Steam Boilers

A water treatment program adapted to your process needs is critical to ensure adequate steam quality and provide optimal protection of internal components and surfaces of your steam boiler against corrosion and scaling. A well-treated and maintained steam boiler will optimize operational costs by maintaining proper heat transfer and fuel consumption capacities.

Automation of water treatment programs generally represents a key factor for its performance. More stability of the water quality is thus obtained allowing for a better performance of the applied treatments.

Let the specialists from our Equipment division guide you in the selection of the best water treatment approach according to your needs and operating conditions.

Here are a number of our related equipment applications:

Water softeners

Water softening plays an important role in scale prevention in many HVAC system applications. Quality softened water will provide the following advantages:

  • Maintain proper heat transfer

  • Maintain proper flow rate

  • Prevent overheating and tube rupture


Chloride cycle dealkalization represents an effective method for alkalinity removal in steam generation applications. Dealkalization can provide the following advantages:

  • Corrosion control in condensate return lines

  • Clean steam production exempt of volatile chemicals in humidification and sterilization applications

  • A reduction in energy consumption costs in certain applications

Injection Systems

Efficient and safe injection of treatment products is based on the selection of the appropriate equipment. Magnus’ dosing systems are specifically designed for application accuracy and reducing manipulations.

Analytical and Monitoring Equipment

Efficient monitoring of a treatment program benefits from the use of analytical equipment and continuous verification. Automatic surface blow down system and automatic conductivity control unit represents a key component for water quality monitoring in steam generator applications. This type of equipment also takes care of injecting various chemicals, serving to protect the internal surfaces.

Magnus offers innovative monitoring solutions for optimal monitoring at all times.

Neutralization Systems

The need to protect the environment motivates our design team to develop new solutions allowing the responsible discharge of process waste water.

Our automated pH neutralization systems are a perfect example of how technology can serve the environment.

Condensate Polisher

A condensate polisher removes harmful contaminants in condensate returns that can affect the water quality of the boiler. Magnus designs equipment to the specific needs of the steam network.

Cooling Towers and Evaporative Condensers

A cooling tower is an open system allowing to transfer energy by the evaporation of water. In the industry there are different types of cooling towers, each of those have their own water treatment characteristics. Evaporation and exposure to the outdoor elements render this environment prone to scaling, fouling and microbiological growth.

An appropriate water treatment program will ensure the proper operation of your cooling tower and will provide the following advantages:

  • Optimization of energy efficiency
  • Corrosion, scaling and fouling prevention
  • Microbiological control and Legionella prevention
  • Optimization of water consumption

Here are a number of our related equipment applications :

Monitour TM - Automatic feed and monitoring system

The performance of a water treatment program for cooling tower depends heavily on the stability of its application. This can only be achieved by using appropriate injection and monitoring systems.

Because of the massive evaporation resulting from the cooling process, the change of water within the circulation network is quick, typically at a rate of several times per day. Manual control of blowdown and chemicals injection result in large fluctuations of the water quality, which reduce or totally eliminate the effectiveness of a preventive treatment program against corrosion, scaling and microbiological growth.

To maintain satisfactory conditions, it is important to use appropriate equipment to monitor blowdown and chemical feed system.

At all times the equipment must allow the following functions :

  • Control blowdown  by the continuous analysis of water conductivity;

  • Measurement of blowdown and/or make up water volumes;

  • Injection of inhibitors in proportion to water consumption;

  • Scheduled addition of non-oxidizing biocides and bio-dispersant;

  • In line analysis and continuous monitoring of the oxidizing biocide.

Cooling tower filtration

Filtration of water for evaporative cooling towers is a simple and non-expensive method to improve the overall system efficiency. Typically, cooling towers accumulate a lot of airborne particles, slime and scale that can get stuck on wet surfaces and eventually migrate into water.

A typical 200 ton cooling tower, running 1000 hours per year, can accumulate over 600 pounds of airborne and make up particles (ASHRAE Handbook, 2008 Ch 39.13). The cold water sump of a tower offers a perfect environment for the accumulation of mud, which obviously favors the growth of bacteria. The use of a filtration system does not replace chemical treatment but significantly reduces the accumulation of deposits that can provide a favorable habitat to the growth of microorganisms.

Note : Nominal tons of cooling represents the capability to cool 3 USGPM of water from a 95°F entering water temperature to an 85°F leaving water temperature at a 78°F entering wet-bulb temperature.

Design and selection

To properly select a filtration system, it is first necessary to assess the nature of the contaminants to be removed. The particle size and count analysis in water should be part of the design process and equipment selection.  Also the capacity and the volume of the system need to be determined.

The filtration system can be installed through two methods : either on derivation of the cooling tower pump or directly on the basin.

Filtration equipment

Filtration technologies for conventional cooling towers include:

  • Sand (media) filters

  • Self-cleaning screen filters

  • Disc filters

  • Cartridge or bag filters

Closed Loop Heating and Cooling Systems

Water treatment of closed loop heating and cooling systems is equally important for the cooling system's efficiency of a building. Even though they are closed, these systems must be treated to achieve maximum performance and preserve their integrity.

An appropriate water conditioning program will provide optimum corrosion, scaling and fouling control aimed at protecting your assets and optimizing energy efficiency.

Relevant equipment :

  • By-pass feeders
  • OMNIDOSTM automatic chemical feed systems
  • PGM series glycol feed units
  • Cartridge and bag filters
  • Corrosion coupons stations


Suspended particles in water are a major source of contamination and microbiological growth. Magnus offers a complete range of automatic or manual bypass filtration for closed loops.

Injection Systems

Efficient and safe injection of treatment products is based on the appropriate sizing of the equipment. Magnus’ dosing systems are specifically designed for application accuracy and reducing manipulations.
