Demaco Phase Separator
Demaco Phase Separator
For the proper functioning of most cryogenic applications, it is necessary that the system’s working pressure is adjustable and that the gas’s quality is continuously enhanced. To meet these two conditions, it is recommended to use a phase separator.
The Demaco phase separator:
How does a phase separator work?
The phase separator contains an internal storage dewar (the buffer), in which liquid gas is temporarily brought to a standstill. Because gas is lighter than liquid, any gas bubbles naturally rise at a standstill (or at very low flow rates).
At a preset pressure level, a relief valve opens at the dewar’s top, releasing the gaseous portion. At the bottom of the dewar, the pure liquid gas can then be extracted at an output pressure set by the customer.
The correct control of the filling valve is essential for the phase separator to operate correctly and open at precisely the right moment. The phase separator has a level sensor and a level controller, which control the filling valve.
Specifications
The construction and size of Demaco’s phase separators are always perfectly matched to any project at hand. This is achieved by using standard modules that are configured in a product configurator.
In recent years we mainly supplied phase separators with a capacity of 40 or 100 liters. In most cases, these sizes perfectly meet the requirements of our customers. If so required, we can develop phase separators to specific customer requirements.

Application of the phase separator
The phase separator guarantees pure liquid gases; for this reason, it is used across a wide range of industries. For most users of cold liquid gases, it is essential that the gas is pure, of high quality, and free from any gas bubbles.
Some of the industries in which we often see the phase separator are the medical industry, the food industry, the automotive industry, and the electronics industry. These industries all make extensive use of nitrogen systems, in which temperature and pressure control, as well as an excellent quality liquid gas, are essential for proper operation.
