Why Aquatest?

Vapor-Tek developed Aquatest as a solution to the corrosive effects of water sitting in sealed systems like sprinklers, fire extinguishers and heating systems.  Wherever water is in contact with ferrous metals there is a risk of corrosion.  Over time this can cause particles of rust to flake off and build up, potentially clogging valves and pumps and risks weakening pipes, joints and tank bodies with catastrophic results.

Simply adding 2-5% Aquatest to water used to fill a sealed system renders the water completely non-corrosive and extends the life of the metal parts considerably.  In some applications, e.g. steel drum reconditioning, concentrations as low as 0.2 – 0.5% can prevent flash rusting during a power wash.

Residual water which inevitably pools in pipework, pumps and pressure vessels after cleaning or pressure testing can allow corrosion to eat away at the metal underneath even when the items are not in use.  Adding Aquatest to the testing water or final rinse means any water left behind will be completely non-corrosive and ensure the integrity of the product until it is next used.
