Closed System Chemicals

Closed circuits and closed loops that employ water as a primary medium are used extensively in many commercial, manufacturing and industrial process activities.

To ensure that such closed circuit systems are well maintained and operate at optimum efficiency it is essential that the correct water conditions are maintained at all times. This can be achieved using carefully selected closed circuit water treatment chemicals.

Accepta’s advanced technology closed loop and closed circuit treatment chemicals have been scientifically formulated to deliver significant operational benefits and performance improvements to closed loops and closed circuit systems including sea water cooling systems, closed chilled systems, low pressure heating systems and other closed circuits that use water as a primary medium.

Our extensive range of high performance closed loop treatment chemicals include anti-foulants, specific corrosion inhibitors, multi-functional scale and corrosion inhibitors, and anti-freeze and de-icing products for frost protection applications... closed circuit treatments >>

Corrosion Inhibitor for Closed Circuits Containing Aluminium

Accepta 2309 is a high performance corrosion inhibitor developed for closed water circulating systems containing aluminium.

Accepta 2309 is a corrosion inhibitor based on a novel blend of organic and inorganic corrosion inhibitors, including molybdate, intended to protect steel, copper and other non-ferrous metals. As such it is an ideal treatment for closed chilled water and low pressure heating systems.

Important- Whilst Accepta 2309 is designed to protect systems which incorporate aluminium it should NOT be used in systems with Stelrad Super Plus Modular boilers where an alternative product COPAL should be used, and in all applications where aluminium is present it is important to control the pH in the range 7 - 8.

Product Benefits

  • Excellent protection for systems which incorporate aluminium
  • High performance corrosion inhibitor
  • Protects steel, copper and other non-ferrous metals
  • Ideal treatment for closed chilled water and low pressure heating systems

Product Properties

Form: Aqueous solution
Colour: Brown
Odour: Mild
pH: 7.0 - 9.0
Water solubility: Soluble
Relative density: 1.0 - 1.1

Application & Dosage Information

For systems containing no aluminium Accepta 2309 should be dosed at 0.5 to 1% (5,000 -10,000 ml/m3) in order to give a reserve of 50ppm of sodium molybdate.

For systems containing aluminium the dosage of 1-1.5% should be added in order to maintain a minimum reserve of 100ppm of sodium molybdate. In certain circumstances it may be necessary to adjust the pH separately by the addition of a pH conditioner product.

In systems requiring significant passivation, higher initial dosages may be required to yield the required inhibitor residual.

Anti-Foulants

anti-foulants-for-closed-circuit-systems

The accumulation of microbiological slimes, biofilm and general bio-fouling in closed circuit water systems can be problematic. The build-up of such unwanted foulants can reduce system efficiency, and increase operating and maintenance costs.

To ensure that such closed circuit systems are well maintained and operate at optimum efficiency it is essential that the correct water conditions are maintained at all times. This can be achieved using carefully selected antifoulants designed specifically for such closed systems.

Accepta’s high performance antifoulants are ideal for use in closed loops and closed circuit systems that use water as a primary medium. They are scientifically formulated to efficiently remove and disperse unwanted microbiological fouling and slimes.

Accepta's closed circuit antifoulants aid system efficiency, optimise operating and maintenance costs, and minimise system shut-down periods... anti-foulants >>

Corrosion Inhibitors
