SENTINEL® R100
A superior heat transfer fluid for enhanced system performance and longer life, Sentinel R100 Heat Transfer Fluid is easy to use and is effective straight from the container. It is resistant to degradation and provides continuous protection against corrosion in both liquid and vapor states.
Sentinel R100 is designed for use in solar heating equipment operating up to 390°F. During static conditions the solar collectors should be completely empty so that the thermal fluid is not exposed to extreme temperatures.
Exposure to temperatures greater than 390°F, even for short periods of time, may lead to a slow thermal decomposition of the propylene glycol. This process, which is indicated by a darkening of the fluid, will reduce the lifetime of the thermal fluid.
Sentinel R100 must not be mixed with other heat transfer fluids, and must not be diluted with water. The heat transfer fluid in the system must only be replenished with Sentinel R100.
