EnviChem 1680 SCALE AND CORROSION INHIBITOR

Description

EnviChem 1680 is a combination of organic and inorganic inhibitors, a strong dispersant containing polycarboxylic acid and a pH buffer system. EnviChem 1680 is free of chromates, nitrites and toxic heavy metals.

PRINCIPAL USES

EnviChem 1680 prevents corrosion and deposit formation in closed heating systems filled with softened or demineralized makeup water.
EnviChem 1680 is mainly applied in hot water boilers or heating systems like secondary heating systems of power plants and chemical industry as well as in closed heating loops of all types of industries.

PRODUCT BENEFITS

– Prevents corrosion on copper and its alloys
– Maintains constant heat transfer by keeping surfaces free of deposits
– Stabilizes pH range
– Prevents scale formation and resulting tube failures
– Provides metal passivation
– Environmentally friendly; does not contain heavy metals and inorganic phosphate

DOSAGE

The specific dosage of EnviChem 1680 varies depending on the operating characteristics (material of construction, holding time, water chemistry) of your system and the total acidified hardness of feed water. Important parameters (e.g. product concentration, hardness, pH) have to be kept and checked regularly. To control the performance of EnviChem 1680 treatment, a suitable analytical procedure as well as test-kits is available.
Your EnviChem representative will recommend the optimum dosage necessary to ensure maximum program performance according to your specific system parameters.
FEEDING
EnviChem 1680 is applied neat or diluted with softened or diluted water at any ratio. EnviChem 1680 should be fed to maintain a pH of 8.5 to 9.0 throughout the condensate system. This range is optimal for corrosion protection.
MATERIALS: Storage and application equipments (pumps, lines) should be made of plastic material, PE, PP, PVC, PTFE or stainless steel. Do not use carbon steel, copper, brass or aluminum in contact with the neat product.

HANDLING-STORAGE-SHIPPING

As a standard precaution with all chemicals we recommend the use of personal protective equipments such as goggles and rubber gloves when handling. Consult the Material Safety Data Sheet as the only official source of Environmental and Safety information.
EnviChem 1680 can be stored for at least 24 months from date of shipping if kept in its original, unopened container and under normal warehouse conditions. Protect from freezing and from exposure to high temperature.
EnviChem 1680 is available in non-returnable containers of different sizes.
