Properties
Sentinel R100 Solar Thermal Fluid is a clear blue liquid based on propylene glycol solution. It has been designed for use as a thermal fluid in solar heating equipment such as flat plate and vacuum tube collectors where it ensures highly efficient heat transfer between the solar collector and the thermal store. Sentinel R100 is also optimised to provide freeze protection of the circuit even to 25°C.
The special inhibitors contained in Sentinel R100 provide superior protection to the metals normally used in solar installations against corrosion and deposits. Sentinel R100 prevents the surfaces of heat exchangers fouling and maintains thermal efficiency. The product is especially formulated to resist thermal degradation and so extend fluid life.
The efficient thermal transfer properties and superior stability of Sentinel R100 help towards reduced cost of system operation.

Properties
Sentinel R200 is a specially formulated, mildly alkaline product designed for use as a cleaner for solar heating system circuits containing either flat plate or vacuum tube collectors.
The thermal fluids used in solar heating systems may degrade over time because of prolonged exposure to elevated temperatures.
This degradation process, which is indicated by a darkening of the fluid, not only reduces the lifetime of the thermal fluid, but also has the following adverse effects on the operation of the system:
Colour changes and viscosity increases
Thickening of the fluid and solid deposits which causes blockages
Reduces the diameter of the pipe work
Freezing point increases
pH decreases
The degraded fluid has a reduced heat transfer capability
In order to restore the efficient operation of the solar heating system it is necessary to drain the degraded thermal fluid, clean the system to remove any sludge, deposits or blockages, and refill the system with Sentinel R100 - a thermal fluid which is especially formulated to resist thermal degradation and so extend fluid life.
