Why is the humidification system of a high-temperature constant temperature and humidity machine prone to scaling? Maintenance skills sharing
Date: 2025-12-19Read: 1
High temperature constant temperature and humidity machineWidely used in laboratories, electronic manufacturing, pharmaceutical storage and other places with strict requirements for environmental temperature and humidity. Their humidification systems often use electrode or electric heating humidification methods to increase air humidity by heating water to produce steam. However, during long-term operation, the humidification system is prone to scaling problems, which not only affect equipment performance but may also shorten its service life.
Analysis of scaling causes
The fundamental reason for scaling is the mineral composition in the water source. Tap water usually contains soluble inorganic salts such as calcium, magnesium, and bicarbonate. When water is heated and evaporated, these substances cannot escape with the steam, but instead deposit on the heating tube, electrode, or inner wall of the water tank, forming a hard scale. Especially in high temperature environments, the evaporation rate of water accelerates, the rate of mineral precipitation also increases, and the scaling phenomenon becomes more severe. In addition, if the water quality has high hardness or has not been filtered, the risk of scaling will significantly increase.
Maintenance skills sharing
Use softened water or purified water: A more effective preventive measure is to avoid using regular tap water. It is recommended to install a water softener or directly use deionized water or distilled water as a humidification water source to reduce mineral content from the source.
Regularly clean the humidification system: Even if softened water is used, the humidification tank, electrodes, and water level probe should be checked once a month. Special descaling agents or diluted white vinegar can be used to soak and remove existing scale. Do not use hard objects to scrape to avoid damaging components.
Timely replacement of consumables: The electrode rods of electrode humidifiers are consumables, and severe scaling can affect conductivity efficiency. It is recommended to replace them according to the manufacturer's recommended cycle.
Enable automatic drainage function: Some of the better models are equipped with automatic drainage and flushing functions, which can regularly discharge concentrated water and reduce sediment accumulation. It should be ensured that this function is enabled normally.
Strengthen daily monitoring: pay attention to equipment operating current, humidification efficiency, and alarm prompts. If a decrease in humidification, frequent water shortage alarms, or abnormal increase in energy consumption is found, it is likely that there is a scaling problem and immediate maintenance is required.
In short,High temperature constant temperature and humidity machineAlthough it is difficult to completely avoid scaling problems in humidification systems, scientific selection of water sources, standardized maintenance operations, and regular maintenance can significantly delay the scaling process and ensure stable and efficient operation of equipment. Good maintenance habits not only extend the lifespan of equipment, but also ensure the accuracy and reliability of environmental temperature and humidity control.
