A New Solution Born from On-Site Needs—Introducing the RJ3-GEMD
The new rotating nozzle RJ3-GEMD was developed following an inquiry from overseas.

The end user, a leading ethanol producer in South Asia, needed a reliable way to clean multiple large tanks (each approximately 20 m in diameter) used in the fermentation step of starch-based bioethanol production. The other rotary nozzles they had been using often suffered from motor corrosion, impact damage, and component detachment/failure, making stable operation difficult.

To address these issues, we developed the RJ3-GEMD, a motor-driven, high-flow, highly durable rotating nozzle.
It delivers wide spray coverage (approx. 15–30 m in diameter) ideal for large tank cleaning, while offering long-term reliability even under continuous operation. The motor-drive design also provides flexibility in pressure and flow rate settings, allowing optimized cleaning performance for each facility.

In an ongoing field trial that has run for over a month, the RJ3-GEMD has operated flawlessly in regular cleaning cycles, earning strong praise from the client.

Powerful, reliable, and cost-efficient for regular maintenance of large-scale process tanks.

A New Addition to the RJ Series Lineup

New Models in the RJ Series: RJ3-4H / RJ3-2H Despite their palm-sized bodies, the new RJ3-4H and RJ3-2H deliver powerful cleaning performance. Many customers have automated tank cleaning with the RJ Series, significantly reducing manual workload and cleaning time. (Operating pressure ranges vary by model) > More details

RJ3-MD-L Series (Motor-Drive, High-Flow Type) Compared with the existing RJ3-MD series (4.2–104 L/min at 0.3–15 MPa), the RJ3-MD-L achieves approximately 1.5 times higher flow rate (8.2–126 L/min at 0.1–2.0 MPa). Ideal for applications requiring larger water volumes for efficient cleaning.​​​​​​ > More details
