GeoSafe®
Geothermal Fluid
DESCRIPTION
GeoSafe® is a ethyl alcohol based fluid, specifically formulated for geothermal systems. In colder climates an antifreeze fluid is required to offer freeze protection and still provide a high level of heat transfer capability.
GeoSafe® is that fluid.
GeoSafe® is made from renewable ethyl alcohol with a proven inhibitor package to provide the added benefit of corrosion protection as well as freeze point depression. Although not toxic it has a bittering agent to render it unpalatable by humans and animals.
GeoSafe® is available as a full strength, un-diluted fluid or as a 25% premixed solution GeoSafe® 25. The premixed product is diluted with water meeting the following minimum requirements:
Calcium Carbonate 100ppm (max.)
Calcium 50ppm (max.)
Magnesium 25ppm (max.)
Chloride 40ppm (max.)
Sulfate 100ppm (max.)
GeoSafe® is safe for all geothermal systems. Although there may be some states that do not allow its use. In those cases we recommend the use of SAFE-T-THERM® our food grade inhibited propylene glycol product.
