DM - 140 is a new product that is formulated by Delaran Rooz co. for neutralizing descaler and acid in boilers ,heat exchangers,cooling jacket system in generator and engine and especially for neutralizing descaler
which is remained in the billge after descaling machinerie s section .
DM - 140 is a pink - red solution and when reacts with a acid solution it s color disappeares and foam forms.
this two properties shows the existance acid in the system and adding more DM- 140 is necessary.
adding DM - 140 will be stopped when no foam is formed and the color of the solution remains pink - red , it means the acid or descaler is neutralized compeletely and you have enough tim to drain the solution
it is sujested to use DM -140 after using descaler to prevent local corrosion .
Direction for use
a: for boiler heat exchanger and cooling jacket system:
1) drain descaler
2) circulate 1-3% DM - 140 for 2-4 hours if the pink- red of solution disappeared add 20 liter DM- 140 and continue circulating until the pink –red is unchanged for one hour. itmeans neutralizing is finished.
3) drain DM - 140 solution
4) wash system with fresh water.
5) the system is ready for use
b: neutralizing remain descaler in the billge.
1) add gradually DM - 140 to the remained descaler in the billge , pink-red is des appeared and forns wait a moment foam is effaced .
3) add some more DM - 140 until no foam is formed and pink - red dose not dis appear
4) stop adding DM - 140 now there is a neutraized solution with pink-red color and a PH between 7-10
5) you have enugh time to drain the solution.
6) after the newtralizing of descaled system by neutralizer DM-140 the fixing PH of the circulating neutralizer about 9 – 10 shows the ending of newtralizing procedure .
