Caustic Soda Sodium hydroxide is utilized to raise the pH of water in a variety of applications. The chemical leaves no residual color, is a high-strength product, and is available at concentrations of 2-50%.
White crystalline solid Caustic soda, being highly hygroscopic and soluble in the water, should be stored in airtight containers or drums. During the dosing process, caustic soda is exposed to high moisture environment and adsorbs moisture until it liquefies. The mixture of liquefied soda and solid soda will cause difficulty in the dosing process.
Relative humidity in the dosing room should be maintained as low as possible, proposed to maintain at 20 ± 5% at 28°C (82°F) to overcome the problem of moisture pickup or moisture regain.
Due to powdering environment in the the dosing room, 100% fresh air system was proposed. Hence a Dehumidifier consisting of pre-cooled and after cooled is suggested.
The powder coated, CNC fabricated compact desiccant dehumidifiers (FFB series 170-4500 CMH) are lightweight and can be installed above the false ceiling.
For complete air handling and environment control needs (ranging from 2,500 CMH to 25,000 CMH)
