Accepta 0503 is a high performance, low toxicity, environmental friendly, multi-metal corrosion inhibitor developed for use in closed circuit hot water and chilled water systems.
Accepta 0503 is a neutral inhibitor suitable for multi-metal systems including aluminium and aluminium alloys.
If a neutral environment is required, Accepta 0503 should be considered as the preferred inhibitor.
Accepta 0503is compatible with ethylene and propylene glycol solutions.

Application & Dosage Information
For mild steel/copper systems Accepta 0503 should be dosed at 1% of the system volume, equivalent to 10 litres per m3 to give approximately 100 -120 of molybdate as MoO4.
For multi metal systems containing aluminium Accepta 0503 should be dosed at a minimum of 1.5 – 2% of the system volume, equivalent to 15 – 20 litres per m3, to give approximately 150 to 200 ppm of molybdate as MoO4.
New systems should be pre-commission cleaned prior to dosing.
Accepta 0503 is normally added via a dosing pot or a positive displacement pump..
It is always advisable to carry out a ‘Control Of Substances Hazardous to Health’ (COSHH) assessment before use.
