ELCO FNC 879 SCALE CLEANER is composed of composite acid, corrosion inhibiter, surface active assistant, solvent . It is a colourless transparent liquid . Affinity is strong, can be mixed with water for any ratio . ELCO FNC 879 Scale Deposit Cleaner can fast and efficiently remove water scale deposit , water mark and other metal salts etc. impurity which is not solved in water, the scale deposit removing effect is good, applying is safe and reliable .

ELCO FNC 879 suits to be used for cleaning scale deposit and its dirt of heat exchanger, air cooler, air compressor water pump, water tower, liner, water tube etc. various device, efficiently increases the heat exchange efficiency of equipment .  
Before applying ELCO FNC 879, must drain away all water in the system, commonly may be diluted by 5~20 times water and mixed evenly for use

ELCO FNC 880 SCALE DPRESSOR AND MAINTAIN AGENT FOR WATER COOLING TOWER is composed of sodium salts, organic metal compound, surface active agent, corrosion inhibiter and depressor, pH value modifier etc..It is a water soluble matter, a light yellowish transparent liquid, it can prevent efficiently metal surface corrosion, obstructs water scale deposit and other deposit forming, It is non corrosion to stainless steel, copper, cast iron etc.

ELCO FNC 880 suits to be used for corrosion inhibition and scale depression protecting action of enclosed type circulating system of the low speed, medium speed, high speed diesel engine, also for other industrial water circulating cooling system,. and thus increases the heat exchange efficiency of equipment .
When the cooling system has applied ELCO FNC 879 scale deposit cleaner to clean system,   
applies with a ratio of 4 kg of ELCO FNC 880 mixed by 1000 kg water , thus attains optimal effect for protecting cooling system .
