We deliver mist-free wet-film humidifiers for factories, warehouses, grow houses, and production lines—engineered for clean air and low maintenance. Microcomputer control holds 30–90% RH with automatic water supply/level protection and stainless-steel tanks, while models cover 6–65 kg/h capacity and 850–10,000 m³/h airflow for fast project sizing and reliable 24/7 operation.
Keep lines on-spec with stable humidity—without aerosolized mist. Wet-film media adds moisture while filtering the airstream; microcomputer control holds 30–90% RH and automates water supply/level protection for fewer manual checks.
Plant- or synthetic-fiber pads with high wettability and large specific surface area (typ. 350–500 m²/m³) to maximize contact efficiency. Media options available as non-toxic, flame-retardant, acid-resistant, and anti-mildew. Delivers strong, even humidification with no white mist; imported plant wet membranes also help purify the airstream.
Closed loop with pump, distributor manifold, and stainless-steel tank to ensure continuous wetting and uniform distribution across the pad. Built-in automatic water supply and water-level control with leak protection reduce manual checks; an auxiliary tank connection is available for extended runtime.
Project-sized fans drive process air through the wetted media to achieve rapid evaporation. Model airflow spans 850–10,000 m³/h with corresponding humidification of 6.1–64.8 kg/h, allowing you to match single rooms or ducted large spaces.
Integrated microcomputer control with humidity sensing for precise setpoints. Native wet-film set range 30–90% RH; when tied into Ruiwang environmental humidity controllers, facilities can run 10–95% RH control with ±1–±3% accuracy (application-dependent).

| How it works | Air passes through wetted media; moisture is added by natural evaporation. No visible mist. | High-frequency vibration turns water into fine droplets carried by airflow. Visible mist. |
| Humidity control | Typical set range 30–90% RH with programmable controller. | Wider set range 10–95% RH; models available with high precision control. |
| Capacity & airflow | 6.1–64.8 kg/h moisture; sized by process airflow 850–10,000 m³/h for rooms or duct systems. | Common options 3–35 kg/h (with higher models such as 42 kg/h); some integrated units rated 60–240 L/day for room/zone use. |
| Best fit | Large spaces, production lines, AHU/duct integration, areas requiring mist-free output. | Room- or zone-level humidification, flexible point deployment, quick installation. |
| Water & tank | Auto water supply and level control, leak protection, stainless-steel tank; optional auxiliary tank for longer runtime. | Auto water inlet and level control, stainless-steel tank; automatic fault display on supported models. |
| Hygiene & safety | Mist-free output; media options with mold-resistant properties; electronic protection functions. | Fine-mist output; protections such as timer, power-off memory, and defrost available on supported models. |
| Noise & disturbance | Fan-driven; perceived noise depends on airflow path and system design. | Very quiet atomization; fan noise is typically low at point of use. |
| Operations & maintenance | Periodic inspection/replacement of wet media; automated water management reduces routine checks. | Periodic cleaning of water path and atomizing components; self-diagnostics simplify troubleshooting. |
Brief answers to help engineering and procurement teams size, deploy, and maintain the system.
Our wet-film line covers 6.1–64.8 kg/h moisture output with handling air volume from 850–10,000 m³/h. Projects are typically sized by required process airflow and target RH.
Yes. The unit delivers strong, even humidification with no white mist and uses imported plant wet membranes that help purify the airstream.
A microcomputer controller provides automatic humidity regulation with a setpoint range of 30–90% RH.
The system integrates electronic detection with leak protection, automatic water supply, and automatic water-level control, using a stainless-steel tank; an auxiliary tank connection is available for extended runtime.
Periodic inspection and replacement of the wet-film media, plus standard checks of the water distribution path; the stainless-steel tank is mold-resistant and antibacterial to support hygienic operation. Service frequency depends on water quality and run hours.
Share your coverage area or process airflow (m³/h), target RH, installation (floor / duct / AHU), duct size & run length, water supply (tap / RO / DI; TDS if known), and voltage/phase—our engineers will size the right wet-film model and send a proposal within 24 hours.
