Hussmann’s TerraChill is a natural refrigerant solution that reduces the HFC charge and features a lower carbon footprint than traditional central direct expansion systems. TerraChill uses pumped liquid CO² as a secondary fluid in both low temperature and medium temperature applications.

•  Use of lower cost natural refrigerant.
•  Reduced HFC refrigerant charge (60-70%).
•  Reduced carbon footprint (30-50%).
•  Lower HFC refrigerant leak rate.
•  Smaller pipe sizes than centralized direct expansion systems.
