Bangladesh Industrial Dehumidification Project
Engineering Project Case
Project OverviewProject Location: Bangladesh
Application: Industrial Factory HVAC & Dehumidification System
System Type: Rotary Desiccant Dehumidification Air Handling Unit (AHU)
Cooling Source: Chilled Water
Air Filtration: Multi-stage Filtration
Purpose:
Provide precise temperature and humidity control for industrial production while improving indoor air quality and ensuring stable manufacturing conditions.
Project Requirements
Based on the customer's required airflow, humidity control, filtration efficiency, and chilled water cooling conditions, YUJU designed a customized rotary desiccant air handling unit solution specifically engineered for Bangladesh's tropical climate.
Because Bangladesh experiences high temperature and high humidity throughout most of the year, a conventional chilled water air handling unit alone could not meet the required humidity level. A rotary desiccant dehumidification solution was selected.
