Sentinel R200 - Solar Cleaning Solution

Sentinel R200 - Solar Cleaning Solution Ready-to-use cleaner for solar heating systems Sentinel R200 Features and Benefits • Ready to use - no need for dilution • Removes sludge and deposits from degraded thermal fluid • Cleans with only 20 minutes circulation • Effective at low or room temperature • Can be used with flushing machine • None foaming and easy disposal • Compatible with the construction materials of the solar system 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.
