Continuous quality in the water management of your building
Water is used in various places within buildings, including for heating, cooling, and humidification. In the kitchen, water is used for dishwashers, coffee machines, and other equipment. All these different applications are exposed to the quality of the supplied water and are subject to it. By pre-treating pipe or source water, a specific water quality is achieved, which allows the subsequent processes to run more smoothly and efficiently. The requirements for water quality can vary greatly. Water that is consumed must meet very different standards than water used for cooling. Below, we detail various applications that may also play a role in your situation.
Air humidification
For an optimal climate, air handling systems are installed in office buildings. The relative humidity can be varied by introducing water. Various techniques are used for air humidification. The most common are: Atomization, Steam humidification, Ultrasonic, Infrasonic, and Hybrid.
Humidifying the air can cause problems due to minerals in the water that accumulate on nozzles or in the humidification section. Viruses and bacteria can also be introduced and transferred to the air through the water. Therefore, water treatment is necessary and is also recommended by suppliers of humidification systems. Depending on the type of humidifier, Wairtec can assist with appropriate techniques such as water softening, reverse osmosis, or disinfection of (pipe) water.
Central heating systems
In a hot water or steam boiler, water is heated or converted into steam. The water used can cause many problems in the boiler itself, the pumps, or heat exchangers. A well-known issue is black deposition (magnetite) that occurs in central heating systems due to oxygen corrosion. Improper pH levels, the use of various metals (Multi Metal), or oxygen ingress can cause excessive corrosion, leading to leaks or blockages. Additionally, an excessive amount of lime in the central heating water will deposit in the boiler or heat exchanger.
Wairtec provides expert advice and supplies equipment and chemicals to “preserve” the system, preventing corrosion and unwanted deposits.
Cooling systems
In a cooling tower, the cooling capacity of water is utilized. When water droplets evaporate, heat is extracted from the environment (= adiabatic cooling). Due to evaporation losses and this adiabatic cooling, water is partially lost. These losses are compensated by supplementing with fresh water. The addition of fresh water increases the concentration of the cooling water, potentially leading to problems with salt deposition and corrosion. In open systems, bacteriological contamination can also occur quickly due to the presence of microorganisms from the outside environment, as well as the entry of contaminants such as leaves, etc.
Legionella safety through UV disinfection
Priority and non-priority institutions are required to ensure the quality of their drinking water. To provide you with the assurance of high-quality disinfection, we developed the L-Safe series. A point-of-entry UV system that ensures the incoming water is thoroughly filtered and disinfected using UV technology. This allows you to comply with regulations and ensures that the drinking water safely enters your collective water network.
