WaterLine RO – 
Reverse osmosis systems.

Before our drinking water is fed into the water pipes, it flows through numerous different layers of rocks. Depending on the region, it therefore contains more or less minerals such as calcium and magnesium. If this water is used, for example, in steam humidifiers for air humidification, it can accumulate in the form of lime and salt deposits on the heating elements and damage them.

 

But not only lime and salt crystals are removed from the water by the cleaning process. The water treatment with a WaterLine RO system is also a very effective protection against viruses and bacterial contamination in air humidification and cooling systems.

Basics and how it works

Effective protection for
air humidification and cooling systems

Reverse osmosis water treatment is an effective protection for all air humidification and cooling systems. It reduces salts and lime that exist in nature and prevents the formation of viruses and bacteria in the duct systems.

REDUCES LIME
AND SALTS

Before our drinking water is fed into the water pipes, it flows through numerous different layers of rocks. Depending on the region, it therefore contains more or less minerals such as calcium and magnesium. If this water is used, for example, in steam humidifiers for air humidification, it can accumulate in the form of lime and salt deposits on the heating elements and damage them.

 

For this reason, we recommend precautionary water treatment with a WaterLine reverse osmosis system from a hardness level of 18.8 °e (268 ppm). Harmful deposits can be reduced by up to 95%.


The maintenance effort and thus the operating costs of air humidification and cooling systems can be noticeably reduced by water treatment and the average operating time is significantly extended.

AVOIDS VIRUSES
AND BACTERIA

But not only lime and salt crystals are removed from the water by the cleaning process. The water treatment with a WaterLine RO system is also a very effective protection against viruses and bacterial contamination in air humidification and cooling systems.


Viruses and bacteria present in the water are filtered out by the process of reverse osmosis – even before they reach the air humidification systems. This prevents them from spreading and being released into the room air.

 

For this reason, the integration of a system for water treatment using reverse osmosis is particularly recommended when planning air humidification systems in hygienically sensitive application areas.

HygroMatik WaterLine reverse osmosis function

What happens at the reverse osmosis process?   

In the reverse osmosis process, the water to be treated is forced under high pressure through a semi-permeable membrane with pores less than 0.001 μm. This makes it possible to separate undesirable components of tap water, such as viruses, bacteria, minerals, pesticides, hormones and heavy metals from the water molecules.


Result: Permeate - water with an above average high degree of purity.

Product description

Hygienic, easy to maintain, durable –
HIGH-QUALITY COMPONENTS

 

DURABLE PRESSURE EXPANSION TANKS

The generated permeate is stored in a pressure expansion tank. The pure water is simply and efficiently kept at a pressure of 2-4 bar and is available to supply the air humidification system as required. Seven sizes can be combined depending on the design of the system. The 18 and 40 litre sizes are supplied for wall mounting with brackets and fixing materials, all larger models are supplied with stands.

UV DISINFECTOR FOR MAXIMUM HYGIENE

An UV disinfector ensures maximum hygiene conditions. The lamp irradiates the permeate flowing through with UV rays and very effectively removes any biological contaminants still present, such as bacteria, viruses, moulds, spores and yeast fungi.

 

The procedure is a purely physical process without the addition of chemicals and is therefore easy to handle, harmless to health and easy to maintain.

ANTISCALANT DOSING PUMP

To prevent the lime and magnesium residues present in the raw water from being deposited on the membranes and impairing their performance or shortening their service life, the integrated dosing pump with adjustable timer function injects an antiscalant into the raw water pipes at fixed intervals. The HygroMatik Pragmaclean 309 antiscalant complies with the German drinking water regulations.

 

Antiscalant protects the membrane and extends its lifetime by up to five years.

WaterLine ROC (Reverse Osmosis Compact)

Compact in 4 performance classes from 25 to 140 l/h

MANY FUNCTIONS – SIMPLE OPERATION

The integrated control and operating unit with its clearly laid out display enables convenient and simple operation of the WaterLine ROC system.

 

  • Display of fault and operating messages
  • Maintenance indicator and operating hours counter
  • Conductivity display (permeate) with adjustable limit value of maximum permissible water conductivity (safety shutdown of the system can be capitalised if the limit is exceeded)
  • External release via potential-free contact possible
  • Programmable forced flushing
  • Integrated pressure switch

Optional functions and components:

  • Adjustable blending unit to increase permeate conductivity
    (when used with electrode steam humidifier and optional conductivity sensor)

    (with wall bracket – stand pressure expansion tank possible on request)

 

SPACE-SAVING WALL MOUNTING AND QUICK INSTALLATION

The WaterLine ROC can be mounted on a load-bearing wall in the tightest of spaces. To make the installation as quick and easy as possible, the entire system is supplied on a corrosion-resistant mounting plate ready for connection. It is attached to a load-bearing substructure via 4 mounting points (Ø 10 mm).
