FAQ

Dew point is defined as the temperature at which air that contains water vapor begins to condense. The term is often used as an indicator of the degree of dryness of a wet gas. The lower the dew point, the less water vapor is included, which means a higher degree of dryness.

The following methods can be used with sunsep™ modules to reduce dew point:

• Lower the temperature of the supply gas at the inlet (Reduce the load of water vapor on the module)
• Increase the pressure of the supply gas
• Lower the flow rate of the supply gas
• Decrease the product dry gas flow rate
• Increase the purge flow rate (if applicable)

Send your flow (L/min), pressure (psig), inlet temperature, target atmospheric dew point, and fitting preferences. We’ll recommend the appropriate series and length.

Purge is application-dependent. Many systems operate efficiently in the ~10–20% range of the supply flow. We’ll confirm the right setting for your target dew point.

Pressure drop increases with flow and length. If pressure drop is a major concern, select the smallest length that achieves your dew-point target and keep fittings sized appropriately. We’ll help you evaluate drop during selection. Some of our products include a pressure drop table on the product page.

Our hollow fiber membranes move moisture toward the dryer of the gasses flowing on the inside and outside of the membrane. For example, if dry gas is supplied to the inside of the hollow fiber membrane, and wet gas or water is supplied to the outside, the dry gas on the inside of the membrane will be humidified.

In addition, the materials used in our hollow fiber membranes are highly selective for water vapor. Since permeation of gas components other than water vapor is extremely low, it is possible to humidify even when different gasses flow on either side of the membrane with virtually no impact on the composition of either gas. This illustrates how our membranes can be used as clean humidifiers.
