WaterLine RO/ROB - reverse osmosis systems.

In order to protect steam humidifiers and steam generators from deposits of limescale and salt, we recommend using desalinated or partly desalinated water. The reverse osmosis system WaterLine RO/ROB offers a very practical solution.

Product description

Reverse osmosis as a practical solution for plumbers.

With the WaterLine RO/ROB, HygroMatik offers a practical solution for the supply of humidifiers – ready to use and of compact size. The conductivity of the demineralised water can be adjusted according to requirements. Therefore, the demineralised water can be used for both electrode and heater steam humidifiers. Thus, the WaterLine RO/ROB can be used for all HygroMatik humidifier systems. During the reverse osmosis process, the natural osmosis process is reversed using pressure. The demineralised water created in this process is called permeate; the concentrated solution is called concentrate.
