Comes in 25KG drum (Liquid chemical)
COOLGUARD 401 is an alkaline blend of inorganic and organic scale and corrosion inhibitors. The product is stable over a wide range of temperature and pH variations and provides scale and corrosion control over a wide range of water qualities and operational conditions.
Open evaporative recirculating cooling water systems.
The dosage rate required is given by the following:
Dosage (m/m3 of make-up) = Reserve required in recirculation
Reserve required in recirc conc factor = 100ml/m3
Concentration factor = 5
Dosage required (ml/m3) = 100ml/m3 / 5 (cf)
Dosage required = 20ml/m3 of make-up
It is recommended at start-up and after system upset the product be dosed at 3 times normal dosage for a period of a week to promote rapid passivation.
|Inhibitor||pH||Calcium Hardness||Temporary Calcium Hardness||Inhibitor Concentration||Application Notes|
|Coolguard 185X||7.5 - 9.5||300 - 600||200 - 600||100ml/m3 min||Scale Inhibitor that requires a reasonable Temporary Calcium Hardness level to act as a corrosion inhibitor. Not suitable for use with continuous chlorination/bromination.|
|Coolguard 401||6.5 - 9.5||300 max||300 max||100 - 200ml/m3||Whilst product can be used at up to 600 Calcium it is recommended it be limited to 300 and an out and out scale inhibitor be used for higher levels|
