Laboratory Analysis to Monitor Fluid Condition, Corrosion, and System Performance
Dynalene provides comprehensive laboratory testing for heat transfer fluids used across a wide range of applications, including industrial cooling systems, HVAC systems, process cooling equipment, and advanced liquid cooling systems.
Over time, heat transfer fluids can experience chemical degradation, inhibitor depletion, contamination, and corrosion-related changes that affect thermal performance and equipment reliability. Dynalene’s testing programs help identify these changes early, allowing customers to make informed maintenance decisions and maximize fluid and system life.
Traditional Glycol-Based Heat Transfer Fluids
Glycol-Based Heat Transfer Fluid Testing
Dynalene offers a comprehensive quality control (QC) testing program for glycol-based heat transfer fluids used in HVAC systems, industrial loops, process cooling equipment, and other closed-loop thermal management systems.
Our laboratory analysis is designed to monitor fluid condition, detect early signs of degradation, and identify corrosion activity—helping maintain system efficiency, reduce maintenance costs, and extend fluid service life.
Our testing approach is based on established industry practices and utilizes proven analytical techniques aligned with applicable ASTM standards to evaluate key indicators such as inhibitor health, fluid stability, and system cleanliness.
Data Center Coolant (PG25) Testing
Dynalene offers a comprehensive quality control (QC) testing program for propylene glycol-based (PG25) coolants used in modern data center cooling systems, including direct-to-chip cold plates and Coolant Distribution Units (CDUs).
Our laboratory analysis is designed to detect early signs of fluid degradation, corrosion activity, and performance loss—helping prevent costly downtime and extend system life.
Our testing approach aligns with industry best practices and supports Open Compute Project (OCP) cooling guidelines, utilizing proven analytical techniques aligned with applicable ASTM standards.
Comprehensive Coolant Analysis
We evaluate the key chemical and physical indicators that define coolant health and system performance:
- Glycol Concentration (PG %)
- pH and Reserve Alkalinity (Buffering Capacity)
- Dissolved Corrosion Metals (iron, copper, aluminum, etc., measured at ppm levels)
- Inhibitor Condition (OAT/additive health)
- Glycol Degradation By-Products (organic acids and intermediates)
- Turbidity (fluid clarity and indication of suspended material)
All testing is performed using laboratory-grade techniques within a quality-controlled laboratory environment, including ICP-OES for metals analysis and titration-based methods for alkalinity and inhibitor evaluation.
How We Test Your Products
Routine coolant testing provides actionable insight into system condition and helps operators move from reactive maintenance to proactive system management.
pH & Reserve Alkalinity
Tracking pH, coupled with monitoring reserve alkalinity, provides a clear picture of the coolant’s remaining buffering capacity.
A decline in pH and reserve alkalinity signals weakening inhibitor protection and the formation of acidic degradation products. Identifying these trends early allows corrective action before significant metal degradation, component fouling, and expensive hardware damage.
Glycol Concentration
Proper glycol concentration ensures optimal thermal performance, viscosity, and freeze/boil protection.
Testing also identifies dilution, fluid loss, or mixing errors that may compromise system efficiency.
Metals Analysis
Trace-level increases in dissolved metals (ppm) are strong indicators of active corrosion within cooling infrastructure, including CDU components, distribution piping, cold plates, and heat exchangers.
Early detection enables corrective action before visible damage or performance loss occurs.
Glycol Breakdown Products
The analysis helps identify the formation of organic acids and breakdown intermediates signaling early-stage fluid degradation.
These by-products can lower pH and accelerate localized corrosion on critical components such as cold plates and manifolds.
Inhibitor Health
Monitoring inhibitor levels confirms the coolant continues to provide effective corrosion protection and helps identify underlying issues such as oxygen ingress, elevated temperatures, contamination, or other conditions that accelerate fluid degradation.
Why Routine Testing Matters
Maintaining coolant within recommended operating parameters is critical to reliable data center operation. Our testing program helps:
- Detect early signs of corrosion and fluid instability
- Maintain efficient heat transfer and stable flow
- Reduce fouling, scaling, and flow restrictions
- Minimize unplanned downtime and maintenance costs
- Extend the lifespan of both coolant and system components
Our Data Center Coolant testing program keeps systems operating at peak performance by ensuring the coolant is maintained within recommended OCP industry guidelines.
By verifying fluid condition, concentration, and inhibitor health, we help preserve efficient heat transfer, stable flow, and reliable corrosion protection. This service reduces the risk of fouling, corrosion, and flow restrictions that can strain equipment, trigger alarms, or lead to unplanned downtime, while extending the life of both the fluid and critical system components.
