Take special precautions with storage and metering. The specificpotential danger and resulting hazards should be taken from thecurrent material safety data sheet for the substance used.Danger of explosionn Risk of explosion due to trapped ammonia-air mixtures.A potentially explosive ammonia-air mixture (lower explosion limit15.4 vol.%, upper explosion limit 33.6 vol.%) can form in the inte‐rior of the metering vessel and also in the interior of the supplydrum via the liquid phase depending on the temperature and con‐centration of the commercial ammonia water product.The built-in level switch in the metering vessel is thereforedesigned to be intrinsically safe “i” with an explosion-proof design.Pay attention to any static charge when connecting or replacing asupply drum!
Turn the Emergency Stop switch to “0” in the event of an emer‐gency or if liquid escapes from the system during pumping.Refer to the material safety data sheet for ammonia water suppliedby the chemical supplier in the event of any accidents withammonia water.If ammonia water escapes, evacuate the room, put on protectiveequipment, seal the leak and, if necessary, collect the escaped sol‐ution and dispose of!

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.

WARNING!Drops of hazardous ammonia water could bereleasedDrops of ammonia water can spill when changingthe supply drum.– Take appropriate protective measures as out‐
lined in the material safety data sheet whenworking on the system.
WARNING!Hazardous ammonia water can escapeAmmonia water can escape if the supply drum isnot handled correctly.
WARNING!Warning of explosive atmospheresAn explosive air-ammonia mixture can form withhigh concentrations of ammonia water – particu‐larly above 15% w/w – or also at high ambient tem‐peratures (at over 30 °C above 10% w/w).– Note the current regulations and technical reg‐
ulations dealing with ammonia and ensure ade‐quate ventilation.

Note for the operatorAn explosive atmosphere can form in the supplydrum with concentrations of over 15% w/w and/orhigh ambient and media temperatures. If a sparkjumps as the suction lance is approaching theopen opening of the supply drum, it could causethis atmosphere to explode.Therefore take appropriate measures, such as thefollowing:– Use an earthing cable to ensure that the suc‐
tion lance and storage tank have the samepotential just before inserting the suction lanceinto the storage tank.
– Use suction lances with a level switch withexplosion protection for Zone 0.
– Only connect the ammonia water to the systemin its original drum or in an electrically con‐ducting vessel.
As soon as the supply drum is empty, replace it with a fulloriginal supply drum.
