RADICLEAN PASSIV
RADICLEAN PASSIV
Neutralizing and Passivation Chemical for Closed Loop Water, Glycol and Brine system
RADICLEAN PASSIV is a unique cleaning cum neutralizing and passivating agent for closed loop systems. It
plays a vital role in keeping the closed loop system operating efficiently. It effectively removes foulants such as dirt, solder deposits, corrosion products, water derived mineral deposits, carbon, grease, oil films or foulants etc. Cleaning of new system with RADICLEAN PASSIV is just as important as cleaning old ones, since the metal surface of new systems may be coated with oil or film, which can cause reduce heat transfer efficiency due to low thermal conductivity.
Passivation with RADICLEAN PASSIV creates a Passive coating on the system metal that ensure optimum
system performance, by reducing the chances of metal oxidation or corrosion (rusting) and retains the heat
transfer efficiency close to design. Water or Brine dosed after Passivation retain their properties and do not
foul early.
WHAT IS PASSIVATION
Passivation is a process by which a stable protective film is formed which is fully-conductive and inhibits further dissolution of metal. Passivation also eliminates chances of flash rusting after acidic cleaning of metal. Chemically cleaned or water jetted boiler and heat exchangers should always be passivated to avoid excessive fouling by iron oxides in service.
BENEFITS
✓ Effective cleaning and removal of foulants with ease
✓ Promotes Power Saving by improving heat transfer in the chiller
✓ Modifies metal/surface for corrosion protection
✓ Removes foreign metal contaminants to prevent bi-metallic corrosion cell
✓ Inhibits Flash resting after de-scaling
✓ Biodegradable and easy to dispose
PRODUCT SPECIFICATION
Appearance : White granular powder
pH : 12.0-13.0
Solubility : Completely soluble in water
Biodegradability : 100%
DOSAGE
RADICLEAN PASSIV should be dosed directly to the system tank containing water. After dilution the solution should be re-circulated for 6 hours to enable cleaning and forming a passive coating on the metal surface. Once the system is cleaned, the solution can be drained off or stored for future cleaning jobs, if not severely fouled or dis-colored. For re-using the same solution for more jobs, ensure that the solution pH is above 11.5. If not, then add more RADICLEAN PASSIV.
Ideally for cleaning and Passivation of new systems up to 2% w/v RADICLEAN PASSIV is required. For old and severely fouled systems, de-scaling is recommended before Passivation. The quantity required of
RADICLEAN PASSIV for neutralizing and Passivation up to 2% w/v for re-circulation for 3-6 hours.
HANDLING PRECAUTIONS
Use proper human safety products such as Splash goggles, lab coat, vapor respirator, gloves and boots while
handling and applying chemicals. Avoid contact with skin, eyes and clothing, wash with water thoroughly after handling. In case of eye contact, flush it with fresh water and obtain medical attention. Should not be injected.
STORAGE
RADICLEAN PASSIV should be stored in original containers in cool and dry place, away from sources of heat,
flame and direct sunlight.
