ZEDO ZS-F60Z Split-Type Ultrasonic Humidifier

Overview

The ZEDO ZS-F60Z Split-Type Ultrasonic Humidifier is an industrial-grade, precision-engineered humidity control system designed for stable, uniform, and contamination-minimized humidification in controlled laboratory, cleanroom, and high-value manufacturing environments. Unlike conventional steam or evaporative systems, the ZS-F60Z employs high-frequency ultrasonic transduction (1.7 MHz) to atomize deionized or softened water into sub-5 µm droplets—enabling rapid vapor-phase integration without thermal input, mineral dispersion, or condensation risk. Its split architecture physically isolates the ultrasonic oscillator module from the air distribution unit, reducing mechanical vibration transmission, simplifying maintenance access, and supporting flexible ducted or free-blow installation in spatially constrained or vibration-sensitive facilities. The system operates within a relative humidity setpoint range of 35–95% RH with ±3% RH repeatability under steady-state conditions, making it suitable for humidity-critical processes including pharmaceutical lyophilization support, semiconductor wafer handling pre-conditioning, and polymer film curing.

Key Features

• Full stainless-steel (AISI 304) enclosure and internal tank construction, electropolished and passivated for corrosion resistance and compliance with ISO 14644-1 Class 5–8 cleanroom compatibility requirements.
• Integrated ultrasonic transducer array with alumina ceramic diaphragms rated for ≥3,000 hours service life under hard-water conditions (up to 300 ppm CaCO₃ equivalent); self-diagnostic dry-run protection prevents cavitation damage.
• IP68-rated sealed variable-frequency power supply and 36 V DC waterproof bearing fan—submersible up to 1 m depth, eliminating moisture ingress failure modes common in humidification cabinets.
• Microprocessor-based controller with real-time hygrometric feedback loop, featuring a calibrated Shinyo HS-100 series capacitive humidity sensor (accuracy: ±2% RH, 10–90% RH, 23 °C).
• Modular mist delivery: triple-tube nozzle configuration enables directional saturation control, adjustable airflow velocity (0.8–2.4 m/s), and seamless integration with HVAC ductwork via optional static pressure compensation interface.
• Auto-fill system with float-level cutoff and overflow safety shutoff; integrated drain valve and sediment trap for routine water quality management per ASTM D1193 Type II specifications.

Sample Compatibility & Compliance

The ZS-F60Z is engineered for use with purified water sources meeting USP Purified Water or ASTM D1193 Type II standards. It does not generate aerosolized particulates above ISO 14644-1 Class 5 thresholds when operated with filtered feedwater and maintained per manufacturer-recommended intervals (filter replacement every 3 months; ceramic transducer cleaning every 6 months). The unit complies with electromagnetic compatibility (EMC) requirements per EN 61000-6-3 and low-voltage directive 2014/35/EU. While not intrinsically rated for hazardous locations, its non-sparking design and grounded stainless chassis support deployment in non-classified industrial laboratories operating under GLP and ISO/IEC 17025 environmental monitoring frameworks. Optional data logging modules support 21 CFR Part 11-compliant audit trails when paired with validated third-party SCADA platforms.

Software & Data Management

The embedded controller supports RS-485 Modbus RTU communication protocol for integration into facility-wide Building Management Systems (BMS) or LIMS environments. Local HMI features a 4.3-inch TFT touchscreen with multilingual UI (English, German, Japanese), configurable alarm thresholds (high/low RH, low water, transducer fault), and event-driven log storage (≥10,000 entries with timestamp and parameter snapshot). Remote monitoring is achievable via optional Ethernet/Wi-Fi gateway (not included), enabling secure HTTPS-based access to real-time RH trend charts, historical setpoint deviation analysis, and predictive maintenance alerts based on cumulative operating hours and voltage drift metrics. All configuration changes are logged with user ID and timestamp, satisfying basic ALCOA+ data integrity principles for non-GMP laboratory applications.

Applications

• Environmental stabilization in analytical instrument rooms (e.g., FTIR, XRD, SEM sample prep zones) where static charge accumulation compromises measurement reproducibility.
• Humidity buffering during stability testing per ICH Q1A(R2), particularly for hygroscopic APIs requiring controlled 40 °C / 75% RH chambers.
• Process air conditioning for textile, paper, and wood composite manufacturing labs where dimensional stability testing demands strict RH tolerance (±2.5% RH).
• Support humidification for electrostatic discharge (ESD)-sensitive electronics assembly validation environments aligned with ANSI/ESD S20.20.
• Supplemental moisture control in biosafety level 2 (BSL-2) containment labs where steam-based systems pose sterilization interference risks.

FAQ

What water quality is required for optimal operation?
Deionized or softened water with total dissolved solids (TDS) < 50 ppm is strongly recommended. Tap water may be used only if pre-filtered through a 5 µm sediment filter and scale-inhibiting cartridge; untreated hard water will reduce transducer lifespan and increase maintenance frequency.
Can this unit be integrated into an existing HVAC duct system?
Yes—the ZS-F60Z supports duct-mounted configuration via optional flanged inlet/outlet adapters (DN160–DN200). Static pressure compensation must be verified during commissioning to ensure consistent mist dispersion across variable airflow rates (200–1200 m³/h).
Is remote firmware update supported?
Firmware updates require local USB connection using ZEDO’s proprietary configuration utility; over-the-air (OTA) updates are not implemented due to security constraints in regulated lab environments.
Does the unit include calibration documentation traceable to NIST standards?
The factory-installed Shinyo hygrometer is supplied with a certificate of conformance (CoC), but NIST-traceable calibration is available as an optional service at time of order or during annual preventive maintenance.
What is the expected service interval for ceramic transducers under continuous operation?
At 24/7 duty cycle with ASTM D1193 Type II water, mean time between failures (MTBF) exceeds 4,200 hours; scheduled replacement is advised at 3,500 hours to maintain ±3% RH control fidelity.
