Fire-Resistant Hydraulic Fluids for the Forestry and Timber Industry
FRAGOL HFDU BIO 46 und 68 - With biodegradable* polyol ester

Forest, people and machinery in focus
When hydraulic fluids are used in sensitive ecosystems and at the same time exposed to an elevated fire risk, conventional solutions are often inadequate. Our fire-resistant and simultaneously biodegradable* hydraulic fluids, FRAGOL HFDU BIO 46 and 68, combine high safety standards with active protection:
• Synthetic high-performance hydraulic fluids based on polyol ester (POE)
• Biodegradability in accordance with OECD 301 B*
• Fire-resistant…
... meets the requirements of Factory Mutual (FM),
... meets the requirements of MSHA (Mine Safety and Health Administration)
• Flash point (COC) > 300 °C
• Auto-ignition temperature > 350 °C
The hydraulic fluids FRAGOL HFDU BIO 46 and 68 are therefore ideally suited for use in the forestry and timber industry, where every leak and every spark can have serious consequences. They help protect both personnel and machinery, reduce operational risks, and make an important contribution to preserving valuable forest resources.
Engineered for Demanding Applications
Forestry machines such as harvesters and forwarders operate under extreme conditions and are therefore subject to considerable mechanical stress. In addition to the benefits of biodegradability and fire protection outlined above, FRAGOL HFDU BIO 46 and 68 ensure reliable machine performance:
- Contains ash-free and silicone-free additive technology
- No deposits or varnish formation
- Suitable for use across a wide operating temperature range
- Fewer oil changes compared with mineral oil-based products
- Meets the requirements of ISO 12922 (HFDU)
- Meets the requirements of ISO 15380 (HEES)
