DOWCAL™ GEO-200 Propylene Glycol
DOWCAL™ GEO-200 (previously DOWCAL™ pGEO) heat transfer fluid is a propylene glycol-based fluid intended for geothermal heat pump systems. The typical ground source heat pump (GSHP) will circulate the DOWCAL™ GEO-200 dilution through the geothermal coils using the earth's constant temperature to exchange hot air for cooler in the summer and cold air for warmer in the winter months.
DOWCAL™ GEO-200 is on the positive list of LAWA, meeting all requirements for new formulations.
DOWCAL™ GEO-200 (before DOWCAL™ pGEO) inhibited heat transfer fluid is a high performance solution for geothermal plants and ground source heat pump (GSHP) systems. DOWCAL™ GEO-200 is a propylene glycol (propane-1,2-diol) based solution that offers a reduced viscosity and increased thermal capacity & conductivity compared to alternative heat transfer fluids.
DOWCAL™ GEO-200 is available in green concentrate and a variety of packaging sizes. When diluted to a 20% concentration DOWCAL™ geothermal fluids provides corrosion protection while maintaining pumping efficiency.
DOWCAL™ GEO-200 is on the positive list of LAWA (German Working Group on water issues of the Federal States and the Federal Government represented by the Federal Environment Ministry), meeting all requirements for new formulations.
