Sound pressure level LpA < 70 dB according to EN 3746

The system is provided with the following protection equipment,which prevents large quantities of ammonia from escaping, or theresulting ignition of an ammonia water-air mixture:n The level switch in the metering vessel prevents overflowing.n The system is designed so that the transfer from the storage

tank to the metering vessel is via a vapour recovery line.n The aeration and venting of the system is through an active

carbon filter, which absorbs the escaping ammonia gas.n The lid of the dosing tank protects the user from ammonia gas.

It needs to be secured by a seal when operating with ammonia.n The level switches in the metering vessel and in the dosing

tank are designed to be explosion-proof and intrinsically safe “i”with an appropriate explosion-proof intrinsically safe “i” switchamplifier.

Further recommendations, the implementation of which is howeveroutside our area of responsibility:n Place the dosing tank in a collecting pan.

7 Functional descriptionThe DULCODOS® Ammonia system is used for the gas-tighttransfer and dilution to usual metering concentrations and thenautomatic metering into the feed water.The dosing tank (12) needs to be filled with de-ionised water tobatch a diluted usable ammonia water solution. The transfer pump(4) semi-automatically fills concentrated ammonia water solution(max. 25%) from the supply drum (1) into a metering vessel (9). Anappropriate amount of this concentrated solution from this meteringvessel needs to be left in the dosing tank to obtain a final concen‐tration of between 0.1% ... 2.5%.The manual stirrer (10) mixes the solution until it is homogeneous.A chemical vapour lock (adsorber) (7) is fitted on the meteringvessel to prevent ammonia vapours from escaping into the envi‐ronment.The metering pump (5) meters the ready-to-use ammonia solutionfrom the dosing tank at the corresponding point of injection (6).Metering can be provided on-demand using external control of themetering pump.Optional fault indicating relays on the pumps can report faults on acontrol panel.
