Water quality and system performance

Good water quality is central to protecting closed-loop heating and cooling systems from corrosion, scale and performance loss. eleXion’s chemical-free approach helps systems meet recognised water quality guidance, including VDI 2035 and VDI 6044.

Plan for the Future
Emerging UK guidance, including HNTAS TS1, also reflects the growing move towards chemical-free systems, also referred to as “Depleted Water Systems”, and controlled water quality management.

Why switch to chemical-free water treatment?

Chemical dosing has been the standard approach for closed-loop heating and cooling systems for many years.

Today, growing sustainability expectations, evolving industry guidance and a focus on reducing maintenance are driving the shift towards chemical-free treatment strategies.

By maintaining stable system water conditions, it helps protect performance without ongoing chemical dosing, monitoring and disposal.
