Industrial STS-5 kg/h Ultrasonic Humidifier, Stainless UH heads, Dual Outlet, Variable Circulating  fan control.

High-Volume, Dual Outlet Humidity for Commercial Grows.

The STS 5kg/h Ultrasonic Humidifier is the essential workhorse for growers requiring professional-grade atmospheric control with straightforward integration. Vetted and tested under our strict Sustainability Testing Station (STS) standards, this unit provides maximum value and consistent performance without the premium cost of full smart automation.

Built for continuous industrial operation using the same proven ultrasonic atomizer technology found in our flagship STS Smart Series.

Professional Performance & Core Technology

This unit is built for continuous commercial use and delivers reliable output using the same advanced ultrasonic technology found in our high-end line:

• High Output: Delivers a reliable 5 kg/h of cool, sterile micro-mist.

• Upgraded Stainless Steel Internals: Powered by a dedicated Gen² Ultrasonic Transducer Head (CL-MK10-5). Unlike consumer units that rely on fragile ceramic discs that pit and crack, our configuration utilizes rugged stainless steel discs built for raw longevity and continuous farm abuse.

• Droplet-Free Fog: Creates ultra-fine vapor particles that flash-evaporate into the ambient air, eliminating the risk of wetting surfaces, growing media, or damaging sensitive electronics.

Simplified Integration and Control

The STS-5kg/h is engineered for practical, hands-on control and easy integration into your cultivation space’s climate control system:

• Dual Manifold Outlets (Top G1 / Front G2): Optimized for direct connection to standard 75mm PVC-U ventilation pipe networks, allowing for effective centralized distribution of humidity right where your racks need it.

• Variable Fan Control: Adjust the integrated circulation fan speed manually via an analog dial to fine-tune atmospheric movement and mist throw through your connected manifold/ducting.

• Durable ABS Body: Built with a robust, lightweight ABS plastic chassis that offers excellent corrosion resistance in high-humidity environments while maintaining a highly cost-effective footprint.

Ideal Applications:

• Mushroom Fruiting Rooms & Cleanroom Lab Incubation

• Hydroponic/Aeroponic Greenhouses & Propagation Tents

• Seedling and Grafting Areas

• Printing shops, spray booths, or industrial workshops requiring strict static humidity control

Important Listing Notes:

• Piping Compatibility: The PVC pipe and elbow shown in product imagery are for reference only and are not included. The molded machine ports accept a direct slide-fit with standard 75mm PVC-U vent pipe, or can be easily adapted to normal 80mm uPVC round gutter downpipes using a standard hardware flexible coupling.

• Heavyweight Performance: This is a true 5kg/h high-volume machine, not the restricted 3 kg/h model standard to this bracket size.

• Manual Control: This is not a digital SMART system with integrated RH controllers; it is built for direct power-toggle automation or simple manual operation. Can be paired with a high humidity controller for SMART operation.

Every STS machine is evaluated under our Sustainability Testing Station (STS) program for durability, reliability and practical performance before being offered for sale. Do not hesitate to contact us for more information or to analyze your humidity requirements.
