DOWCAL™ Inhibited Glycol Fluids/Coolants
DOWCAL™ Geothermal Fluids, ready-to-use glycol-based heat transfer fluids intended for geothermal heat pump systems. Both DOWCAL pGEO (propylene glycol-based) fluid and DOWCAL eGEO (ethylene glycol-based) fluid contain specially designed corrosion inhibitors that satisfy ASTM D1384 requirements. DOWCAL eGEO will not sustain bio-organism growth when used at full strength, but its lower glycol content gives it lower viscosity and higher heat transfer efficiency.
- Secondary cooling and heating
- Freeze, burst protection
- Renewable energy
- Ground Source Heat Pumps (GSHP)
- DOWCAL pGEO offers a low acute oral toxicity, reducing contamination hazards compared to methanol alternatives. DOWCAL eGEO and DOWCAL pGEO can be diluted to 20% concentration in order to provide corrosion protection while maintaining pumping efficiency.
