As vehicles evolve with hybrid and electric powertrains, coolant formulations face new thermal and chemical demands. The Analysis Instrument for Antifreeze Testing expands on basic freeze/boil tests by adding glycol durability, thermal cycling, and deposit analysis modules in a unified platform.
Freeze/Boil Cycles
Automates repeated freeze (–40 °C) and boil (135 °C) sequences to evaluate additive resilience.
Glycol Degradation
Monitors breakdown products via onboard refractometry and spectrophotometry after thermal aging.
Deposit & Sludge Formation
Circulates coolant through heated coils with metal coupons; measures deposit mass and composition.
Thermal Conductivity
Assesses coolant’s heat-transfer efficiency using a transient hot-wire probe.
Programmable Cycle Controller: Defines number of freeze/boil repetitions, dwell times, and ramp rates.
Inline Refractometer & UV Detector: Capture glycol concentration changes and organic by-products.
Flow-through Coil Module: Simulates engine channels with controlled flow rates and temperatures.
Data Integration: Correlates chemical, thermal, and deposit data in a unified dashboard.
Next-Generation Coolant R&D: Validate inhibitors for aluminum and mixed-metal engine blocks.
Electric Vehicle Thermal Management: Ensure stability in battery-coolant loops under variable loads.
Fleet Testing: Simulate extended service intervals and predict maintenance schedules.
Laboratory Method Development: Establish new standards for hybrid coolant performance.
Coolant Filtration: Filter samples through 5 µm media prior to deposit testing.
Probe Calibration: Standardize refractometer and conductivity probes with certified solutions bi-monthly.
Coupon Preparation: Polish and weigh metal coupons to ±0.1 mg before exposure.
Safety Measures: Use closed-loop fluid handling to prevent ethylene glycol vapor release.
