Benefits of Installing Expel for Gas Analysers
Expel transforms the operational efficiency of gas analysers by guaranteeing the continual removal of 99.999% of liquid water, oil emulsion fluids and solid particulates to 1 micron. What benefits does this result in for gas analysers?
Minimises the Risk of Fines and False Readings
Oil consists of hydrocarbons (HCs), and many gas analysers detect HCs. Therefore, failing to remove oil emulsion fluids will add more HCs to the sample, invalidating the results. As a result, companies can pay higher than necessary environmental taxes (such as carbon tax) or falsely appear to be breaching environmental laws, which can lead to heavy fines and legal consequences.
Stops Sensor Damage
Liquid water and particulate matter in the compressed air can cause physical damage to a gas analyser. These contaminants will corrode the gas analyser internally and destroy the capillary in the detector. Consequently, the analyser will need replacing.
Enhances Safety
In some applications, gas analysers are critical for site safety. They are often used to monitor the levels of toxic gases. Poor compressed air preparation can lead to inadequate safety measures and invalid readings.
Prolongs the Life of Molecular Sieves
Some industries (e.g., petrochemical, pharmaceutical, and natural gas processors) require compressed air to pass through a molecular sieve before reaching the gas analyser. Expel is the ultimate pretreatment to remove the bulk of three primary sources of compressed air contamination. Therefore, the molecular sieve’s adoption capacity can remain optimal for longer.
Stops Calibration Drift
Regular calibration is essential for maintaining accurate measurements taken by gas analysers. Compressed air contamination can compromise the stability of the calibration settings.
Reduces Downtime
If emission monitors are inoperable because of contamination issues, the site can only function once the gas analyser/s can provide accurate readings.
Optimises Performance
Contaminants can coat or block the gas analyser’s sensors, reducing sensitivity to the target gases. Therefore, the monitor’s ability to detect subtle changes or low concentrations in gas levels is compromised.

MRU Instruments HIGHLY recommends Expel!
MRU Instruments is renowned for producing an impressive range of gas analyser technology and emission-monitoring products. They serve various industries, including cement, glass, iron, steel, power plants, refineries, breweries, and more. After seeing the unrivalled protection that Expel provides gas analysers, the President of US Operations, Alex Kinderknecht, wanted to offer the best possible protection for the products they supply to companies.
“The SWG100 Biogas Analyser from MRU Instruments benefits significantly from integrating the Expel 3 unit, designed for advanced moisture control and flood protection. The Expel 3 efficiently removes liquid water, ensuring condensation does not reach the analyser, thus guaranteeing accurate gas measurements and extending the device’s lifespan. Its flood protection feature is also crucial for safeguarding the SWG100 Biogas Analyser against damage, maintaining its operational reliability in demanding environments.”

Case Study Example: Cement Plant
Expel saves a cement plant £30,000 in its first year of installation!
Before installing Expel, a cement plant had to spend £30,000 repairing a gas analyser because of compressed air contamination. Thanks to Expel, the site has successfully eliminated this expense and has not experienced any issues with air contamination since!
| Gas analyser repair | £30,000 |
| Number replaced annually | 1 |
| Total annual cost-saving | £30,000 |
