Whether it is for quality verification or system troubleshooting, we provide the complete range of compressed air testing to meet your requirements.
In a Good Manufacturing Practice (GMP) environment, it is a requirement to perform qualification of critical gasses. Clean Dry compressed air which may be used for direct product contact is thus require to be qualified on a regular basis to ensure that its quality requirements are still within specifications.
In industries like semiconductor and waffle fabrication, the dust and contaminant sensitive products makes it critical that compressed quality is constantly monitored. Spray painting factories and workshops which uses compressed air in their spray painting line must ensure moisture free compressed air as moisture will impact the quality of the spray painting works by creating uneven water dots on the painted surface.
In Pharmaceutical and Food Industries, the presence of harmful micro-organism, mold and fungus are undesirable and must be avoided at all cost. These will impact the quality and lifespan of the products. Thus the presence of oil, water and microorganism must be verified from time to time to ensure that the system and individual purifier or filter in place are properly working to eliminate these undesirables.
Humidity Measurement
Complying with ISO8573-3 requirement for measurement of humidity, our pressure dew point meter helps to measure dew point in compressed air systems or gas distribution networks.
By maintaining proper amount of moisture and humidity in your compressed air, the lifespan of the plant’s machinery, equipment and its components is prolonged. Less moisture in air also makes maintenance of the compressed air system more efficient and ensure stable and consistent quality of products.
Dry compressed air also minimizes corrosion and also con-tamination due to the presence of bio burden. This saves cost and quality in the long run. Our tester is portable making it easy to operate in tight spaces and comes complete with a built in printer which is able to present the raw data instantly. It is also equipped with a memory card which allows it to store test records.
Oil Vapour Measurement
We offer two superior methods for sampling oil vapour and aerosol for compressed air testing, which is in accordance to ISO8573-2 test methods for oil aerosol content.
METHOD 1: Our high surface area, low velocity ISO compliant methodology utilizing a glass fibre filter is recommended by the Compressed Gas Association (CGA) and the National Fire Protec-tion Association (NFPA). Our oil aerosol and particulate sampling equipment is capable of isokinetic sampling. The filter sample test is performed at the full flow rate of the air/gas supply simulating operational use. This helps ensure that the contaminants suspend-ed in the air/gas stream reach the sampling equipment.
The oil aerosol captured by the glass fibre filter will be analysed via Fourier Transform Infrared Spectroscopy (FTIR) to determine the actual concentration of oil present in your compressed air line. Our sampling and analysis method captures a truly representative sam-ple of the oil aerosol present in the air stream.
METHOD 2: This is a direct measurement and on the spot result using the most advance oil vapour detection sensor and electroni-cally calibrated device.
The device is highly portable and has a detection limit between 0.003 to 10.0 mg/m3 which is way below the required standard for most industries. This device is also able to electronically store the recorded data and has a built in printer to be able to print out raw results instantaneously.
Solid Particle Measurement
We utilize a modern laser particle counter which has been optimized to measure the amount of solid particles content in compressed air or compressed gases. It complies with ISO8573-4 requirement for measurement of solid particle content.
Our laser particle counter measures fine solid particles down to 0.1 micron and up to 5.0 micron, thus fulfil the requirement stipulated in the compressed air standard ISO8573-4 and also ISO14644 and ISO 14698 for clean-room classes.
This device is calibrated yearly and comes with certificate of calibration and the copy will be attached together with the test reports.
Microbial Content Measurement
Our microbiological slit sampler is capable of sampling the number of airborne particles carrying viable organisms. The sampler draws air through a slit at a fixed flow rate. The particles contained in the air are impinged upon an agar surface below the slit. The agar is contained in a specific culture plate size, recommended by ISO8573-7, test method for viable microbiological contaminant content. The plate is rotated by a synchronous drive motor. At conclusion of sampling the drive motor and gas supply shut off automatically. After sampling, the plate is incubated and the colonies are counted. Results are expressed as viable particles per unit of air. This device is calibrated yearly and comes with certificate of calibration and the copy will be attached together in the test reports.
Nitrogen Purity Measurement
Using our sophisticated oxygen & nitrogen analyzer; the purity of Nitrogen can be analyzed up to 99.999%.
Air Leak Detection
Leakage in pipelines cost a whole host of problems to a compressed air system. Pressure loss and insufficient supply to cope for the demand will be the first two obvious problems.
But the more costly indirect problems are those that are most worrying. Loss of air means loss of money because energy required to make up for the loss is very high. For every 1 bar pressure loss energy consumption goes up to as high as 8%. This also puts strain to the compressor which may have pre-mature failure and thus increasing the cost of maintenance.
Also water will be able to seep through the leaky pipes and water causes rust and other problems to the quality of the air and thus the products.
Our ultrasonic leak detection service helps to identify these leaks……Plug the leaks and save money!
Flow Measurements
Air flow measurement can be done using thermal mass flow meter or ultrasonic flow meter.
Air flow measurement is performed for a few reasons: –
- To verify compressor flow rate
- To verify losses from desiccant dryer and any relevant system
- To ascertain quantity of air or air consumption to certain equipment or certain point
- For Energy study
Our air flow meter has the capability to compensate temper-ature and pressure to provide actual flow measurements. It is also able to data log up to 1 month so that the trend of air consumption can be determined
Energy Study
Air is free but compressed air is not. It actually cost a lot of money to run a compressed air system. That is why doing an energy study on your compressor and compressed air system makes sense to optimize its usage and performance.
With this study we will be able to come up with recommendations for optimization and of course ultimately cost savings. Not to mention with monetary savings comes energy savings and thus it is also an environmentally friendly exercise.
With our energy monitor and data logging module, we will be able to chart the energy consumption and provide useful trends in the energy consumption.
