Yes, most commercial freezer rooms require a drainage point. This is because freezer rooms often have condensation from the refrigeration system, which can accumulate on the floor. A drainage point is necessary to properly remove this condensate and prevent water damage to the floor and other parts of the room.In some cases, a commercial freezer room may have a built-in drainage system, but in other cases, you may need to install a separate drain. The specific requirements for your commercial freezer room will depend on the size and type of unit you choose, as well as local building codes and regulations.It's always best to consult with a professional when setting up a commercial freezer room to ensure that all necessary drainage and other requirements are met.
