Background
Large, cool metal surfaces like ship interiors and chemical storage tanks must be coated to prevent corrosion. However, high ambient humidity causes condensation on the metal surface resulting in blooming or flash rust, between the time the surface is blasted visually clean and when the coating is applied, leading to premature coating failure.
The practical logistics of coating operation also prevent the immediate coating of the surface after cleaning. While the surface is waiting for the coating, small reductions in surface temperature and the presence of high humidity in the surrounding air inside ballast tank result in condensation, which causes immediate corrosion.
Under these circumstances, the internal ballast tank maintenance is considered as one of the Fleet’s significant maintenance burdens.
KAWASIMA KAT Series Dehumidifier
KAWASIMA provides contractor stable & continuous dry air, which keeps a cleaned metal surface free from condensation indefinitely, guarantees the blasting and coating quality regardless of the weather. The dehumidifier also provides better coatings for end users and lower costs for contractors
Feature
KAT Series Dehumidifier combines the benefits of desiccant dehumidifiers with the cooling of DX air conditioners to treat make up air. Designed to cost-effectively treat 100% makeup air, the system controls humidity on an as-needed basis.
KAT Series Dehumidifier operates cost-efficiently because all of the energy required for the operation of its desiccant dehumidifier is recycled from cooling components.
KAT Series Dehumidifier is designed for transport with all replaceable components accessible through hinged doors and built in supply air duct ports for quick installation of flexible duct work. This rugged container type unit can easily be relocated without the concern of it becoming damaged.
