dvr Antifreeze Plus Corrosion Scale Inhibitor 25 Ltrs

Glycol antifreeze – corrosion & scale inhibitors

Antifreeze compound for cooling water systems , It is a  high quality effective blend of GLYCOL classified chemicals along with CORROSION inhibitor to protects all engineering precious metal including aluminium . Its chemically treated layer protect radiators and engines, against rust and corrosion. Its proper dose in cooling system gives full protection from corrosion.

It is biodegradable and does not have an environmental problem.

It also contains non-toxic multi-metal inhibitors to protect chillers and their associated cooling systems against corrosion and scale inorder to maximise heat transfer properties of the system. It should be diluted using ultrapure, demineralised, softened water.

An inhibited liquid coolant designed to protect against corrosion attack on base metals and also used to lower the freezing point of water



Solution Strength :
25 Ltrs RXSOL-16-4020-025 : 75 Ltrs Water gives freezing protection up to -140C  ‘or’ 25% solution (1 part anti-freeze to 3 parts water)
For extra cold / winter climate , increase to a 33% solution (1 part anti-freeze to 2 parts water) to give freezing protection down to -170C.



Using Procedure:

EYES : Irrigate copiously with clean, fresh water for at least 15  minutes. Seek medical advice.
SKIN :  Wash  immediately  with  plenty  of  water.  Remove  contaminated   clothing.  If  irritation  persists  seek  medical attention.  Wash  contaminated  clothing  before  using  them.
INHALATION : Remove to fresh air. If breathing is irregular seek medical advice.
INGESTION :  Obtain  immediate  medical  attention.  Induce  vomiting  only  if indicated  by  the  doctor.  Never  give anything  by  mouth  to  an  unconscious  person.



Antifreezes have been proposed with consist of water-soluble alcohols as the chief nonaqueous ingredients plus anticorrosion agents containing 0.4 to 80% benzotriazole, its ammonium salt, or tetrabortate, or their mixtures. The amount of the agent in the antifreeze is sufficient to produce a concentration of about 0.01 to 2.0% benzotriazole or its salt and 0.5 to 3.0% of the weight of the water soluble alcohols.

Another antifreeze consists of a water-soluble alcohol, particularly ethylene glycol, and an agent containing 0.2 to 77% benzotriazole, its alkali metal or ammonium salt or their mixtures, or N-alkylbenzotriazole; 2.2 to 80% of an alkali metal arsenite, arsenate or molybdate or their mixtures; and 11 to 96% of a material which maintains the pH of the aqueous solution of the anticorrosion agent at about 7.5 to 10.5.  The anticorrosion agent is present in an amount sufficient to produce concentrations of 0.01 to 2.0% benzotriazole; 0.1 to 2.0% arsenite, arsenate, or molybdate; and 0.5 to 2.5% of the buffer.

Other corrosion inhibitors for ethylene glycol solutions have been proposed. For example, one contains 1 part phosphoric acid (density 1.75) and sufficient technical triethanolamine (usually about 3 parts by wt) added to 100 parts ethylene glycol to bring the pH of a 50% aqueous solution of the mixture to 7.2. The resulting composition shows less tendency to corrode metals than a corresponding composition in which the benzotriazole is replaced by 0.2 to 0.3 parts sodium mercaptobenzotriazole.
