1、A-A-58017 9 Aug 1993 COMMERCIAL ITEM DESCRIPTION Recovery Unit, Anti-Freeze 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
2、 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
3、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
4、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
5、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 ca
6、rbon 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 from 115 volt, 1 phase, 60 Hz, 20 amp outp
