DH Tech utilizes refrigerant-style and desiccant-style dehumidifiers to control the humidity inside a storage tank so the contractor has optimum conditions to blast the surface, clean the surface, and coat the surface of the tank.

Listed below are the benefits that can be attained from using dehumidification if the contractor and DH Tech, Inc. work closely together to make sure the process helps to make your project successful.

Benefits of Dehumidification:

• Enables customer to work 24 hours a day / 7 days a week
• Reduce tank out of service and scheduling time frame
• Humidity and temperature control to "HOLD THE BLAST"
• Eliminate the traditional blast, clean and prime everyday cycle
• Improve production rates and quality of work
• Eliminate or reduce weather related work delays
• Allow a monolithic spray of each coat under proper climatic conditions
• Extended life of coatings due to application under optimal conditions

In today's fast pace industry, using a dehumidifier while doing an internal lining can benefit your project as well as help make sure your project stay on time and under budget.

Environmental conditions such as humidity and temperature have a very substantial impact on cleaning and coating operations. In some instances, coating work must be delayed because of humidity and temperature. In other cases, humidity and temperature are controlling factors in the cycle of blasting and painting. Painting must be accomplished on a surface the same day it is cleaned so that flash rusting does not occur.

Both delays and the necessity of cleaning and painting the same day adversely impact protective coatings work. They make the work more costly and they can diminish quality in the coating operation. Therefore, in some instances, environmental controls can be useful in improving both the economics and the quality of coatings work. Environmental controls include heating, ventilation, creation of protective enclosures, lighting, and dehumidification. To learn more about dehumidification as a process of controlling the environment, read "The User's Viewpoint". This paper describes how dehumidification impedes the corrosion of steel and inhibits flash rusting, how to use dehumidification, and the impact of dehumidification on coating work costs.
