Dehumidifier for Yard Blasting Painting plays an important role in the operation of shipyard.

Control humidity: Ensure that the relative humidity of the operating environment is kept within a suitable range. Excessive humidity will affect the effect of sandblasting and painting, leading to a decline in coating quality, such as blistering, flaking and other problems. Reducing humidity through dehumidifiers can improve coating adhesion and durability.

Prevent corrosion: A low humidity environment can reduce oxidation and corrosion of metal surfaces, especially after sandblasting, when metal surfaces are exposed to the air and easily affected by moisture. Dehumidifiers can maintain a dry environment and reduce the risk of metal corrosion.

Faster drying: After blasting, lower humidity helps to speed up paint drying and shorten job cycles. This is important to increase productivity and reduce waiting time.

Dehumidifiers usually use the principle of cooling dehumidification or adsorption dehumidification.

Cooling dehumidification: by reducing the temperature of the air, the moisture in the air condenses into water droplets, thus reducing the relative humidity of the air. Cooling dehumidifier usually consists of a compressor, condenser, evaporator and fan.

Adsorption dehumidifier: using adsorbent (such as silica gel, molecular sieve, etc.) adsorption capacity of moisture, the moisture in the air adsorbed on the adsorbent, thereby reducing the humidity of the air. Adsorption dehumidifier usually consists of adsorbent container, regeneration device and fan.

Selection Points

Dehumidifying capacity: According to the operating area and humidity requirements of the shipyard, select a dehumidifier with suitable dehumidifying capacity. The dehumidifying capacity is usually measured in litres per day, indicating the amount of moisture that can be removed by the dehumidifier per day under certain temperature and relative humidity conditions.

Applicable temperature range: Considering the temperature changes in the shipyard's operating environment, select a dehumidifier with a wide applicable temperature range. Especially in winter or cold areas, you need to ensure that the dehumidifier can work properly at lower temperatures.

Noise level: Shipyards are usually a noisy working environment, but excessive noise can have an impact on workers' health and work efficiency. Choose a dehumidifier with a low noise level to provide a relatively quiet working environment.

Reliability and durability: Due to the harsh operating conditions in shipyards, dehumidifiers need to have a high level of reliability and durability. Choose a dehumidifier with reliable quality and a well-known brand name to ensure long-term stable operation.

Maintenance and upkeep: Consider the maintenance and upkeep costs of the dehumidifier and choose a model that is easy to maintain and upkeep. For example, some dehumidifiers have an automatic cleaning function, which can reduce the amount of manual maintenance.
