Description
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.
Suitable for
Open evaporative recirculating cooling water systems.
Dosage Calculation
The dosage rate required is given by the following:
Dosage (m/m3 of make-up) = Reserve required in recirculation
Concentration factor
Example
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 |
