PG HD
HEAT TRANSFER FLUID
A ready-to-use virgin propylene glycol-based heat transfer fluid containing a specially designed inhibitor package that controls the corrosion of metals, helps prevent scaling and the fouling as evidenced by ASTM 8040 analysis and buffers the pH to assist in maintaining in the optimum operating range.
- Fluid is dyed fluorescent pink for leak detection purposes
- Available in dilutions ranging from 30% to 70%
- Silicate free
Product Overview
SOLUTHERM™ PG HD has operating temperature ranges from product freeze point up to 325°F (162.7°C) when mixed with appropriate water concentrations. It provides both freeze and burst protection for systems exposed to very low temperatures.
SOLUTHERM™ PG HD inhibited virgin propylene glycol-based heat transfer fluid is manufactured with proprietary inhibitor chemistry that helps prevent corrosion, which minimizes fluid expense and extends fluid life*. This product is silicate-free and meets Heat Transfer Fluid ASTM D8039 standard. Available in dilutions ranging from 30% to 70% PG.
Performance Features & Benefits
- Fluid is dyed fluorescent pink for leak detection purposes
- Silicate free
- Meets the Heat Transfer Fluid ASTM D8039 standard for multi-metal corrosion protection and foaming tendency for ready-to-use heat transfer fluids when a minimum of 30% is used
- Available in dilutions ranging from 30% to 70%
- Operating temperature of -60°F to 325°F (-51.1°C to 162.7°C)
