Keep your cooling water safe  –  make disinfection more efficient.

Hinwil, Switzerland 01-11-2016 – SWAN on-line analyzers continuously measure the dosing of disinfectants such as free chlorine, monochloramine, total residual chlorine and combined chlorine to efficiently monitor biological contaminations.

Cooling water conditions tend to promote the growth of hazardous bacterial contamination such as Legionella.

In order to effectively control and inhibit the development of bacterial contamination (e.g. Legionella) and their host organisms, it is essential to implement on-line analyzers at critical control points in order to continuously guarantee safe cooling water conditions.
The SWAN on-line analyzers AMI Codes-II CC and AMI Codes-II TC are turnkey instruments to continuously monitor the dosage of free chlorine, monochloramine, total residual chlorine and combined chlorine in cooling water.

AMI Codes-II CC and AMI Codes-II TC:

  • Broad measuring range of 0.05 to 10 ppm
  • Automatic zero calibration for long term stability
  • Maximum functionality with combined measurement of free chlorine, monochloramine and total chlorine and combined chlorine
  • No precipitation of the reagents due to high salt concentration


Keep your cooling water safe with SWAN’s on-line analyzers.

At SWAN, we also believe in balancing economic success and social responsibility. In this light, SWAN sponsors both global and local projects to give back to society at a community level. In 2016, SWAN helped to improve various waste water treatment projects, such as in Benin and assisted in providing wholesome and clean drinking water in regions where water is considered a precious commodity. Projects like these are also dedicated to the eradication of diseases and aim to educate local communities about the use of proper water handling and establishing basic hygienic rules. The combination of this knowledge with the provision of competent and efficient drinking water and sanitation services are known to have a catalytic effect on social change and improvement.


Project name: Quali'Eau

Project area: Departement Alibori, Borgou and the city of Parakou

Project duration: 2016 - 2019

SWAN Launches New Monitor AMI CACE

Acid conductivity monitoring - No more resin changing required

Hinwil, Switzerland 04-10-2016 – SWAN has re-invented the conductivity measurement with an attractive blend of reproducibility and performance, lowering resin consumption and significantly minimizing time and costs spent on maintenance.
AMI CACE continuously measures conductivity, before and after cation exchange, as well as determining the pH value of the sample and alkalizing reagent concentration.
The online monitor AMI CACE will be a key component of current and next generation water steam cycle instrumentation as it enables significant cost savings at increased instrument availability.

  • No resin changing or resin rinse down time required
  • Low maintenance
  • Continuous monitoring of sample flow and sample temperature
  • Short response time for the detection of anions

Continuous on-line reproducibility of 5 ppt which enhances our ultra-high measuring range of silica trace levels in ultra-pure water


Hinwil, Switzerland 17-08-2016 – SWAN’s AMI Silitrace Ultra is a unique product solution that embodies continuous reproducibility with ultra-high accuracy in the on-line monitoring of silica concentration in ultra-pure water (UPW), to ensure the integrity of product quality.


  • Measuring range: 5 ppt (0,005 ppb) to 25 ppb
  • Reproducibility: ± 0.005 ppb or ± 5%
  • Continuous and automatic monitoring of main instrument functions such as: sample flow, reagent supply and process integrity
  • UPW concentrator (patented “Carrcentrator” or Reversed Osmosis System created by SWAN AG in partnership with Intel Corporation)

The AMI Silitrace Ultra is the only product of its kind, capable of combining a measuring range of 0.005 ppb - 25 ppb, previously only obtainable through sample testing in analytical laboratories, with an on-line and continuous reproducibility of ± 5 ppt. Knowing true contaminant levels at all times is crucial for gap free data accumulation and valuable (future) trend analyses.
This is due to the fact that the AMI Silitrace Ultra uses the UPW concentrator technique; an evidence based method that enhances our powerful on-line silica analyzer to continuously monitor real silica levels in UPW up to 40 times more accurate. This technique uses the innovative UPW concentrator (Carrcentrator), which was created by SWAN AG in partnership with and patented by Intel Corporation.

SWAN’s 25th Anniversary

11-06-2016 – SWAN celebrated its 25th anniversary.
As part of the celebrations, SWAN marked its anniversary with two events inviting the public, customers, suppliers and distributors from all over the world to its headquarters in Hinwil, Switzerland.
The first of these events was an Open Day where company tours were given to its guests to provide a first-hand and an in-depth impression of SWAN’s capabilities. Various inter-company departments had the opportunity to explain the processes and stages which each product passes through before being shipped. They got to see the story behind the instruments and innovation at the R&D department where the cutting edge of new ideas are being developed.

Further highlights were the visiting of the immaculate craftsmanship of sensor manufacturing, the assembly of the final instrument and the wet bench.
This proved to be an exciting experience, showing the region’s most innovative and progressive side.
The program was completed with a company presentation of SWAN Systems’ engineering services.

The second day of the program was the absolute highlight for SWAN and its employees, where colleagues from all over the world were flown in to come and celebrate the company’s 25th birthday. The magnitude of the event in combination with some great weather were the perfect ingredients for an amazing atmosphere. Circus Monti was hired to help shape this day to something that will be remembered for a long time to come by building 2 huge tents outside of the headquarters. The ceremony commenced with drinks and social interactions followed by a sit-down dinner and fantastic performances of the Monti acrobats.
