Houghton Chemical’s Heat Transfer Fluids Team is pleased to offer an Extensive Glycol Analysis Program designed to provide a more detailed evaluation of heat transfer fluid condition, system health, and long-term performance. Extensive analysis can help identify early signs of fluid degradation, corrosion activity, contamination, and inhibitor depletion before they lead to reduced system efficiency, equipment damage, or costly downtime.
The Extensive Glycol Analysis Program is commonly used in critical HVAC systems, data center cooling systems, geothermal systems, industrial process cooling applications, food and beverage processing systems, and other closed-loop heat transfer systems where fluid condition and operational reliability are especially important.
Extensive Glycol Analysis Includes
- Glycol type identification (if necessary)
- Glycol concentration (% glycol)
- Freeze point determination
- pH analysis
- Reserve alkalinity testing
- General fluid condition comments
- Service recommendations
- Inhibitor level evaluation
- Corrosion product analysis
- Degradation product analysis
- Contaminant identification and evaluation
Extensive analysis provides a more complete understanding of system condition and can help support preventative maintenance planning, fluid life extension, troubleshooting efforts, and long-term system reliability.
Houghton Chemical also offers re-inhibitor formulations designed to help restore corrosion protection and extend fluid life in systems experiencing inhibitor depletion. Re-inhibitors are available for both propylene glycol and ethylene glycol-based heat transfer fluids, including SAFE-T-THERM® and WINTREX® product lines.
Sampling Instructions
Proper sampling procedures are important to ensure accurate analysis results. Houghton Chemical recommends the following sampling guidelines:
- Allow the system fluid to circulate for a minimum of 24 hours prior to collecting the sample.
- Collect the sample from a circulating section of the system whenever possible. Avoid stagnant areas, low points, or drain locations where debris may accumulate.
- Use a clean sample container provided by Houghton Chemical or a clean plastic bottle with a secure cap.
- Fill the container with approximately 4 ounces of fluid.
- Clearly label the sample with:
- Company name
- Contact information
- System location or identification
- Fluid type (if known)
- Date sample was collected
- Submit the sample to Houghton Chemical for laboratory analysis.
