Greyhound Deionised Water 20L
Greyhound Deionised Water is a multi-purpose, highly purified water with almost all of its mineral ions removed. Specifically, deionization strips cations such as sodium, calcium, iron and copper, along with anions such as chloride and sulfate, so the water stays exceptionally pure.
Because the process uses specially manufactured ion-exchange resins, it produces water similar to distilled water. Moreover, deionization is quicker and avoids scale build-up, so it suits batteries, cooling systems and sensitive equipment.
High-purity water for batteries and cooling systems
For example, the low mineral content prevents scale in radiators and batteries. In addition, the purity protects sensitive components. As a result, equipment runs cleaner. Therefore, maintenance drops. Furthermore, the water mixes cleanly with concentrates and coolants.

Independently Lab Tested | Certificate of Analysis
Our deionised water was independently tested by WearCheck, a SANAS-accredited laboratory, in August 2026 (report WAT/27/0358). The certificate confirms conductivity below 1 mS/m and dissolved metals below detectable limits | true deionised purity for batteries, cooling systems, inverters, laboratories and industrial use.
