Cooling Water Treatment ROCOR NB Liquid chemicals Supplier Manufacturer visakhapatnam India

ROCOR NB Liquid is the ideal corrosion inhibitor for closed heating or cooling systems, such as diesel engines, compressors, process cooling systems, etc. Rocor NB liquid is one of popular cooling treatment chemical.This product contains nitrite and borate as major component along with new generation corrosion which makes new advance Rocor NB then others.Many experiment oroves that water of closed cooling system required special treatment to prevent pitting corrosion and scale formation. special Blend of nitrite and borate with watersoftening polymer plays excellent role in cooling system.Rocor NB Liquid is a non-chromate, non-phosphate, free flowing liquid that is extremely effective for controlling corrosion while avoiding the pollution and toxicity problems associated with chromate based inhibitors.

ADVANTAGES

* Controls attack on piping, valves, pumps and heat exchangers by producing a protective film on all exposed metal surfaces - iron, steel, copper, copper alloys, aluminium and brass.

* Inherent Buffering agent automatically adjusts pH at the preferred level.

* Does not adversely affect pump glands, rubber hose, water seals, and valve packings.

* Prevents deposition of copper on ferrous surfaces by "tying up" any copper which might be introduced. This eliminates the possibility of attack caused when copper deposits on steel to form galvanic cells or corrosion couples.

* Compatible with alcohol and glycol base antifreezes.

* Does not contain chromate or produce colour in the treated water, thereby eliminating the possibility of stain.

* Liquid form simplifies usage and eliminates waste.

APPLICATION

Feed the Rocor NB Liquid into any convenient point in the system with a chemical proportioning pump or slug feed by using an appropriate by-pass feeder. Rochem can supply suitable dosing equipment.

DOSAGE

Concentration level in the system must not be allowed to drop below 1500 ppm as nitrite (N02). For economical reasons try to maintain nitrite evel between 1500 ppm to 2000 ppm although higher nitrite levels will not cause operating difficulties. Nitrite level is obtained by using a simple colourimetric test for nitrite.
