Dosing station JW series

Overview
Shenzhen Jewellok Technology Co., Ltd. offers automated ultra-high-purity chemical handling solutions including the Chemical Delivery Module (CDM) and Chemical Delivery System (CDS). The CDS automates bulk transfer from storage to facility using electropolished 316L piping; the CDM provides point-of-use blending, dilution and precise metering. Both systems include automated leak detection and non-contact level monitoring to maintain safety and process purity.
