HOUNÖ Open Drain Box 

Centralised drain management – one robust system for 1-2 drains.

The HOUNÖ Open Drain Box is designed for professional kitchen and process environments where one or two drains from ovens need to be collected and managed efficiently. Instead of letting each drain run separately or connecting through improvised solutions, this open drain box serves as a compact and reliable collection point before water and liquids flow to the main drain or pump.
