Introducing a case that solved the layout and slope issues of the drainage pipe during the installation of a new refrigerated showcase!

We would like to introduce a case where the "General Drainage NSB (ZA-100NSB+)" was adopted in conjunction with the expansion of the sales floor area during the supermarket store renewal. In this facility, there was a challenge of wanting to place refrigerated display cases in areas where they had not been installed before, but due to the absence of drainage pipes, it was necessary to pump the drainage. Thanks to our proposal, a cost-effective model specifically designed for drainage from refrigerated display cases, equipped with a backup function, was adopted. The piping route utilized the ceiling space, with a discharge pipe raised 3 meters and routed horizontally through the ceiling to the pipe shaft. [Case Overview (Partial)] ■ Installation Location: Supermarket ■ Model: General Drainage NSB (ZA-100NSB+) ■ Connected Equipment: Refrigerated Display Case Drainage *For more details, please download the PDF or feel free to contact us.

【Summary of Other Cases (Partial)】 ■Challenges <Requests> - With the store renovation for expanding the sales floor area, we want to place a refrigerated showcase in a location where it has not been installed before, but we need to pump the drainage because there are no drainage pipes. - Since it is a tenant inside a train station, a backup system with two pumps is essential to avoid water leaks due to pump troubles. - It would be even better if it can be compactly installed and is inexpensive. ■Proposal Details <Design and Construction Points> - The piping route will utilize the ceiling, with the discharge pipe rising 3 meters and running horizontally within the ceiling to the pipe shaft. - The installation location will be under the fixtures next to the refrigerated showcase. *For more details, please download the PDF or feel free to contact us.
