Very effective cleaner that is clear, yellowish green with anti fungal properties. Its a dispersing cleaner for the control of fouling smell by marine growth such as algae, shellfish, mussels, barnacles, micro-organisms and fungal growth in the sea water. Also effective in cleaning sides of cooling. 

Another very important reason for using RXSOL-40-4008-027 Biocides in cooling towers is to prevent the growth of Legionella, including species that cause legionellosis or Legionnaires' disease, most notably L. pneumophila, or Mycobacterium avium. The various Legionella species are the cause of Legionnaires' disease in humans and transmission is via exposure to aerosols—the inhalation of mist droplets containing the bacteria. Common sources of Legionella include cooling towers used in open recirculating evaporative cooling water systems, domestic hot water systems, fountains, and similar disseminators that tap into a public water supply.

RXSOL-40-4008-027  biocides function in eradication of sulfate reducing bacteria, aerobic and anaerobic bacteria that are formed and found in Cooling Tower Water.Micro Biocides are very vital for Closed and Open Circuit Cooling Water Treatment.

TCF (Totally Chlorine Free) micro biocides are compatible with heat transfer fluids (HTF) and can be used without any fear of corrosion of chlorine addition to the system or depletion or degradation of HTF and corrosion of PHE (plate type heat exchangers)

The disadvantages of not treating the closed circuit water can be equally troubling for the system operator:-
1. Leakage in PHE and AHU due to corrosion
2. Plugging and clogging of tubes and reduced flow rate
3. REduced heat transfer
4. Need of regular descalling that incurs shutdowns, loss of labor and time
5. Fouling of brine of chiller water

Chemical tratment removes dissolved oxygen that cause oxidation of metal to metal oxide i.e., Iron + Oxygen = Iron Oxide (Rust)

The chemical also contains a specific inhibitor to protect copper from corrosion and removes/prevents any sort of scale formation in the system.

Keep locked up.. Keep container dry. Keep away from heat. Keep away from sources of ignition. Keep away from combustible material.. Do not ingest. Do not breathe gas/fumes/ vapor/spray. Never add water to this product. In case of insufficient ventilation, wear suitable respiratory equipment. If ingested, seek medical advice immediately and show the container or the label. Avoid contact with skin and eyes. Keep away from incompatibles such as oxidizing agents, reducing agents, combustible materials, organic materials, metals, acids, alkalis

Before testing of Nitrite level, Here is some point and guideline,  what you need to do. : 1 take the following readings; pH, TDS (uS), and nitrite level.and record. 2 add the Chemical your are using. 3. wait for a period of time for the sysem to circulate. hours> 4. Re check the readings. and record. 5 track these readings
for a period of time.

If the TDS and Nitrite drop you have a leak/ unknown makeup. if the TDS stays stable and the nitrite drops you have a biological problem. Bacteria that convert nitrite to nitrate.

Solution ::: Use DI water in place of general water, And also use. Algaecide to control Bacterial growth inside water system ... http://rxmarine.com/Biocide-Algaecide
