■ Before Installation: Lingering “Putrid Odors" and the Grueling Task of Scooping Grease

At a company cafeteria located within a Tokyo office building, hundreds of lunches are served daily, causing massive amounts of oil and food residue to flow into the kitchen’s grease trap. Consequently, especially during the summer and after weekends, a distinct, putrid odor would fill the kitchen, raising severe concerns about the smell leaking into the adjacent dining and office areas. Furthermore, to meet the building’s strict hygiene standards, staff had to manually scoop out the grease every day—a grueling task that caused significant physical and mental exhaustion.

⚠️ Serious Concerns Plaguing the Site

・ Risk of Odor Diffusion: Concerns over odor complaints within the corporate office building.

・ Grueling Cleaning Tasks: Staff exhaustion from manually processing massive daily grease accumulation.

・ Limitations of Manual Hygiene: Anxiety over pest infestations that manual cleaning alone cannot fully prevent.

■ The Decisive Factor: “Compact Retrofitting" and “Absolute Safety"

In the limited kitchen space of a downtown office building, large-scale renovation was impossible. The AIC Grease Ozonizer is remarkably compact and can be seamlessly retrofitted directly into existing grease traps, which was highly evaluated. Additionally, because it uses only the power of ozone to powerfully decompose fats without relying on chemicals, it offers the “ultimate safety" required for a kitchen preparing meals for employees, making it the decisive choice.

■ Post-Installation Results: “Elimination of Odors" and a “Massive Reduction in Cleaning Time"

After installation, the most immediate effect was on the “smell." The unpleasant putrid odor drifting through the kitchen vanished within a few days, leaving the air fresh and clean.

Furthermore, the thick, sludgy lumps of grease were broken down by the ozone into a smooth liquid, drastically reducing the daily manual scooping work. The time spent on cleaning has been significantly shortened, and the on-site staff happily report that “cleaning has become unbelievably easy."

✅ Resolution of Odor Troubles: The fear of smells leaking into the building has been completely reduced to zero.

✅ Freedom from Heavy Cleaning Labor: Grease scooping tasks dropped dramatically, easing the staff’s physical burden.

✅ Maintaining a Hygienic Kitchen Environment: Eradicating pest breeding grounds and keeping the area spotless.

Frequently Asked Questions from Facilities Considering Installation

Yes, absolutely. The AIC Grease Ozonizer features a highly compact design. It can be flexibly retrofitted in tight kitchen spaces without getting in the way, such as being mounted directly on the wall.

While it depends on the site conditions, in most cases, you will clearly realize a significant reduction in the distinct putrid and oxidized oil odors of the grease trap within a few days to a week of operation.

Cleaning does not become “zero," but the workload is drastically reduced. While you still need to empty the strainer basket of large vegetable scraps, the most unpleasant and grueling task of “scooping out solidified grease" is massively reduced, making daily management incredibly easier.

No, large-scale plumbing work or digging up the kitchen floor is completely unnecessary. Installation is completed with a simple process of routing a thin tube into the existing grease trap and securing a standard power supply (100V).
