Designing, Manufacturing, and Installation of APCS
Why Need Scrubber System?
The Scrubber system is essential for compliance with Malaysia’s Environmental Quality (Clean Air) Regulations, 2014, due to the country’s stringent enforcement of air quality standards.
These regulations aim to limit harmful emissions from industrial sources to protect public health and the environment. Scrubbers play a crucial role in this by effectively removing pollutants, such as sulfur dioxide, nitrogen oxides, and particulate matter, from industrial exhaust gases before they are released into the atmosphere.
With tightening enforcement and increasing penalties for non-compliance, implementing scrubber systems is necessary for industries to meet the required air quality standards and avoid legal and financial consequences.
Features & Benefits
In Greentech Alpha, we offer an air pollution control system. Our control system is installed accordingly to meet regulatory requirements. We have gained vast experience in the application of APCS in various industries. Not only that, we do offer a few other related air pollution control system solutions such as:
Scrubber System Cleaning & Maintenance
Scrubbers are air pollution control devices that use liquid to remove particulate matter or gases from an industrial exhaust or flue gas stream.

Inspection, Testing & Examination of Engineering Control Equipment
Local Exhaust Ventilation (LEV) systems and general exhaust ventilation systems are types of engineering control measures commonly used in the workplace to manage exposure to chemicals hazardous to health. These systems must be examined and tested for effectiveness and efficiency at intervals not exceeding twelve months by a hygiene technician registered with the Department of Occupational Safety and Health (DOSH), in accordance with the Occupational Safety and Health (Use and Standards of Exposure of Chemicals Hazardous to Health) Regulations 2000 (USECHH)
Chimney Emission & Ambient Air Monitoring Services – Ensuring Clean, Compliant Air
At Greentech Alpha, we specialize in providing reliable and accurate chimney (stack) emission monitoring and ambient air quality monitoring to help industries comply with the environmental standards set by the Department of Environment (DOE), Malaysia.
Our services are designed to ensure that emissions from industrial processes are within the permissible limits and do not pose a threat to public health or the environment.
Our Monitoring Services Include:
1. Stack (Chimney) Emission Monitoring
We conduct isokinetic sampling and analysis of pollutants released through chimneys or stacks, in accordance with Environmental Quality (Clean Air) Regulations 2014. Parameters typically monitored include:
- Particulate matter (PM)
- Sulfur dioxide (SO₂)
- Nitrogen oxides (NOx)
- Carbon monoxide (CO)
- Volatile organic compounds (VOCs)
- Heavy metals and acid gases (where applicable)
Our monitoring is performed using DOE-approved methodologies and calibrated instruments, ensuring accurate, compliant reporting.
2. Ambient Air Quality Monitoring
We measure the quality of air in and around your facility to assess environmental impact and ensure community safety. Common ambient parameters monitored:
- Total Suspended Particulates (TSP)
- PM10 & PM2.5
- Gaseous pollutants (SO₂, NO₂, O₃, CO)
- Odour and other site-specific contaminants
This helps to evaluate the environmental footprint of your operations and support any necessary corrective measures.
Why Fluke 922 is Important for Wet Scrubber Systems
The Fluke 922 ensures wet scrubbers run at peak efficiency by accurately measuring airflow, static and differential pressure in ducts and scrubber units. These readings are vital to:
Verify scrubber performance and compliance.
Detect blockages or fouling early.
Balance airflow for maximum efficiency.
Reduce energy costs from excessive pressure drop.
With the Fluke 922, operators gain reliable data to maintain cleaner emissions and lower operating costs.
