The Hydro-Therm series, particularly Hydro-Therm PG100, is a propylene glycol-based heat transfer fluid designed for maximum freeze protection in various closed-loop water systems.
Base Fluid: 70% propylene glycol
Inhibitors: Food-grade corrosion inhibitors
Applications: Hydronic heating, chillers, solar heating, and other closed-loop water systems
Freeze Protection: Protects down to -60°F (-51°C)
Burst Protection: Up to -100°F (-73°C)
Corrosion Protection: Contains a food-grade corrosion inhibitor package specially designed for HVAC systems
Non-Toxic: Made with GRAS (Generally Recognized As Safe) ingredients
System Preparation: Thoroughly clean the system.
System Capacity: Measure the system capacity in gallons by filling completely with fresh water, draining into a suitable container, and recording the gallons removed.
Concentration Calculation: Select the desired temperature protection level and calculate the amount of PG100 required:
System Filling: Fill the system, ensuring all air is removed.
Testing: Use PG100 Test Strips to determine adequate freeze and corrosion protection.
Annual Retesting: Retest annually.
1 Gallon (H-801): Suitable for small systems or top-ups.
5 Gallon (H-805): Ideal for medium-sized systems.
55 Gallon Drum (H-855): Best for large systems or bulk applications.
