- EcoSys (Malaysia) Berhad is an industrial solutions provider and investment holding company that specializes in the design, development, precision manufacturing, and integration of ultra-high purity delivery systems and environmental abatement solutions for the pan-semiconductor and solar photovoltaic industries. The company operates through two primary core business segments: Ultra-High Purity Fabrication and Abatement Systems. Within its Ultra-High Purity Fabrication segment, the company provides precision-machined components and customized sub-assembly modules manufactured in certified cleanroom and non-cleanroom environments; gas delivery panels, valve manifold boxes, and fluid handling modules engineered to safely transport process gases and chemicals with zero micro-contamination; computer numerical control precision machining and specialized weldments for front-end semiconductor processing equipment; and surface treatment alongside helium leak-detection testing services. Within its Abatement Systems segment, the company manufactures and services point-of-use exhaust gas treatment equipment designed to capture, scrub, and neutralize hazardous, pyrophoric, corrosive, and greenhouse gas effluents generated during wafer fabrication and solar cell manufacturing; the Marathon series of integrated plasma-wet and burn-wet scrubbers engineered for destruction of perfluorocarbons; the Guardian series of thermal oxidizers and combustion burn boxes configured for flammable and pyrophoric gases; the CDO series of thermal-electric and wet abatement units designed for fluorine and chamber-cleaning exhaust treatment; the Vector series of wet scrubbing systems; and complete lifecycle services including engineering design, system customization, on-site installation, testing, commissioning, preventative maintenance, component overhaul, and spare parts supply. The company caters to global front-end semiconductor equipment manufacturers, integrated device manufacturers, pure-play wafer foundries, and solar photovoltaic module producers across Malaysia, Singapore, China, India, Taiwan, and the United States. Headquartered in Simpang Ampat, Penang, Malaysia, with roots dating back to 2005 through its operating entities, the company operates via key direct and indirect subsidiaries comprising SIW Manufacturing Sdn Bhd, EcoSys Pte Ltd, BHT Services Pte Ltd, and SIW Engineering Pte Ltd, alongside affiliated operations in China through Anhui EcoSys Automation Solutions Co. Ltd. and Anhui EcoSys Trading Co. Ltd. In recent developments, the group executed significant structural reorganizations and market expansions; originally incorporated as HT Advance Tech R&D Sdn Bhd in June 2023, it changed its name to EcoSys (Malaysia) Sdn Bhd in May 2024 before converting into a public limited company as EcoSys (Malaysia) Berhad in December 2025. In October 2026, the company completed its initial public offering on the ACE Market of Bursa Malaysia under the stock code 0477 and ticker ECOSYS, raising approximately RM39.34 million following an initial retail offering that was oversubscribed by more than 200 times. Capital raised from the public listing has been deployed to expand cleanroom fabrication capacity at its Penang facilities, acquire advanced precision machinery, fund operational working capital, and establish a dedicated sales and engineering service center in India to support growing regional foundry demand. In addition, clean energy specialist Solarvest Holdings Berhad acquired a strategic equity stake in the company to establish collaborative initiatives across the renewable energy and sustainable manufacturing technology sectors.
