What is Fine Bubble Generator?
Fine Bubble generator HELIX NOZZLE generates Fine Bubble (Micro Bubble & Ultra Fine Bubble) that diameter is smaller than 100µm.
By applying water pressure to nozzle inlet, inside of the nozzle is evacuated and it draws in outside air by itself.
Suction air is sheared and mixed inside of the nozzle by its special internal structure, and it becomes fine bubble.

Characteristics of HELIX NOZZLE
01High Suction Capacity
Max flow ratio of suction air against applied water is 100%, which is one of HELIX NOZZLE’s advantages.
This enables powerful swirling flow including fine bubbles.
(Japan Patent No.6169749)
022 types of Bubbles
Fine bubble is divided into Micro Bubble (MB) and Ultra Fine Bubble (UFB), and they have different characteristics each.
MB seems to be white cloudiness and UFB is so tiny that it is invisible to the naked eye.
03Bubble Distribution
As for MB, 1 – 100µm, peak of the generation frequency is confirmed at bubble diameter of 16 – 20µm.

How HELIX NOZZLE works (VIDEO)
HELIX NOZZLE DEMO
Performed by TH-03 x 3pcs
Flow rate of suction air is gradually decreased by a regulator valve.

Application of HELIX NOZZLE
Case.1：Metal parts cleaning (Oil Removal)
Effect
Since fine bubble is much smaller than general bubble used in bubbling cleaning, gas-liquid surface is much larger and fine bubble can adsorb and remove contaminants efficiently.
HELIX NOZZLE can generate powerful swirling flow including fine bubble to an object resulting high cleaning performance.
-
Fine bubble can reach details of complicated surface.
-
Fine bubble can reach small space and separate stuck parts by machine oil.
Application Example
In metal parts cleaning after press processing, the customer used to remove attached oil by using ultrasonic cleaning machine with hydrocarbon detergent at first and then hand-washing, and obviously it took so long time.
After using HELIX NOZZLE, stuck of metal parts has been dramatically improved and shortened working time largely.
Case.2：Shower cleaning machine (Oil Removal)
Effect
Since HELIX NOZZLE is a nozzle type generator, installation into a cleaning machine is available easily at low cost.
-
-
Installation into existing machine
Following effects are expected by using HELIX NOZZLE
- Performance improvement
- Reduction of detergent amount
- Reduction of detergent temp.
- Reduction of cleaning time
-
-
Installation into existing machine
Case.3：Medical equipment cleaning
effect
Since fine bubble is much smaller than general bubble used in bubbling cleaning, fine bubble can adsorb and remove contaminants efficiently.
In addition, fine bubble can reach details of complicated surface.
HELIX NOZZLE can generate powerful swirling flow including fine bubble to an object resulting high cleaning performance.
For evaluation of medical equipment cleaning, sample blood attached on the equipment was cleaned and residue was estimated by ATP test. ATP was 32RLU after cleaning by HELIX NOZZLE and it passed the customer’s standard cleanliness of the conventional ultrasonic cleaning machine as well.
Application Example
HELIX NOZZLE has been used in pre-cleaning of heavily contaminated equipment or oil removal of new equipment especially.
Case.4：Improvement in grinding process
Effect
By generating fine bubble into cutting fluid, work environment, productivity, and fluid condition can be improved.
-
① Work environment
Fine bubble helps to keep cleanliness of pipe and tank by adsorbing and floating oil and sludges. It also inhibits growth of anaerobic bacteria that causes harmful odor.
-
② Productivity
Fine bubble in cutting fluid improves grinding ratio, quality of processed surface, and service life of grindstone since it can restrain clogging in grindstone during the process.
-
③ Fluid condition (Sludge separation)
Fine bubble increases collection efficiency of non-magnetic sludges into a centrifugal separator by floating separation in a tank.
Application Example
Fine bubble generation unit utilizing our technology is installed into a tank of grinding machine.
We have launched fine bubble generation unit “FINE GO”
from Sumitomo Heavy Industries Fintech, Ltd.
Fine bubble generation unit “FINE GO” utilizing our cultivated technology has been launched from Sumitomo Heavy Industries Fintech, Ltd. for grinding machines.
FINE GO can generate fine bubble in cutting fluid by only inserting suction and discharge hoses into an existing tank of a machine.
Case.5：Use in aquaculture
Effect
Fine bubble has been known to improve dissolved oxygen, bioactivation, and water quality, and utilized in various fields.
Since our HELIX NOZZLE is a nozzle type generator, it can be installed into various facilities simply and effectively.
