The drainage with plenty of fat from the pastry shop is safe with a model equipped with cleaning functions!

We would like to introduce a case where the "Dirty Waste Big NPC (BG-200NPC)" was adopted in a pastry shop located within a subway station. In this case, there was a challenge that made it impossible to install drainage pipes when setting up the shop in the subway station. Since the drainage contained a high amount of fats such as butter, a product that allows for self-maintenance (cleaning) was chosen. For maintenance purposes, a faucet and lighting fixtures were provided in the pump room, and due to the difficulty of installing ventilation pipes, a Canister L was installed. [Case Overview (Partial)] ■ Installation Location: Pastry shop within a subway station ■ Model: Discontinued Dirty Waste Big NPC (BG-200NPC) ■ Connection Equipment: Grease trap *For more details, please download the PDF or feel free to contact us.
