ENVIRONMENTAL TRIAXIAL TESTING SYSTEM

Product Code : ETTS

The Environmental Triaxial Testing System (ETTS) is a temperature controlled testing system for stress path testing. Key features include, Frozen Soil Testing, Gas Hydrate Testing, High Pressure Testing and High & Low Temperature Testing

The -200C cooling system provides ideal conditions for frozen soil testing. Its high pressure testing capability (up to 10MPa) along with low temperature provides the ideal environment for Gas Hydrate Testing. The system also has the option for a Heating only system.
 

Key features Benefits to the user
Heating & Cooling Options: 
-20oC  to +65oC
 
The cooling system uses a coiled tube section inside the cell, this is connected through the standard ports within the cell base to a glycol cooling unit allowing temperature transfer close to the specimen.
Optional Heating Only System:
Ambient to 60oC
Ambient to 100oC 		The heating system works using thermal pads attached to the outside of the triaxial cell then enclosed within an environmental chamber to retain the heat. There are up to 4 temperature sensors relaying back to the control box for enhanced temperature accuracy.
High Pressure (Up to 10MPa): High Pressure combined with low temperature make it ideal for Gas Hydrate testing.
Gas Hydrate Testing (Gaseous back pressures): The ETTS can be adapted for gaseous back pressures such as Air, Carbon Dioxide,  Nitrogen or Methane for Gas Hydrate testing.
Frozen Soil Testing: Cooling to -20oC provide ideal conditions for frozen soil testing.
