Didion - Model DST -Horizontal Flow Steam Separators

The advantage of the type DST Model is that it can handle larger liquid loads. For example, the standard DST models can manage a flow of 40% liquid by weight of the unit’s flow capacity. And, custom units can be designed to handle much more than that. This liquid removal capacity is much higher than our type DSL Model separator when operated in the horizontal flow configuration.

Well, it depends on your needs. Often, customers choose type DST air, steam, or moisture separators, even when the liquid load is very low. This preference is because during start-ups or shut-downs large liquid loads are present. Or, they might expect to get a stray slug of water or oil through the line. Therefore, the DST Model can handle all cases for a horizontal flow. Keep in mind the standard type DSL and DSU models can also take large liquid loads, but only in vertical up or down flows.

The type DST Models are slightly more expensive than the DSL Models. So, if you have a very small percentage of liquid in your flow, and you never expect to see much, then the type DSL model might be a better choice. Either way, we have you covered. Please contact us to select the right model and size for your application. If needed, we will custom design a unit for your needs. We are eager to be your separator supplier!
