Application example

* Before
Parts cleaning machines degrease and flush dusts.
It is required to clean tanks and to change alkali cleaning fluid every 2 months (200L) due to the contamination with oil and dusts.
The cost to treat the waste fluid is 40,000 yen (US$400).
When it is close to the fluid-change due date, they have a number of uncleaned parts (defectives).

Benefits with RRR system
It is required to clean tanks and to change cleaning fluid only once per 6 months.
You are able to filter and recycle the used process oil by mixing with new oil.
The new oil you need to refill for the consumed oil at the machine process is one-third of the pre-application of RRR systems.

Filter change:
OS-Oil Separator (22289 x 1, 26500 x 3): once per 2 months
WS-WD-AD (25470 x 1, 20101 x 1): once a year
SE-100N-YT (20000 x 1): once per 2 months
Recycling: 30L of oil every week

Water-base Cleaning machines with only one type of contaminating oil.
