Restaurants, Cold Rooms, Food Service — Sanitize and Deodorize with Master Ozone Generator
One machine — kills pathogens + removes odor + no chemical residue on ingredients.
Chef Athit's story — fine dining in Thonglor
Chef Athit, 39, owner and head chef of an 80-seat Thonglor fine dining restaurant. Premium ingredients — Japanese fish, Australian beef, organic produce from select farms — daily cold-room value in the hundreds of thousands of baht.
The hardest stress: cold-room cross-smell — fresh fish next to butter and cheese. Some days ingredients look fresh but smell off. After a HACCP auditor from a major catering client flagged it, Athit invested in Ozone Treatment.
Master Ozone Generator runs in the cold room during off-hours (10 PM–6 AM) every two weeks — air smells reset and pathogens reduced. Ingredients keep longer, Food Cost dropped 3–5%.
Cold room and kitchen challenges
- Mixed ingredient odors — fish, beef, butter, cheese, produce in one cold room
- Listeria, Salmonella, E. coli — cling to surfaces hard to clean
- Mold in paper and wood — fixtures that survive cold but retain moisture
- Oil smell in kitchen — embedded in walls, ceilings, hoods
- HACCP cleaning downtime — partial kitchen closures
- Sanitizing chemicals corrode stainless — frequent use causes rust
Food business risks
- Ingredient spoilage — higher Food Cost
- Customers detect off-smell in food — negative reviews
- HACCP/GMP audit fail — lose certification
- Foodborne illness — legal exposure
- Stale restaurant ambiance
