About Us

Founded in Singapore in 1998, Acesian Partners Limited (“Acesian”, formerly known as Linair Technologies Limited) is a multi-disciplinary group providing one-stop environmental solutions and integrated services to diverse industries including semiconductor, wastewater treatment, chemical, pharmaceutical and biotechnological industries. Acesian is also a leading building services and engineering solutions provider which specialises in the design, installation, testing and commissioning of Air-Conditioning and Mechanical Ventilation (ACMV) and Electrical Systems, additions and alternations to existing facility, consultancy services for the construction of semiconductor clean rooms and laboratories, and consultancy services on Information Communication Technologies. The Company was successfully listed in the SGX Sesdaq (now known as Catalist) on February 2005.

The ACESIAN Group has three major pillars:


Acesian has established a strong position in the duct manufacturing industry. Our manufacturing capability encompasses Ethylene Tetrafluoroethylene (ETFE) coated stainless steel ducts, uncoated stainless steel ducts, galvanised ducts and other specialised exhaust system components.

Acesian’s competitive advantage is our FM-approved status (an international commercial and industrial property insurance and risk management organisation) for production of ETFE-coated ducts. Our FM approved ETFE coated ducts, marketed under the brand name of CMT™ are highly corrosion resistant and designed to handle both flammable and non-flammable corrosive/ toxic fumes in exhaust systems.

Our high quality galvanised and stainless steel ductwork and accessories are suitable for less corrosive applications such as heating, ventilation and air-conditioning systems for commercial and industrial buildings.

Acesian’s line of products are widely used in biotechnology, pharmaceutical and waste water treatment facilities. Besides ducts, acesian also manufactures laboratory air flow products. Our Isolation Dampers are designed for effective shut-off and isolation of one or more tiers of filters in hazardous containment exhaust systems. In bio-hazardous environments, the dampers enable air filtration systems to be shut off for decontamination, or for filter changes. Our Ecoflow Venturi fast response variable air volume box offers solutions for critical airflow application in laboratories which require proper directional airflow.


This segment refers to the sale and distribution of products which are mainly used in industrial, biotechnology and pharmaceutical industries. These include critical airflow control systems and ductworks for laboratories.
