Designed for use as a thermal fluid in solar heating equipment such as flat plate and vacuum tube collectors, Sentinel R100 Solar Thermal Fluid is ready-to-use, making it a convenient product for enhancing system performance and prolonging its life span.

Sentinel R100 Solar Thermal Fluid is easy to use and is effective straight from the container. Not only does it have efficient thermal transfer properties and superior resistance to degradation, it also provides frost protection down to -25°C. All of these attributes prolong the working life of the system and help towards reducing the cost of operation. 

Sentinel R100 Solar Thermal Fluid is glycol-based and designed for use in solar heating equipment operating up to 200°C. 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 200°C, even for short periods of time, may lead to a slow thermal decomposition of the glycol. This process, which is indicated by a darkening of the fluid, will reduce the lifetime of the thermal fluid.

Sentinel R100 Solar Thermal Fluid 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 Solar Thermal Fluid.
