Product Overview



The Vacuum Insulated Phase Separator, namely Vapor Vent, is one of the most common equipment of Vacuum Insulated Cryogenic Piping System. The phase separator is mainly to separate the gas from the cryogenic liquid, which can ensure,

1. Liquid supply volume and speed.
2. Incoming temperature of terminal equipment.
3. Pressure adjustment (reducing) and stability.

The Phase Separator is a mechanical structure and system that does not require pneumatic and electrical source, and mainly used for liquid nitrogen service. It is recommended to be placed at the highest point of the piping system to ensure maximum effect.


There are three type of separators to satisfy various demands,
1. HLSP1000 series, a common phase separator.
2. HLSR1000 series, a pressure step-down regulating phase separator and suitable for some special control requirements.
3. HLSC1000 series, a special phase separator uses for Molecular Beam Epitaxy (MBE) System.

This product link is for HLSR1000 Series, Links to the other two products can be found in the related products section of the page.

1. The phase separator is recommended to place in the main line of the VJ Piping System, which has better exhaust capacity than branch lines.
2. It has a large capacity and can act as a buffer tank, and better meet for the equipment which needs instantaneous large amount of liquid.
3. Compared with small volume, HL’s phase separator has better insulated effect and more rapid and sufficient exhaust effect.
4. Automatically, without power supply and manual control.
5. It can be customized according to the special requirements of users.
