BVV™ Duratherm G Thermal Fluid - High Temp Rated 260°C (500°F) 1 Gallon

Struggling with oxidation, breakdowns & thermal inefficiency?

Duratherm G is here to end your high-heat fluid problems. This premium glycol-based thermal fluid runs clean at extreme temperatures up to 500 °F (260 °C), outperforming standard mineral oils and prolonging system life under demanding conditions.

🔥 Key Benefits

• Rated up to 500 °F (260 °C) — keeps performance steady under heat stress
• High flash point of 480 °F (249 °C) = enhanced safety and stability
• Engineered for oxidation resistance—perfect for open-bath systems
• Polyalkylene glycol formula reduces deposits & extends clean cycles
• Low volatility minimizes evaporation and fluid loss
• Maintains viscosity across temperatures—consistent heat transfer
• Helps extend equipment life & reduce maintenance downtime

How It Works

Unlike basic oils, Duratherm G uses a proprietary glycol blend and anti-oxidant additives, designed to resist film breakdown up to 550 °F (288 °C). It stays stable even during intense temperature swings, ensuring cleaner, longer-lasting operations and more efficient system performance.

Use Cases & Who It’s For

• Industrial processors & chemical manufacturers needing reliable open-bath heat transfer.
• Equipment operators in autoclaves, ovens, and thermal systems running ≥460 °F.
• Maintenance teams looking to reduce fluid replacements & prevent oxidation fouling.
• Design engineers who need a safe, high-performance fluid with minimal volatility.
