DOSAGE

The specific dosage of EnviChem 1121 varies depending on the operating characteristics of your system and the water chemistry.
EnviChem 1121 should be dosed in any case at a dosage enough to scavenge oxygen (50 ppm product/ppm 02) and to maintain a pH of minimum 8.3 in the condensate system.
Your EnviChem representative will recommend the optimum dosage necessary to ensure maximum program performance according to your specific system parameters.
FEEDING:
EnviChem 1121 is applied neat or diluted with demineralized water, condensate (<35oC ) or deaerated boiler feedwater via a stainless steel quill into the deaerators storage tank.
Recommended dosing point for EnviChem 1121 is the deaerator’s storage section in boilers.
MATERIALS: Storage and application equipments (pumps, lines) should be made of stainless steel or common plastic materials like PE, PP, PVC, EPDM, Teflon or Viton. Do not use carbon steel, brass or nickel 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 1121 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 1121 is available in non-returnable containers of different sizes.
