ADH 6000

Description

The quality and useful life of anti-corrosion painting is determined by several factors, and the pretreatment and protection of treated surfaces against moisture are the most important factors. Surfaces that have been blasted are completely unprotected against corrosion and must not be subjected to excessive humidity or to the risk of condensation.

The rate of corrosion is high above a certain value of the relative humidity – the critical humidity. Below the critical humidity the corrosion rate is negligible. The critical humidity is about 60%, but it should not exceed 50% in practical situations.

In practice, it has been found that dehumidification is a crucial factor for anti-corrosion painting. The cost of dehumidification is only approximately 4% of the total treatment cost of corrosion preventive painting of a ship’s tanks. Moreover, dehumidification is often a pre-requisite for the correct execution of anti-corrosion painting. This is especially crucial in the painting of blasted surface of a ship’s tanks.

SPEEDO Dehumidifier is engineered specially for internal tank blasting and coating operations in equatorial and tropical climate conditions. The unit also comes complete with a specially designed control panel and can be easily transported by crane or forklift.
