Advanced Radiator Coolant & Corrosion Inhibitor for Locomotive Engines



HP POWERKOOL RR is a new generation Radiator Coolant and Corrosion Inhibitor, specifically developed for Indian Railways. Unlike the conventional anti-freeze radiator coolants, HP Powerkool RR is based on Organic Acid Technology and hence, it has the potency of giving prolonged service life.

Performance benefits:

  • Bio-degradable and environment friendly (being of Carboxylate base and boron free)
  • Exemplary corrosion inhibition of the metal components
  • Superior compatibility to Elastomers (rubber components) used in cooling system
  • Retention of concentration over a long duration, hence nil or negligible consumption (apart from those owing to leakage/ contamination etc.)
  • Low dosage requirement (only @ 3% with DM/Raw Water)


HP POWERKOOL RR is approved by RDSO for their EMD & ALCO Locomotives running all across the country.


HP POWERKOOL RR is recommended to be used @ 3% dosage with De-mineralized Water. The product also performs well with Raw Water.
