NAS-S3:- IS DESIGNED TO REMOVE THE SCALING & CORROSION PRODUCTS FOR ALL TYPE OF BOILER .IT IS LIQUID FORMULATION TO REMOVE HARDNESS & LOW CONCENTRATED SILICA SCALES THAT CAN BE REMOVED OFF LINE BY CIRCULATING , IT’S DILUTE SOLUTION OF THE CHEMICAL. IT IS A BALANCE FORMULATION OF HYDROCHLORIC ACID, DISPERSANT, WETTING AGENTS & CORROSION INHIBITOR
FEATURES
1. POWERFUL DESCALENT
NAS-S3 IS SAFE & NON CORROSIVE FOR DESCALING, IT DISSOLVES HARDNESS SCALES QUICKLY & COMPLETELY.
2. SAFE FOR METALS
NAS-S3 CONTAINS A SYNTHETIC POLYMERIC CORROSION INHIBITOR WHICH FORMS PROTECTIVE FILM ON THE PARENT METAL SURFACE TO PREVENT ACID ATTACK
3. DETERGENT ACTION
NAS-S3 CONTAINS A WETTING AGENT WHICH EMULSIFIES OIL GREASE PRESENT IN THE DEPOSITS. THE DETERGENT ACTION OF NAS-S3 LOOSES DIRT, SILT, ETC… WHICH CAN BE REMOVED DURING WATER FLUSHING

NAS-S2:- WITH THE HELP OF NAS-S2, IF NECESSARY TO CLEAN THE INSIDE OF THE NEW BOILER OF OIL GREASE USED AS TUBE ROLLING LUBRICANTS, THREADING AND / OR OTHER VARIOUS REASONS BEYOND THE MANUFACTURER’S CONTROL. SINCE THESE COATINGS MAY LOWER THE HEAT TRANSFER RATE OF THE HEATING SURFACES, FAILURE TO REMOVE THESE COATINGS WILL RESULT IN YOUR UNIT FOAMING, PRIMING, CARRY-OVER OR OTHER DAMAGE
A) COOLING TOWER WATER TREATMENT CHEMICALS
1. COMBINATION OF POLYMER & AN ORGANO-INORGANIC FORMULATION OF LIQUID CHEMICALS i.e. NAS-C1 TO NAS-C10
2. NAS-C1 /NAS-C2 is based on cathodic-anodic corrosion inhibitor NAS-C2 based on Co-Polymer, Zinc Organophosphonat based chemistry for MS /SS and copper Corrosion protection. It is phosphate base chemical
3. NAS-C3 IT IS USED TO CONTROLE THE ALKALINITY IN COOLING TOWER IS CALLED AS ALKALINITY CONTROLLER

NAS-F1 Fuel, an integral part of the energy program, demands complete management. Though the refineries strive to maintain the quality of petroleum products, the efforts are concentrated on the high value top & middle distillates rendering little or no attention to the residual oils like furnace oil, heavy stock, etc. This generates a need for the treatment of fuel before firing.
NERO ACQUA SYSTEM has developed fuel additives. Engineers study the combustion equipment in totality, identify areas of concern; treatment programs to counter the problem areas and monitor effectiveness of the same to ensure optimum plant performance, in the most cost effective way. The Fuel oil treatment chemical range NAS-F1 which is a synergistic blend of antioxidants, sludge dispersants, wax inhibitors, corrosion inhibitors, slag modifiers, surfactants, detergents and combustion catalysts helps in improving the quality of fuel to be fired. The additives are designed to condition the fuel for better performance and operation of the system. It thus helps in prevention and precipitation of sludge formation, wax inhibition, prevention of filters/strainers/burner nozzle clogging, facilitates better fuel atomization & combustion, reduces slagging high and low temperature corrosion and controls emissions.
DOSAGE & APPLICATION: NAS–F1
It is recommended to dose NAS-F1 at the rate of 4.0-5.0 lit for every 10000 litres of F.O. /L D O

NAS-F6/NAS-F8:- IT IS USED TO REMOVE CARBON DEPOSITS FROM HOT OIL-GENERATOR (THERMIC FLUID HEATER), WHICH IS AVALABLE ONLINE DECARBONISING OR OFF LINE DECARBONISING
IMOPROVES EFFICIENCY OF THERMIC FLUID SYSTEM
REDUCES MANPOWER, BREAKDOEN OF THE SYSTEMS
