Water Treatment De-ionisation Resin

Thermax Tulsion is the best and most popular window cleaning resin in the world. It features a mix of T-46 and A-33, it combines high capacity with excellent physical properties. It’s the longest lasting resin for pure water use.

Resin costs average between $1 per hour in soft water areas and $10 per hour in the most extreme hard water areas. The more you get the cheaper it is, and it’ll last if kept sealed in a cool area. Hard water blend recommended for those in hard water areas (WA, SA, rural) for extended life to the resin.
