Industrial Strength Acidic Detergent Pipe-Work Cleanser. Especially formulated to neutralise, suspend and remove surface rust and mineral scale deposits within cooling and heating systems.

Purachem HSC2 is a blend of phosphoric acid, wetting agents and water to suit the strength required.


Function

Purachem HSC2 can be used as a pre- commission pipe-work cleanser. It is ideal for use when implementing a chemical cleaning policy, such as BSRIA BG 29/2012.

Purachem HSC2 is suitable for use in a wide range of heating and cooling systems.

Purachem HSC2 can be used to help restore corroded and furred-up systems to their original condition. For example when;

Utilisation

Purachem HSC2 can be supplied in concentrate and in dilute form. The standard concentration requires 25 litres per 1000 litres of system volume. At this strength most contaminated systems can be cleansed in a single operation.

The following procedure, applied in conjunction with the appropriate engineering methods,* will maximise the capabilities of Purachem HSC2

  1. Drain existing system contents. Be sure to empty all ‘dead-legs’ and open any vents to ensure total drainage.
  2. Refill with fresh water and the appropriate volume of Purachem HSC2 (see above).
  3. Vent the system of any trapped air.
  4. Recirculate for a minimum of two hours and a maximum of 24 hours. Regularly check all filters and clean as necessary.
  5. Repeat 1.
  6. Refill with fresh water.
  7. Repeat 3.
  8. Recirculate for one hour and then take a sample. Test sample to confirm all biological contaminants have been neutralised.
  9. Repeat 1.
  10. Refill with required strength of inhibited heat transfer fluid and good quality fresh water.
  11. Repeat 3.
  12. Re-commission the system and take a second sample for detailed lab analysis. Please refer to the SureFlow Fluid Maintenance Program for more information on sample testing and reports.
