Actual system operating limits depend on concentration, equipment design, pressure, circulation conditions and the specific thermal system. 

6. What is the recommended concentration of ORA100 Heat Transfer Fluid?

For corrosion protection, the reference information recommends a minimum concentration of approximately 30% for the applicable system conditions.

Other technical documentation indicates that lower concentrations may be suitable for particular temperature ranges and applications. Therefore, the correct concentration should be calculated according to the required freezing point and system operating conditions. 

7. What is the freezing point of a 50% solution?

A 50% by volume solution in demineralized water has a reference freezing point of approximately:

-38°C

This value is a typical technical value and should not be treated as a universal specification for every RXSOL batch.

RXSOL-81-1587-211 ORA100 is supplied as a clear/colorless liquid based on the referenced technical information.

9. What is the density of ORA100 Heat Transfer Fluid?

The reference technical data gives a typical density of approximately:

1.135 g/cm³ at 20°C

The acceptable commercial specification should be confirmed against the RXSOL batch COA. 

10. What is the pH of ORA100 Heat Transfer Fluid?

For a 50% volume solution in demineralized water, the reference pH is approximately:

7.6–8.2

This represents the typical technical value of the referenced inhibited glycol formulation. 

11. Does ORA100 ORA100 Heat Transfer Fluid provide corrosion protection?

Yes. ORA100 is an inhibited glycol-based heat transfer fluid, formulated with performance additives intended to provide corrosion protection in compatible thermal systems.

Particular attention is given to corrosion protection of aluminum alloys in the reference formulation. 

12. Can ORA100 ORA100 Heat Transfer Fluid be used with aluminum equipment?

ORA100 Heat Transfer Fluid is suitable for systems where corrosion protection of aluminum alloys is required, subject to compatibility with the complete system.

Before filling a new or existing installation, compatibility should be checked for:

18. Does ORA100 Heat Transfer Fluid prevent freezing?

ORA100 itself is a concentrated glycol-based heat-transfer fluid. When properly diluted, it lowers the freezing point of the circulating fluid.

The level of freeze protection depends directly on the final glycol concentration. A 50% volume solution in the referenced formulation has a typical freezing point around -38°C. 

19. Is ORA100 Heat Transfer Fluid water soluble?

Yes. Ethylene glycol is completely miscible with water, allowing the concentrate to be diluted to the required operating concentration.

For best system performance, use water of appropriate quality, preferably demineralized/deionized where system requirements call for it.
