Hilite-E Filter Cartridges

For Synthetic Fluids and Oils
Ion Exchange removes acids not additives: longer fluid life.
Description
The Hilite-E ion exchange cartridge line is based on the
existing filled cartridges. Instead of a traditional
activated adsorbent, the cartridge canister is filled with
a dust-free ion exchange resin specifically selected for
acid adsorption.
Users report increased life between changeouts to be
many times greater than other activated adsorbents.

How It Works
The ion exchange media consists of resin beads .3 to
1.2 mm in diameter. They offer low pressure drop and
no dust. Best of all, they contribute no other mineral
salts to the system. Total acid number (TAN) reduction is greater than Selexsorb® media, with a much
longer life reported by users. The ion exchange resin
works as an adsorbtion bed to capture acid ions. A
Hilsorb trap filter or Hilco coalescer may be used
downstream to remove excess water. Low acid
numbers can be maintained without water control.
Optional water control allows the maximum fluid and
cartridge life.

Does Not Remove Additives
Hilite-E ion exchange is an alternate method of treating
phosphate ester fluids and hydrocracked petroleumbased oils for acid reduction and removing oxidation
components.
It is used instead of Selexsorb, fuller’s earth, or activated alumina in fluids that contain additives. Ion
exchange does not remove additives as the activated
adsorbents do.

Features and Benefits
Much longer life
Will not remove additives
Does not react with fluid
Will not contribute salts
No dust migration
Low pressure drop

Where Used
Ciba-Geigy and Monsanto phosphate esterbased fluids are prime candidates for ion
exchange purification because of their
additive content. Canada and Europe favor
ion exchange treatment.
Ion exchange resin can be used for acid
reduction in virtually any application where
fuller’s earth, activated alumina, or Selexsorb
is used. It works especially well in Akzo’s
Fyrquel® and other polar fluids.
