Parker&Velcon SD718 series equivalent Water Removal Cartridges/oil&water separator
1.SD718 series Separators Description
With SD718 series filter element,the dissolved water removal from insulating oil is now possible without the
need for heat and vacuum oil processing systems. Specifically developed for dehydrating oil to be used in
transformers,patented*Superdri cartridges can help utilities reduce expenses and increase efficiency when
processing oil.
Lefilter produce the equivalent,with same specifications.The details are as below:
2.SD718 series Separators Features
• Unique Construction – Specifically designed for transformer oil dehydration.
• High Capacity – Process up to 5,000 gallons of oil or more with a single cartridge.
• Efficient – Single pass water removal to less than 10 ppm total water, or better.
• Versatile – Models available to fit most industry standard housings.
• Safe – Will not remove oxidation inhibitors.
• Cost Effective – Process transformer oil for less than 5¢ per gallon.
3.SD718 series Separators Special Considerations
SD718 series separators are not designed for particulateremoval.Prefiltering through Velcon 1/2 micron
elements is recommended if particle contamination is suspected.They are not recommended for cost
effective removal of free water in insulating oil.If free water is suspected, the oil should be prefiltered
using Velcon Aquacon elements.
4.SD718 series Separators Applications
SD-718 Sereis Separators are designed for oil processing situations where dissolved water in insulating
oil is a concern, and its removal is desirable. Examples of these situations follow:
• New distribution and EHV transformers are typically oilfilled under vacuum. If the insulating oil has a
high total water content, it is also processed through a heat and vacuum system.SD-718 Sereis cartridges can
be used instead of heat and vacuum to dry the oil.
• Repaired transformers are often oil filled under vacuum.Flowing the oil through SD-718 Sereis cartridges
eliminates the need to vacuum process the oil.
• Insulating oil in storage tanks, and tankers of oil that have accumulated a high level of dissolved water
can be recirculated and dried to less than 10 ppm total water using SD-718 Sereis cartridges.
• Use Superdri cartridges for processing oil in other high voltage apparatus that is sensitive to dissolved
water.
• Use SD-718 Sereis separators to help meet processing specifications where dissolved water sensitive dielectric
breakdown voltage test ASTM D-1816 is used,or required.
