Gly-Vak is a "state of the art" premier preventative maintenance chemical used routinely to minimize or ideally, eliminate the formation of urine scale in vacuum toilet waste lines and tanks. By utilizing Gly-Vak as a daily or bi-weekly cleaning task, airline operators can avoid the high costs and downtime of strong acid flushes or power water washes. Ultimately, a rigorous Gly-Vak program will avoid the extremely high costs that result from line clogs and aircraft diversions.
Gly-Vak uses mild acids, proprietary surfactants and gelling agents to create a safe, non-corrosive and highly effective cleaner and line protector. By utilizing foaming technology, Gly-Vak is able to completely coat waste tube walls without the use of costly ice cubes. The product's strong clinging action creates long residence times for the chemical to soften the scale and ready it for removal. The graph shows that the key cleaning agents Gly-Vak are still attached to the pipe walls even after 100 flushes.
The maintenance process is simple. Depending on your maintenance program, just pour the requisite amount of Gly-Vak in each toilet and flush once. As the aircraft sits overnight and through the first flushes the following day, Gly-Vak's penetrating action softens any existing scale and coats the tube walls to impede additional scale deposition. If the operator confirms existing scale build up before starting the Gly-Vak program, a weekly flush with Sani-Tank N will help emulsify and remove softened scale.
