Kaydon Coalescer and Separator Technology

The value of Kaydon coalescing and separator technology is demonstrated in the effectiveness it contributes to overall engine reliability and availability. Reliability equates to maximum operational time, which is a function of reducing downtime, extending time between maintenance, shortening planned maintenance activities, and reducing unplanned shutdowns. Clean fuel is a vital component in providing and maintaining diesel engine reliability. The implementation of Kaydon coalescing technology delivers the fuel quality necessary to help meet challenging diesel engine reliability and availability expectations.  Kaydon offers two series of coalescer elements, the CI-35XXP High Performance series and the CI-35XX series.

CI-35XXP High Performance Coalescer Elements

The Model CI-35XXP family of elements is used for water separation and filtration of diesel fuel # 2. These coalescer elements coupled with a Kaydon Filtration separator element provides a high degree of water removal and polishing filtration.

The CI-3510P, 20P, and 40P design utilizes multiple types of fiberglass in a pleated construction.  Flow rates and efficiencies are increased over traditional fuel coalescers.

BENEFITS

Water Removal: The CI coalescer elements provide water removal efficiency that exceeds ASTM D975 Diesel Fuel Specification (1), and this equates to maximizing uptime for your diesel powered equipment.

Particle Removal: The CI-35XXP coalescer elements offer an added benefit of particulate removal in addition to water removal.

Modern Technology: The CI-35XXP version merges the latest media technologies, construction methodology, and Kaydon Filtration innovation. This advancement in coalescing technology provides customers increased engine durability and protection, reduction of equipment failure rates due to contaminated fuel, and extended on-engine filter life.

CI-35XX COALESCER ELEMENTS

The Model CI-35XX coalescer elements are used for water separation and filtration of diesel fuels.  The CI coalescer elements coupled with a Kaydon Filtration separator element provides a high degree of water removal and particle filtration.   

The CI coalescer elements offer a simple and efficient solution for diesel fuel conditioning.     

BENEFITS   

Particle Removal: The CI coalescer elements offer an added benefit of particulate removal in addition to water removal.  The first stage of the coalescer element is prefiltration, which is constructed integrally within the coalescer element.  By providing a prefiltration stage, the coalescing fibers are protected, which extends service life and helps maintain water removal efficiency. 

Water Removal: The CI coalescer elements provide water removal efficiency that meets ASTM D975 Diesel Fuel Specification, and this helps provide expected uptime for your diesel powered equipment.

SEPARATOR ELEMENTS

Kaydon Filtration separator elements are used for today’s critical diesel fuel filtration applications. Kaydon Separator elements are designed and constructed with special hydrophobic materials to provide a barrier to water coalesced with Kaydon filtration CI-35XXP and CI-35XX coalescer elements.

BENEFITS

Exceptional Water Removal Efficiency: Kaydon Filtration separator elements prevent water droplets from passing downstream. Helps provide water concentration in diesel fuel to below ASTM D975 500 ppm requirement, and when coupled with a CI-35XXP coalescer, can attain levels to 130 ppm (total water content).

Reliable Construction: The separator elements use high quality components and are constructed using proven manufacturing methods. Longstanding and established Kaydon filter element designs keep the separator fuel element functioning in demanding fuel applications.

Cost Effective Solution: Kaydon Filtration separator fuel element provides effective Life-Cycle Costing) (LCC)# . Factors such as element life, fuel cleanliness levels, equipment reliability, and reduction of fuel related failures contribute to credible savings and productivity.

# Life Cycle Costing (LCC) — Total cost associated with the use of a filter element. This takes into account cleanliness of fuel, filter life, change-out frequencies, and operator involvement. Cost of the filter element alone does not give a true evaluation of the overall cost.

Total Water = Free, Emulsified, and Dissolved Water

Total Water Content totals the individual categories of free water, emulsified water, and dissolved water. Always insist water content analysis in be analyzed as “total water content” in parts per million (ppm).  (Total Water Content analysis should be performed per ASTM Method D6304-16e1)

Total Water Content exists in diesel fuel # 2 in three forms:

1) Free Water - This is water that has separated from the fuel and has descended to low points in fuel tanks and piping. This form of water is most damaging.  It is water in excess of that soluble in the fuel and appears as a separate phase.

2) Emulsified Water - These are a form of free water that is suspended or free floating in fuel.  This is water that appears in the fuel as haziness (cloudiness), or as minute droplets. Emulsified water has difficulty, either due to addition of biodiesel, additives, or excessive agitation, to be removed by centrifugation or water separators. This water is damaging to engines. 

3) Dissolved Water - Water that has absorbed into the fuel. Fuel will always contain dissolved water. Fuel will hold as much water within itself until it becomes fully saturated, and when additional water is added, the excess water will release and disperse as free floating water. If temperature and/or humidity increase, more water will be absorbed. If the temperature and/or humidity decrease, fuel holds less dissolved water.

Maximum Dissolved Water Level

The capacity for moisture absorbency of diesel fuel # 2 increases as temperature increases. Over the temperature range of 4°C (40°F) to 35 °C (95°F) with 75% relative humidity, the saturation moisture (dissolved water) level of diesel fuel # 2 ranges from 40 ppm to 120 ppm. The increase in moisture absorption as the temperature increases is approximately 2.4 ppm/°C. ^ However, moisture absorbency may also be affected by other factors such as fuel bending practices and additive packages.
