Houghton Chemical’s Heat Transfer Fluids Team is pleased to offer a free Standard Glycol Analysis Program designed to help customers maintain proper freeze protection, corrosion protection, and long-term system performance in hydronic and process cooling systems utilizing heat transfer fluids.
Routine glycol analysis is an important part of preventative maintenance and can help identify fluid degradation, contamination, inhibitor depletion, improper dilution, and other conditions before they lead to reduced system efficiency, equipment damage, or costly downtime. Regular testing can also help extend fluid life, reduce maintenance costs, and improve overall system reliability.
Standard Glycol Analysis Includes
- Glycol type identification
- Glycol concentration (% glycol)
- Freeze point determination
- pH analysis
- Reserve alkalinity testing
- General fluid condition comments
- Service recommendations based on analysis results
Additional extensive testing options are also available for systems requiring advanced analysis, contamination testing, inhibitor evaluation, or troubleshooting support.
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.
