HTX Digital is a proactive digital heat exchanger management service focused on improving heat exchanger efficiency and reducing carbon emissions. This is achieved by remotely monitoring heat exchangers using existing sensor data. Glacier Energy's subject matter experts provided key insights into the failure modes of heat exchangers over a long period and developed tools to analyse and identify these failures early leading to optimal performance and reduced maintenance burden.
The calculations in the tool are based on industry standards by Tema and ASME and look at key failure mechanisms:
- Tube Vibration
- Tube Expansion
- Fouling
- Velocity Limits
- Cyclic loading
- Energy Efficiency
- Pressure and Temperature limits
By understanding the condition of your equipment, we can help reduce Opex savings by up to 30% due to smart cleaning and maintenance. We can help reduce carbon footprint through the same mechanisms and by understanding the potential failure mechanisms we can help with planning repairs at the optimal time for operations.
