Product Introduction
WN-1004A-5M | 50Hz Industrial High-Pressure Misting System
Native 50Hz / 230V Single-Phase Standard • High-Capacity Output • Adjustable Auto-Drain Relief • Extended Piping Ready
| 50Hz / 230V Global Grid Compliant |
Max. 65 Nozzles Rated Capacity (0.15mm) |
2–10s Adjustable Auto-Drain Relief System |
The WULI WN-1004A-5M is a turnkey high-pressure misting unit engineered for international manufacturing facilities, commercial agricultural complexes, and industrial infrastructure projects. Designed to run natively on 50Hz / 230V regional power grids, it eliminates the need for external voltage converters while driving up to 65 precision misting nozzles (0.15mm). Equipped with an adjustable 2–10s auto-drain pressure relief valve, the system automatically discharges trapped line pressure and flushes stagnant water upon shutdown—preventing end-of-cycle nozzle dripping and suppressing waterborne bacteria in pipeline loops.
Target Applications
- Industrial Manufacturing Plants: Rapid evaporative cooling and localized dust suppression in large indoor spaces.
- Commercial Greenhouses: Automated climate management, fine humidification, and temperature control.
- Continuous & High-Duty Operations: Automated timed drainage maintains line cleanliness during high-frequency cycling.
- Bulk Material Handling: Active dust control at transfer hoppers, conveyors, and storage bays.
- Environmental & Waste Treatment: Wide-area odor control and localized neutralizer spraying.
Heavy-Duty Engineering Features
- 50Hz Impedance-Matched Motor: Specifically designed for European, Middle Eastern, and Southeast Asian power standards. Ensures cool, energy-efficient operation during continuous duty cycles under 50Hz power grids.
- 2–10s Adjustable Auto-Drain Relief (Anti-Bacteria & Anti-Drip): Triggers an automated 2-to-10 second flush and pressure dump when cycling off. This eliminates residual pressure to stop nozzle dripping instantly while reducing stagnant water where bacteria can breed. (*Note: Due to fixed timed duration, water in extended line runs will not be 100% evacuated; longer drain settings slightly extend repressurization time on the next start.)
- Heavy-Duty Mechanical Timers (EMI-Immune): Built with robust mechanical cams and relays that remain completely immune to voltage fluctuations and electromagnetic noise common in raw industrial environments.
- Recommended Timer Duty Cycles: To optimize motor cooling and prolong equipment service life, set Run Time ≥ 5 seconds and Pause Interval ≥ 15 seconds when configuring the dual-knob timer controls.
- Turnkey Skid-Mounted Design: The pump head, unloader valve, filtration assembly, and electrical controls are fully integrated on a rugged frame. Simply connect water supply and main power for immediate deployment.
Engineering Specifications & Procurement Benefits

Frequently Asked Questions (FAQ)
Q: How do I select between 50Hz (5M) and 60Hz model options?
A: Equipment selection must match local grid frequency. Use 60Hz models for Taiwan, North America, and 60Hz / 220V regions. Choose this WN-1004A-5M model for 50Hz / 230V markets across Europe, Southeast Asia, the Middle East, and Mainland China to ensure proper motor cooling and performance.
Q: How should I adjust the auto-drain pressure relief timer, and what is its operational effect?
A: The drainage duration can be adjusted between 2 and 10 seconds. Longer settings provide more thorough line depressurization and flushing, maximizing drip protection and bacteria prevention. However, longer settings slightly increase the time needed to re-pressurize the network on startup.
Q: Does the auto-drain relief feature completely evacuate all water from the piping line?
A: No. The auto-drain feature executes a short timed pulse (2–10 seconds) at shutdown to dump pressure and flush immediate residual water. In long piping networks, complete water removal cannot be achieved in a short pulse. For extended seasonal shutdowns (e.g., winter storage), manual line draining is still required.
