Overview
The SZ-96A Automatic Water Distillation Unit is a benchtop, electrically heated, single-stage vapor-condensation system engineered for continuous production of high-purity Type III water in academic, industrial, and quality control laboratories. It operates on the principle of thermal phase separation: feed water is boiled under controlled heating, steam is generated, then condensed in a cooled stainless-steel condenser coil, and collected as purified distillate. The unit integrates passive thermal insulation and an automatic level-sensing fill mechanism to maintain consistent boiler volume, minimizing energy consumption and eliminating manual refilling during operation. Designed for unattended 8–12 hour batch cycles, it delivers reproducible conductivity ≤ 5 µS/cm (typical), meeting ASTM D1193-20 Grade III specifications for laboratory reagent water. Its compact footprint (W×D×H ≈ 320 × 300 × 650 mm) and front-access service panel support integration into ISO 17025-compliant lab workflows requiring traceable, low-maintenance water purification.
Key Features
- Integrated thermal insulation jacket reducing surface temperature and standby power loss by up to 35% versus non-insulated models
- Automatic water-level control with float-switch feedback loop ensuring stable boiling dynamics and preventing dry-heating failure
- Stainless steel 304 boiler and condenser assembly—resistant to scaling, corrosion, and thermal fatigue under repeated thermal cycling
- Over-temperature cutoff and ground-fault circuit interrupter (GFCI) protection compliant with IEC 61010-1 safety standards
- Front-mounted drain valve and removable condenser cap for routine descaling and cleaning without disassembly
- No external cooling water required—air-cooled condenser design eliminates dependency on municipal water lines or recirculating chillers
Sample Compatibility & Compliance
The SZ-96A accepts tap water, deionized water, or pre-filtered municipal supply as feedstock. It is not intended for seawater, high-TDS brines (>500 ppm), or chemically contaminated source water. Output purity conforms to ASTM D1193-20 Type III water requirements for conductivity, total oxidizable carbon (TOC), and silica content when operated with clean feed and maintained per manufacturer schedule. The unit’s electrical architecture meets CE marking criteria (EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU). Documentation includes factory calibration records, material certificates for wetted parts (SS304), and conformity declarations—supporting GLP audit readiness and internal SOP validation.
Software & Data Management
The SZ-96A is a standalone analog-controlled instrument with no embedded microprocessor or digital interface. Operational parameters—including heating status, water level, and thermal cutoff activation—are indicated via LED status lights and mechanical bimetallic thermostats. No software installation, firmware updates, or data logging capability is provided. All operational logs (e.g., run duration, maintenance dates, descaling intervals) must be manually recorded in lab notebooks or LIMS-compatible spreadsheets. This architecture ensures deterministic behavior, eliminates cybersecurity risks associated with connected devices, and aligns with FDA 21 CFR Part 11 Annex 11 principles for systems where electronic records are not generated.
Applications
- Preparation of rinse water for glassware cleaning in analytical chemistry labs
- Feedstock for autoclave reservoirs and humidification systems in microbiology suites
- Solvent preparation for non-critical HPLC mobile phases and buffer dilutions
- Calibration standard matrix for conductivity meters and pH electrodes
- Water supply for histology tissue processors and embedding stations
- Supporting ISO/IEC 17025 Clause 6.4.4 requirements for equipment used in test method validation
FAQ
What feed water quality is recommended for optimal distillate output?
Tap water with total dissolved solids (TDS) below 300 ppm and free chlorine < 2 mg/L is preferred. Pre-filtration through activated carbon and sediment filters is strongly advised to extend boiler service life.
How often should the boiler be descaled?
Frequency depends on feed water hardness; typically every 2–4 weeks under continuous use. Visual inspection for scale buildup on the heating element is the primary maintenance indicator.
Can the SZ-96A be integrated into a central purified water distribution system?
No—it is a point-of-use device with gravity-fed collection only. It lacks pressure-rated outlet fittings, flow sensors, or pump interfaces required for manifold integration.
Is the unit suitable for GMP-regulated pharmaceutical manufacturing?
It may serve as a secondary water source for non-sterile ancillary processes, but does not meet USP Purified Water monograph requirements for microbial limits or endotoxin testing without additional post-distillation treatment and monitoring.
What documentation is supplied with shipment?
User manual (English), electrical safety certificate, SS304 material compliance sheet, and factory performance test report showing initial conductivity and yield rate at 20°C ambient.
