Type list with performance data

3 About the product

The metering system DULCODOS® Ammonia is used for the gas-

tight transfer and dilution of ammonia water to common metering

concentrations and for automatic metering into the feed water.

Ammonia (NH3), or diluted in water: Ammonium hydroxide

(NH4OH) is used for the alkalising and binding of free carbonic acid

in boiler water and condensate.

Common stock solutions: from 5% to 25% NH3 (% w/w) (ammonia

water).

The usual metering concentration is 0.1% ... 2.5% NH3 (% w/w).

4 Safety chapter

The following signal words are used in these operating instructions

to denote different levels of danger:

Signal word Meaning

WARNING Denotes a possibly hazardous

situation. If this is disregarded,

you are in a life-threatening sit‐

uation and this can result in

serious injuries.

CAUTION Denotes a possibly hazardous

situation. If this is disregarded,

it could result in slight or minor

injuries or material damage.

The following warning symbols are used in these operating instruc‐

tions to denote different types of danger:

Warning symbol Type of danger

Warning of a dangerous area.

Warning of hazardous electrical

voltage.

Warning of a risk of explosion

nThe metering system DULCODOS® Ammonia is only intended

for batching ammonia water in common concentrations of up to

max. 25% into standard solutions of 0.1% to max. 2.5% and

metering this into water-steam circuits or into steam and con‐

densate systems.

nThe metering system DULCODOS® Ammonia may only be

used after correct installation and start up - according to the

technical data and specifications outlined in these operating

instructions and the operating instructions for the individual

components.

nThe metering system DULCODOS® Ammonia is not intended

for other uses.

nIn the event of a modification, the operator or the contractor he

has appointed becomes the manufacturer of the modified

system in accordance with EC Regulation 2006/42/EC – with

the corresponding obligations.

Safety chapter

nThe metering system DULCODOS® Ammonia is not intended

for metering other chemicals, such as sodium hydroxide solu‐

tion.

nThe metering system DULCODOS® Ammonia is not intended

for the metering of gaseous or solid media or other liquid

media.

nYou are obliged to observe the information contained in the

operating instructions at the different phases of the unit’s

service life (such as assembly, installation etc.).

nThese operating instructions contain a summary of the impor‐

tant functions of each of the components used.

The technical information and operating instructions for the

components used form an integral part of the entire operating

instructions and must be observed.

nMake sure that the metering systems are only operated by

trained and authorised personnel, see table.

Safety chapter

WARNING!

Danger from hazardous substances!

Possible consequence: Fatal or very serious inju‐

ries.

Please ensure when handling hazardous sub‐

stances that you have read the latest safety data

sheets provided by the manufacture of the haz‐

ardous substance. The actions required are

described in the safety data sheet. Check the

safety data sheet regularly and replace, if neces‐

sary, as the hazard potential of a substance can be

re-evaluated at any time based on new findings.

The system operator is responsible for ensuring

that these safety data sheets are available and that

they are kept up to date, as well as for producing

an associated hazard assessment for the worksta‐

tions affected.

WARNING!

Danger of electric shock

Mains voltage may be present inside the pump

housing and the switch cabinet.

– Immediately disconnect the system from the

mains power supply if the pump housing or

switch cabinet has been damaged. Only return

the pump to service after it has been repaired

by authorised personnel.

CAUTION!

Please also observe the operating instructions for

the metering pump and any other units which may

be fitted.

CAUTION!

Do not climb onto the system or parts thereof - the

metering station cannot support the load, could

leak or topple over.

NOTICE!

Warning of illegal operation

Observe the regulations that apply where the

device is installed.

The following dangers could arise if incorrectly operated or mis‐

used:

Water pollution and damage to health

nWater pollution and damage to health due to escaping liquids.

nDamage to health from the inhalation of ammonia vapours.

nDangerous reactions due to contact with other chemicals.

Safety information

Potential danger from the system

Safety chapter

Take special precautions with storage and metering. The specific

potential danger and resulting hazards should be taken from the

current material safety data sheet for the substance used.

Danger of explosion

nRisk of explosion due to trapped ammonia-air mixtures.

A potentially explosive ammonia-air mixture (lower explosion limit

15.4 vol.%, upper explosion limit 33.6 vol.%) can form in the inte‐

rior of the metering vessel and also in the interior of the supply

drum 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 therefore

designed to be intrinsically safe “i” with an explosion-proof design.

Pay attention to any static charge when connecting or replacing a

supply 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 supplied

by the chemical supplier in the event of any accidents with

ammonia water.

If ammonia water escapes, evacuate the room, put on protective

equipment, seal the leak and, if necessary, collect the escaped sol‐

ution and dispose of!

Refer to the material safety data sheet for ammonia water provided

by the chemical supplier.

Refer to the material safety data sheet for ammonia water provided

by the chemical supplier.

The “GESTIS Substance Database” published by the IFA Institute

for Occupational Health and Safety of the German Social Accident

Insurance provides valuable information.

Direct contact with ammonia water may occur when changing over

the supply drum and during maintenance work. Observe the

instructions.

Emissions of ammonia gas are not expected due to the gas-tight

design of the storage tanks and the downstream exhaust air

adsorber. This is the case providing the adsorber is regularly

changed.
