosity of the oil sample using a ‘tilt’ motion, moving from side to side in both directions. While in motion, an internal rolling ball travels through the sample, using gravity, to calculate the viscosity. This measurement is taken at a specific temperature point.

• Highly accurate, fast results with two readings available at 40°C, 50°C or 100°C
• Test an even greater range of oils, by changing the viscosity index or density
• Ability to test: Unheated with automatic viscosity correction to 40°C, calculated at 100°C for lube oils
