  • What is passive 2-phase immersion cooling (aka open bath immersion cooling)?

    In this simple concept, hardware is immersed in a nonflammable dielectric liquid that boils on the heat generating electronics. Because the enclosures are not hermetically sealed and they are not under pressure (just like a freezer, the lid is simply closed when access is not needed), it's also called open bath immersion cooling.

    If it sounds a little radical, know that the boiling point is very low (ie. 34°, 49°C, depending on fluid) and that passive 2-phase (evaporative) immersion cooling has been around for decades to cool high value electronics in tens of thousands of systems including super computers, industrial applications and radar or microwave relays. The key difference is that all these systems are sealed and under pressure.

    Passive 2-phase immersion cooling (also known as open bath immersion cooling) eliminates all these complexities and makes the system very practical.

Global Projects

Hong Kong is one of the fastest-paced cities in the world. It has remained the world's freest economy since 1995, with low tax, no import and export restrictions, free trade and travel. Being located in the financial powerhouse and tech hub of Asia, we are well equipped to work on global projects. No matter how big, or small.

Hot & Humid

Most would consider Hong Kong's cramped living conditions, sky high property prices, and hazy skies as very challenging. When it comes to data centers, hot and humid climates are one of the biggest problems too. Hong Kong's power hungry infrastructure is a major disaster for the people's wallet and the environment. On the bright side, it's habitats like this that push companies to go the extra mile and make a change.
