DOWCAL™ Geo-100 Heat Transfer Fluid

What is DOWCAL™ Geo-100 Heat Transfer Fluid?

An ethylene glycol-based geothermal fluid developed to provide improved performance and safety for geothermal heat pumps. DOWCAL™ Geothermal Fluids were designed to overcome the drawbacks of alternative fluids, providing greater assurance that geothermal systems will repay their initial investment costs in energy savings and in years of reliable, safe, and economical operation.

Uses

Ground source heat pumps

Benefits

Included on positive list of LAWA (German Working Group on water issues of the Federal States and the Federal Government represented by the Federal Environment Ministry)
Free of borate, nitrate, and CMR (Carcinogenic, mutagenic, and reprotoxic) classified substances
Nonflammable. When diluted in water at recommended concentrations, no measurable flash points. No fire hazard compared to alcohol-based fluids.
Efficient heat transfer. Changing from alcohol-based fluids to DOWCAL™ Geothermal Fluids will likely have no measurable impact on overall system heat transfer efficiency (individual fluid coefficients differ)
Reliable corrosion control. Dow signature corrosion inhibitors to protect metals. (Advantage over methanol, water, or uninhibited glycols)
Can be diluted to a 20% concentration while maintaining Pumping Efficiency and providing Corrosion Protection
