Heating water treatment and filling
The right heating water quality is crucial to prevent damage and protect warranty claims. Our devices for heating water treatment guarantee compliance with the relevant standards VDI 2035, ÖNORM H 5195-1 and SWKI BT 102-1.
Heating water treatment and filling devices for professionals
No system is too big or too small for us. You can fill systems of any size with our mobile and stationary treatment units. This ranges from minor maintenance work to self-contained heating systems with a capacity of 50 litres to a local heating network with a water capacity of several 100 m³. We have the perfect solution for every heating water treatment requirement. We achieve values that meet all manufacturer specifications and are also suitable for all materials. This is particularly advantageous for the frequently encountered mixed installations.
HVAC specialists encounter a wide variety of premises and conditions. They prepare small quantities for repairs, have to go to hard-to-reach filling locations such as high-rise buildings with self-contained heating systems, or carry out customer services. Our compact small treatment units are ideal for these situations.
For small system and buffer tank systems such as single-family homes, you need treatment units for filling volumes up to 1,500 litres or 50 kW. Simply click through the various solutions for small heating systems.

The water in heating systems plays the most significant role in the smooth operation and service life of the system. The VDI 2035 standard is the working basis for installation, filling and maintenance. On its way through the heating system, the water comes into contact with almost all parts and can cause a huge amount of damage. This starts with oxygen in the system and may include sludge and limescale deposits as well as corrosion.
For small and medium-sized systems with buffer tanks up to 200 kW or 2,000 litres, or up to 3,000 litres with pure system water content, you can get all-in-one units for professional bivalent bypass treatment as well as sludge and magnetite filtration in the hot water section. Safe, simple and flexible.
The filling capacity of these treatment units ranges from 600 to 1200 l/h. They have a capacity of 1350 to 3450 litres to treat water from 420 µS/cm to < 100 µS/cm.

Our treatment units are available for every system size. The heating system manufacturers stipulate strict specifications for water values, otherwise the warranty will be voided. Insurance companies also use these values in the event of damage. In addition to the manufacturer’s specifications, however, HVAC companies should always consider the system as a whole and should ideally follow VDI 2035 to ensure that the treated water is suitable for all materials in the overall system.
Larger units are needed for residential complexes, office or commercial properties, systems of 200 kW or more, CHP units or systems that are transitioning to contracting. Especially in the case of recurring problems with the heating water, you can also set up an all-inclusive package as a stationary system. The units in our Racun range automatically fill, treat and monitor the quality of the heating water.
Once the water quality corresponds to the set parameters, the units switch off. If the water quality deteriorates again, the treatment systems switch on again automatically. You can purchase the units in the Racun range, rent them or have the water treatment carried out by us as a service. You can integrate the unit into the building management system in several ways.

Limescale formation, corrosion and magnetite are common causes of damage when it comes to problems with heating systems. For these reasons, the VDI 2035 standard provides reference values for heating water. These form the basis of many warranty conditions – which planners, installers and operators should always keep in mind. If the relevant guidelines are not adhered to, there is a risk of refusal of commissioning on the part of the manufacturer, rejection of warranty claims in the event of damage, and loss of performance and efficiency.
