Engineered to meet stringent ISO standards and CE requirements for high-tech industrial environments.
Kuala Lumpur and the surrounding Klang Valley region have rapidly transformed into a primary hub for advanced manufacturing in Southeast Asia. Driven by Malaysia’s National Semiconductor Strategy and the expansion of biomedical research corridors in Selangor, local industries require highly sophisticated cleanroom solutions. A critical aspect of maintaining these controlled environments is precise humidity management.
In tropical climates like Kuala Lumpur, ambient outdoor humidity is consistently high, yet the air conditioning and purification processes within cleanrooms often strip moisture, leading to excessively dry conditions. Without high-precision, CE Certified Cleanroom Humidifiers, cleanrooms face severe threats from Electrostatic Discharge (ESD), structural micro-cracking in delicate substrates, and compromised chemical reactions.
The demand for high-end cleanroom humidification systems in KL is propelled by the rapid scale-up of OSAT (Outsourced Semiconductor Assembly and Test) facilities, biopharmaceutical vaccine production plants, and advanced medical device manufacturers. Compliance with international standards such as ISO 14644 and CE certification has become a non-negotiable prerequisite for local enterprises looking to integrate into global supply chains.

Established in 2019, Zhejiang Ailv Purification Technology Co., Ltd. is K-STONE’s dedicated manufacturing arm, located in Meixi Industrial Park, Anji, Zhejiang Province. The facility spans 30 acres with a self-built factory of approximately 30,000 square meters.
The factory is equipped with state-of-the-art production lines and testing equipment, enabling high-precision manufacturing of cleanroom components including:
Our products are widely applied in biomedical, food processing, electronics, semiconductors, new energy, and medical aesthetics industries. By integrating design, production, and quality control, we ensure high-performance, reliable cleanroom solutions for global customers.




Different high-tech operations in Kuala Lumpur require specific relative humidity (RH) thresholds to secure productivity, product quality, and safety. Here are the primary localized application scenarios.
In semiconductor fabrication plants, maintaining RH between 45% and 55% is crucial. Under-humidified environments generate static charge, attracting airborne particles to the wafers (ESD damage). Over-humidified environments cause photoresist adhesion failure. CE certified ultrasonic and steam humidifiers provide the rapid, clean response needed to keep wafer yields at maximum efficiency.
Pharmaceutical facilities must operate under strict GMP guidelines. Cleanroom humidifiers integrated into these environments must use pure steam to prevent microbiological growth. Precise relative humidity prevents the evaporation of liquid medicines during critical fill-finish processes, protecting batch consistency and ensuring compliance with local National Pharmaceutical Regulatory Agency (NPRA) standards.
High-end medical devices, particularly those with sensitive electronic components or biological coatings, require strict environmental controls during packaging. Humidification prevents electrostatic charge buildup that could compromise sterile packaging seals or damage delicate diagnostic sensors prior to shipment.
