ZEDO ZY-1800 Wall-Mounted Ultrasonic Air Deodorization & Disinfection System

Overview

The ZEDO ZY-1800 is a wall-mounted, microprocessor-controlled ultrasonic air treatment system engineered for continuous odor suppression, microbial reduction, and ambient humidification in high-traffic public sanitation facilities. Unlike passive masking agents or intermittent chemical spraying systems, the ZY-1800 operates on the principle of controlled aerosol dispersion: it converts liquid formulations—odor-neutralizing botanical concentrates, disinfectants, or potable water—into sub-10 µm droplets via high-frequency piezoelectric transduction. This ultrafine mist ensures prolonged airborne suspension, maximizing contact time between active ingredients and volatile organic compounds (VOCs), ammonia (NH₃), hydrogen sulfide (H₂S), and airborne microbes. Designed specifically for environments where hygiene compliance, low maintenance, and unattended operation are critical—including highway service areas, transit hubs, educational campuses, and tourist sites—the ZY-1800 integrates into existing facility management protocols without requiring structural modification or HVAC integration.

Key Features

• Stainless steel housing with electrophoretic powder coating for corrosion resistance and long-term durability in high-humidity, chemically aggressive restroom environments.
• Six integrated ultrasonic nebulizer transducers delivering uniform, stable mist output with particle size distribution consistently below 10 µm—optimized for diffusion efficiency and surface interaction.
• Digital programmable timer enabling precise duty-cycle configuration: spray duration, interval (1 second to 99 minutes 59 seconds), and daily activation windows can be set independently.
• 5.5-liter removable water reservoir with top-fill port and bottom drain valve for rapid refilling and cleaning; includes dry-run protection circuitry to prevent transducer damage during low-fluid conditions.
• Modular fluid compatibility: supports neutral pH odor-neutralizing concentrates (non-irritating, non-allergenic), EPA-registered disinfectants compliant with EN 14476 or ASTM E1053, and potable water for humidity control—no hardware modification required.
• Standardized Ø75 mm PVC conduit interface for centralized distribution across multi-stall layouts; validated effective delivery range up to 8 meters with minimal pressure loss.

Sample Compatibility & Compliance

The ZY-1800 does not perform analytical measurement but functions as an environmental conditioning device within regulated sanitation infrastructure. Its operational design aligns with WHO Guidelines on Sanitation and Health (2018), ISO 22196:2011 (antimicrobial activity of plastics), and national public health standards for non-residential restroom ventilation and disinfection frequency. When deployed with registered disinfectants, the system supports facility adherence to local health department requirements for routine surface and air decontamination. As a non-ozone-generating, non-UV-based solution, it avoids regulatory restrictions associated with ozone exposure limits (OSHA PEL: 0.1 ppm) or UV-C safety protocols. The stainless steel construction meets ASTM A240/A240M for corrosion resistance in chloride-rich indoor atmospheres.

Software & Data Management

The ZY-1800 employs embedded firmware with non-volatile memory for parameter retention during power interruption. While it lacks network connectivity or cloud telemetry, its time-programmable controller logs cumulative runtime hours and records last-activated timestamp—accessible via front-panel LED display. For institutional deployment, the device supports GLP-aligned maintenance tracking: refill intervals, concentrate batch numbers, and service dates can be manually logged against unit serial numbers. No data encryption or FDA 21 CFR Part 11 compliance is applicable, as the system generates no audit-trail-capable electronic records; however, its deterministic timing logic ensures reproducible dosing schedules suitable for internal QA documentation.

Applications

• Continuous odor abatement in enclosed restrooms where ammonia and mercaptan emissions exceed olfactory thresholds (≥5 ppm NH₃).
• Supplemental air disinfection in facilities lacking centralized HVAC UVGI or bipolar ionization—particularly during peak occupancy periods.
• Humidity stabilization in arid climates where low relative humidity (<30% RH) accelerates pathogen survival and exacerbates VOC volatility.
• Automated maintenance reduction in outsourced janitorial contracts: extends time between manual reapplication of sprays or incense-based masking agents from hours to weeks.
• Integration with building management systems (BMS) via optional dry-contact relay output (available on ZY-1800-R variant) for synchronized activation with occupancy sensors or lighting controls.

FAQ

Does the ZY-1800 generate ozone or emit UV radiation?

No. It utilizes only ultrasonic nebulization—no corona discharge, photolysis, or plasma generation occurs.

Can the unit be used with chlorine-based disinfectants?

Not recommended. Hypochlorite solutions may corrode stainless steel components and degrade piezoelectric transducers; only neutral-pH, non-oxidizing disinfectants are supported.

What is the expected service life of the nebulizer transducers?

Under normal operating conditions (≤8 hrs/day, distilled or softened water usage), transducer longevity exceeds 12,000 hours per IEC 60730-1 reliability testing.

Is calibration required?

No. The system has no adjustable sensors or feedback loops; performance consistency is maintained through fixed-frequency transduction and precision-machined fluid pathways.

How often must the reservoir be cleaned to prevent biofilm accumulation?

We recommend weekly descaling with 5% citric acid solution and rinsing with deionized water—especially when using hard tap water or concentrated additives.
