DOWCAL™ (Europe, Middle East, India & Africa only)

Dow's newest addition to the heat transfer fluid product line, 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. 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.

DOWCAL 100 is an ethylene glycol-based fluid used in a wide range of industrial, pharmaceutical, HVAC and heat recovery applications. It is an inhibited glycol that contains Dow Heat Transfer Fluids' specially formulated corrosion inhibitors that protect aluminum, copper, alloys, ferrous and other metals. DOWCAL 100 has improved performance and corrosion protection and is suitable for use at minimum 20% concentration for high and low temperatures.

DOWCAL N heat transfer fluid is a propylene glycol-based, is low in acute oral toxicity, and is widely used to depress freeze points in food and beverage processing and other applications. This fluid contains a specially formulated inhibitor package that helps prevent corrosion of common materials of construction in HVAC, food and beverage processing, and other systems. Suitable applications include: secondary cooling and heating in the food and beverage industry, freeze, burst and corrosion protection of pipes. It's also suitable for various deicing, defrosting, and dehumidifying applications in meat, poultry and other food processing applications.

DOWCAL 200 is a propylene glycol-based fluid capable of operating at higher temperatures than other propylene glycol fluids. This fluid is low in acute oral toxicity and contains a specially formulated inhibitor package that helps prevent corrosion of common materials of construction in HVAC, food and beverage processing, and other systems. Suitable applications include: single fluid process heating and cooling, closed-loop, water-based heating and air conditioning systems where propylene glycol-based fluids are preferred or required, food industry applications within temperature range.
