Product Overview<\/h2>\n

GZZ Series Shipyard Painting Dehumidifier is a mobile integrated dehumidification system specially developed by Gaozhen for shipbuilding, steel structure and heavy-duty painting applications.<\/p>\n

The system combines refrigeration dehumidification technology and rotary desiccant dehumidification technology to provide complete humidity control, cooling, heating and ventilation functions in one compact unit.<\/p>\n

With a robust structure, flexible connection design and easy lifting and transportation, the unit is designed for outdoor all-weather operation under harsh industrial environments.<\/p>\n

During shipyard sandblasting and painting processes, excessive humidity can cause rapid flash rust on steel surfaces, affecting coating adhesion and corrosion protection performance.<\/p>\n

The GZZ Series maintains stable outlet air conditions under challenging inlet conditions from -5\u00b0C to 40\u00b0C and 50%RH to 95%RH, achieving outlet air temperature of 20\u00b0C~28\u00b0C and relative humidity \u226445%.<\/p>\n

With airflow capacity ranging from 6,000 to 35,000 m\u00b3\/h, it is an ideal solution for continuous fresh air supply, mobile operation and plug-and-play humidity control in painting applications.<\/p>\n
