Abstract. This Commercial Item Description (CID) describes an
anti-freeze recovery system which recycles engine coolants by
filtration and deionization.
Salient characteristics. The unit shall be portable and with
the option of being capable of attaching to radiators without
cutting or splicing hoses. A means shall be provided
indicating when filters should be changed. Additives shall
easily be capable of being added to the purified solution. The
recycled solution shall be capable of being held in a separate
reservoir and/or dispensed from the machine. Additives shall
be capable of being dispensed from the unit in order to restore
the proper silica and corrosion inhibitors. The unit shall be
designed and constructed for withstanding the strains, shocks
and vibrations incident to shipping and operations. The unit
shall be designed to be corrosion resistant and capable of
being attached to all vehicles and trucks.
Filtration will be by a basket strainer for gross particulate
contamination and two cotton-wound cartridge filters with
activated carbon cores for the filtration of finer suspended
solids.
The unit shall be supplied with two ion-exchange tanks. One
tank shall be for the removal of cations from the coolant and
replacing them with hydrogen ions. The other tank shall be for
the removal of anions and precharging them with a hydroxide
ions. Final flow of the coolant shall be through an activated
carbon filter for the removal of gases.
Pump flow rate of 2-6 gallon per minute (gpm).
The unit shall be capable of purifying contaminated ethylene
glycol at a minimum rate of 1 gallon per minute.
The pump and all accessories used on the unit shall be operable
