ueberwachungseinrichtung for 2009 u.dgl. bathrooms, in particular galvanic bath room

摘要

In a supervisory system for noxious (galvanic) baths the pressure produced by a pump in the cooling or heating coils is kept higher, in operation, than the static bath pressure. To prevent any toxic substance, which may have leaked into the coils at a standstill, from poisoning the drains, a 3-way valve in the outflow line is opened by a time switch long enough to a detoxification system to ensure the complete removal of the contents of the coils. The 3-way valve is then returned to the drain position.
