Solve your pharmaceutical water quality challenges with YohoAI's cGMP-compliant PW Series purified water systems. Dual-stage RO, conductivity <1.1 uS/cm, full IQ/OQ/PQ validation, and audit-ready documentation for FDA, EU, and international GMP facilities.
Meeting pharmaceutical GMP water quality standards is one of the most critical and challenging compliance requirements for any drug manufacturing facility. Water is used throughout pharmaceutical production-as a solvent, process medium, and cleaning agent-and every pharmacopeia authority (USP, EP, ChP) sets strict purity limits. YohoAI's PW Series Pharmaceutical Purified Water Systems are purpose-built to eliminate GMP water compliance pain points: inconsistent water quality, incomplete documentation, failed conductivity monitoring, and costly validation delays. From PW-500 lab-scale to PW-5000 industrial systems, every unit ships with complete IQ/OQ/PQ documentation, cGMP-compliant construction, and on-site validation support.
Verified factory data - not marketing estimates
Every PW Series system ships with a comprehensive validation dossier: User Requirement Specification (URS), Functional Design Specification (FDS), Design Qualification (DQ), IQ/OQ/PQ protocols, FAT/SAT reports, P&ID drawings, material traceability certificates (3.1/3.2), and risk assessment per ICH Q9. Documents are available in English and structured for direct integration into your site quality management system (QMS) for regulatory submissions.
Real-time online conductivity meters at each RO stage and product water outlet provide continuous water quality data with configurable alarm setpoints. Conductivity trend logs are automatically recorded by the PLC/HMI system, creating the audit-ready water quality release records required by USP <645> and EP Chapter 16 for pharmaceutical water systems.
YohoAI's dual-stage RO technology achieves conductivity below 1.1 uS/cm consistently-meeting and exceeding the pharmacopeia limit. Second-stage concentrate recycling maintains >=75% overall recovery without sacrificing purity. Optional EDI polishing can reduce conductivity to <0.1 uS/cm for injection pre-treatment or the most sensitive analytical applications.
The sanitary 316L stainless steel distribution loop supports Clean-in-Place (CIP) with chemical sanitization and Sanitization-in-Place (SIP) with hot water at 80 degC. Ozone residual in the circulation loop provides continuous low-level microbiological control between sanitization cycles. The system is designed to prevent dead legs and maintain continuous circulation to all use points.
The PLC + HMI system records all critical process parameters-conductivity, flow rate, pressure, temperature, ozone residual, and alarm events-with timestamps for full batch traceability. Data export functionality supports integration with site SCADA or ERP systems. Alarm history provides the deviation documentation needed for GMP investigations and CAPA records.
YohoAI engineers provide on-site IQ/OQ/PQ execution support during commissioning. Free operator training and preventive maintenance training are included with every system. For international clients, YohoAI provides documentation packages adapted to specific regulatory requirements (FDA, EMA, TGA, NMPA) and supports regulatory audit preparation.

The three most common GMP water system failures are: (1) Inconsistent water quality due to fouled RO membranes or inadequate pre-treatment-solved by YohoAI's multi-barrier pre-treatment train and automatic Fleck controls. (2) Incomplete documentation for regulatory audits-solved by YohoAI's turnkey IQ/OQ/PQ dossier and data logging. (3) Failed conductivity or endotoxin test results-solved by online monitoring with alarm setpoints and EDI polishing option for ultra-low conductivity.
GMP pharmaceutical water system validation requires: URS (User Requirement Specification), FDS (Functional Design Specification), DQ (Design Qualification), IQ (Installation Qualification), OQ (Operational Qualification), and PQ (Performance Qualification). YohoAI provides all documents as standard-IQ/OQ/PQ protocols, FAT/SAT reports, P&ID drawings, material certificates (3.1/3.2), and risk assessment per ICH Q9. PQ execution support is included on-site during commissioning.
USP <645> and EP Chapter 16 require conductivity testing at three stages: Stage 1 (online, continuous monitoring with alarm at 1.1 uS/cm), Stage 2 (offline lab measurement at 25 degC), and Stage 3 (reduced frequency ongoing monitoring). YohoAI's PW Series includes calibrated online conductivity meters at each monitoring point with automatic data logging, alarm configuration, and sample port access for offline Stage 2/3 testing. Calibration records are included in the documentation package.
System cost for a PW-500 (500 L/h) with standard IQ/OQ documentation ranges USD 15,000-50,000. A PW-2000 (2,000 L/h) GMP system with expanded validation and SCADA integration ranges USD 50,000-100,000. Large PW-5000 (5,000 L/h) turnkey projects range USD 80,000-200,000+. Beyond equipment, budget for on-site PQ execution support (YohoAI included), analytical testing costs (TOC, endotoxin, conductivity), and internal QA reviewer time for document review.
GMP guidelines (EU GMP Annex 1, FDA 21 CFR Part 211) require regular sanitization to control microbiological quality. Best practice is weekly ozone sanitization (if ozone is used), monthly hot water sanitization at 80 degC for 30-60 minutes, and quarterly comprehensive CIP of the RO membrane train. Microbiological Alert and Action Limits should be established based on your water quality data trend. YohoAI provides a sanitization SOP template and schedule as part of the validation package.
Pricing varies by configuration and accessories. Please send us your specific requirements including production capacity needs, tube/can/capsule format, and required certifications. We typically respond within 2 hours with CIF/CFR/FOB pricing.
Standard delivery ranges from 30-90 working days depending on the model and configuration. Pharmaceutical GMP configurations with validation documentation packages require additional 5-10 working days. Expedited manufacturing is available for urgent orders at a 15-25% premium.
All YohoAI machines carry CE certification and are designed to meet cGMP and ISO9001 standards. Additional certifications including FDA compliance and specific food-grade standards are available depending on the product line and configuration.
GMP-compliant installation begins with a comprehensive site assessment and water quality analysis conducted by YohoAI's engineering team. The system must be installed in a controlled environment with qualified utilities including 380V three-phase power, purified feed water, and a clean drain system. All wetted piping uses sanitary orbital-welded 316L SS with zero dead-leg design to prevent biofilm accumulation. The distribution loop must maintain continuous circulation to all use points. YohoAI provides P&ID drawings, installation supervision, and free on-site operator training as part of every GMP system delivery, ensuring full regulatory readiness from day one.
Ongoing GMP compliance depends on rigorous sanitization and monitoring protocols. Best practice is weekly ozone sanitization of the distribution loop, monthly hot water sanitization at 80 degC for 30-60 minutes, and quarterly comprehensive CIP of the RO membrane train. The PLC + HMI system continuously logs conductivity, flow rate, pressure, temperature, ozone residual, and alarm events with timestamps for batch traceability. Microbiological Alert and Action Limits should be established based on your water quality trend data. All sanitization cycles, filter replacements, and maintenance activities must be documented in the site quality management system for regulatory audit readiness.
The validation lifecycle extends beyond initial IQ/OQ/PQ execution. Annual requalification of critical instruments (conductivity meters, pressure transmitters, temperature sensors) is required per GMP guidelines. The online conductivity monitoring system supports USP and EP Chapter 16 three-stage conductivity testing requirements with calibrated meters, automatic data logging, and sample ports for offline Stage 2 and Stage 3 testing. YohoAI provides a sanitization SOP template, preventive maintenance schedule, and calibration records as part of the validation documentation package. For international clients, documentation is adapted to specific regulatory requirements including FDA, EMA, TGA, and NMPA submissions.
