Sizing an industrial dehumidifier involves establishing the project design conditions by answering questions and considering several factors: what is the best temperature and humidity for the application? After the design dry bulb temperature and humidity level has been established, check what the dew point is of these two conditions. What is the moisture load? After the worst case load is calculated the equipment is selected based on 100% of the calculated load or less. Other considerations include the size of the space, amount of outside air introduced, lowest temperature, existence of a vapor barrier and open liquid tanks. Desert Aire has developed a sizing tool that will calculate the moisture load of many industrial applications. The method used is based on the ACCA Manual N and ASHRAE formulas. Our Tech Bulletin 29 explains the information required and considerations for sizing an industrial dehumidifier.
