Most engineers rely on handheld gas 'sniffers' to detect leaks. While effective for confirming the presence of CO2, they often require time-consuming tracing when a leak is suspected in order to locate the exact source within complex pipework.
How it works
DTX Tape is applied once directly onto welds, joints, valves and other potential leak points during installation or maintenance. From that point onwards, it passively monitors each location continuously.
When CO2 comes into contact with the tape, it changes colour from purple to yellow, providing an immediate visual indication of the leak location. Once the gas is no longer present, the tape returns to its original colour, allowing ongoing inspection during maintenance visits.
This makes it particularly useful during commissioning, planned maintenance and fault-finding, where reducing downtime is critical.
Faster fault-finding
DTX Tape complements existing CO2 detection methods by helping identify very small or intermittent leaks that can be difficult to locate using handheld detectors, pressure testing or soap and water methods.
Leak detection in refrigeration and HVAC systems can take days or even weeks due to extensive pipe networks and confined plant areas. Once installed, engineers can visually inspect the system during routine visits, without needing to re-scan the pipework each time.
Refrigeration mechanic Aidan Lucey reported applying the tape to a problematic area during maintenance and returning weeks later to immediately spot the colour change, significantly reducing call-out time. In another case, Christopher Carelsen from Future Green Now noted that DTX Tape identified a leak so small it was barely detectable using a soap and water test.
A simple visual tool for faster maintenance
DTX Tape is most effective when applied proactively across a system, enabling engineers to track changes over time and quickly identify new leak activity at subsequent visits. This creates a clear visual reference of system integrity at key points.
By providing a localised, real-time visual leak indicator, DTX Tape supports earlier intervention, helping reduce energy loss and improve operational efficiency.
