Sentinel R500

Ready to use heat transfer fluid for ground source heat pump systems. To provide exceptional thermal transfer with superior stability and protection against corrosion and deposits as well as resistance to degradation, ground source heat pumps should be filled with R500 Thermal Fluid.



  • Ground source heat pump systems


  • Provides optimal freeze protection. Ready to use with built in freeze protection down to -22℃.
  • Superior corrosion and scale inhibition. Prolongs system life by protecting all metals commonly found in heat collector circuits from corrosion and deposits.
  • Chemically and thermally stable components. Resists degradation to extend fluid life and thereby reduces cost of system operation.
  • Safe to use. Based on propylene glucol; non-toxic and biodegradable.
