ZEDO ZS-120Z Industrial Ultrasonic Humidifier for Textile Dyeing and Finishing Facilities

Overview

The ZEDO ZS-120Z Industrial Ultrasonic Humidifier is engineered specifically for humidity-critical environments in textile dyeing and finishing plants—particularly during high-temperature drying, stentering, and heat-setting operations where precise moisture management directly impacts fiber integrity, dimensional stability, and final fabric quality. Unlike conventional evaporative or steam-based humidification systems, the ZS-120Z employs high-frequency ultrasonic oscillation (1.7 MHz) to atomize deionized or softened water into sub-5 µm droplets, enabling rapid, uniform dispersion without thermal load or mineral carryover. This principle ensures stable relative humidity (RH) control within ±2% RH across dynamic production zones—critical for preventing hydrolytic degradation of cellulose fibers (e.g., cotton), oxidative embrittlement during peroxide bleaching, and static-induced yarn breakage in high-speed weaving prep areas.

Key Features

• Full 304 Stainless Steel Construction: Seamless welded enclosure with electrophoretic powder coating resists corrosion from alkaline mordants, acidic rinses, and ambient textile processing vapors; includes automatic float-controlled water inlet and overflow safety cutoff.
• Integrated Ultrasonic Transducer Module: Patented ceramic transducer array with self-diagnostic dry-run protection eliminates mechanical wear, noise, and nozzle clogging—ensuring >99.5% operational uptime over 3,000–5,000 hours of continuous duty.
• IP68-Sealed Variable-Frequency Power System: Fully encapsulated in epoxy resin, rated for submersion at 1 m depth; delivers stable 1.7 MHz output under fluctuating grid voltage (±15%), reducing energy consumption by up to 40% versus fixed-frequency equivalents.
• High-Performance IP68 Waterproof Blower: 36V DC brushless motor with sealed ball bearings provides laminar airflow (≥120 m³/h) with <35 dB(A) acoustic emission—optimized for ductless localized humidification near stenters or open-width dryers.
• Alumina Ceramic Fogging Discs: Engineered for sustained operation in hard water (up to 300 ppm CaCO₃) and pH 3–11 chemical environments; compatible with inline water softening or reverse osmosis pretreatment systems.
• Microprocessor-Based Control Interface: Touch-sensitive HMI with real-time RH feedback loop, programmable setpoint ramping (0.1–5% RH/min), data logging (72-h buffer), and optional Modbus RTU/RS485 integration for SCADA-level process synchronization.

Sample Compatibility & Compliance

The ZS-120Z is validated for use in ISO Class 8 cleanroom-adjacent textile finishing bays and meets key regulatory prerequisites for industrial hygiene and process validation: CE marking per EN 61000-6-3 (EMC) and EN 61000-6-2 (immunity); RoHS 2011/65/EU compliance for restricted substances; and conformity with OSHA 1910.1200 (Hazard Communication) for safe handling of humidified air in mixed chemical exposure zones. While not a medical device, its humidity stabilization function supports adherence to AATCC Test Method 185 (fabric moisture regain), ASTM D1776 (conditioning textiles prior to testing), and ISO 139 (standard atmospheres for textile testing). For GMP-aligned facilities, optional audit-trail firmware enables 21 CFR Part 11–compliant electronic records (user login, parameter change logs, calibration history).

Software & Data Management

The embedded controller supports local standalone operation via front-panel interface or remote supervision through ZEDO’s proprietary Z-Link™ software (Windows/Linux compatible). Key capabilities include: real-time RH trend visualization with configurable alarm thresholds (visual + relay output); CSV export of time-stamped humidity/temperature logs; password-protected parameter locking for QA/QC enforcement; and firmware update via USB or Ethernet. Optional IoT gateway modules enable MQTT-based cloud telemetry for predictive maintenance analytics—monitoring transducer impedance drift, fan current draw, and water conductivity trends to preemptively schedule ceramic disc replacement or descaling cycles.

Applications

• Stenter frame humidity stabilization (target: 65–75% RH) to minimize warp/knit distortion during thermofixation of polyester blends
• Pre-drying chamber conditioning (target: 55–60% RH) to reduce static charge accumulation on synthetic filament yarns
• Post-bleach acid wash zones (pH 4.5–5.5) where low RH accelerates residual acid fixation and fiber hydrolysis
• Continuous dye range entry points to prevent premature dye migration due to rapid surface evaporation
• Warehousing of finished fabrics (target: 60–65% RH) to inhibit microbial growth and yellowing of cellulosics

FAQ

What water quality is required for optimal performance?

Deionized (DI) water with conductivity 150 ppm) requires inline RO pretreatment.

Can the unit operate continuously in high-temperature environments (e.g., near stenter ovens)?

Yes—the stainless steel housing and IP68-rated components are rated for ambient temperatures up to 50°C. Mounting distance from radiant heat sources should exceed 1.5 m; optional external cooling shroud available upon request.

How does the system integrate with existing plant BMS or PLC networks?

Standard RS485 Modbus RTU protocol allows direct connection to Siemens Desigo, Honeywell Experion, or Allen-Bradley ControlLogix platforms. Analog 4–20 mA RH output and digital dry-contact alarms are also provided.

Is routine maintenance required beyond ceramic disc replacement?

Annual inspection of fan bearings, power module seals, and sensor calibration is advised. No lubrication or filter changes are needed—consistent with ISO 55001 asset management principles for low-intervention industrial equipment.

Does ZEDO provide validation documentation for pharmaceutical or regulated textile applications?

Factory-issued IQ/OQ protocols (including sensor calibration certificates traceable to NIST standards) and FAT/SAT checklists are available under NDA. Installation qualification templates align with ISO 9001:2015 Clause 7.1.5.
