Lubrication applications in the steel industry are some of the most challenging ever.
Plants work under extreme conditions, where high temperatures, risk of fire, high loads, and the presence of water or pollutants constantly test the endurance of hydraulic fluids.
Thanks to decades of experience, CONDAT has developed a range of fire-resistant lubricants and hydraulic fluids recognized for their high level of engineering and responsiveness to the extreme demands of the steel industry.
Hydraulic fluids from the CONDAT range are used:
- in the steel mills: electric furnaces, ladle furnaces, continuous casting;
- On hot rolling lines: stand hydraulics;
- in cold rolling mills, where system cleanliness and stability are critical.
Condat D 46: fire resistant HFDU hydraulic fluid
The Condat D 46 is a synthetic, nonaqueous hydraulic fluid belonging to the Hydraulic Fluid Dry, Unflammable (HFDU) category.
It is a self-extinguishing ester-type fluid designed for use in high-pressure hydraulic systems where protection against fire hazard is required.
Formulated with synthetic polyether polyol bases and high-performance additives, Condat D 46 combines excellent anti-wear and anti-corrosion properties with good filterability and effective air release, contributing to the cleanliness andefficiency of the hydraulic system.
The characteristics of Condat D 46 hydraulic fluid
- Fire resistance: the fluid is self-extinguishing and has a high flash point, ideal for environments where fire risk is high.
- Biodegradability and environmental safety: complying with OECD 301B, it is biodegradable and non-toxic to operators and the environment.
- High oxidation stability: maintains its performance over time, extending the service life of hydraulic fluid and reducing the frequency of oil changes.
- Excellent lubrication: ensures the protection of pumps, motors and valves, reducing wear and tear on hydraulic components.
- Excellent filterability and deaeration properties: helps maintain a cleaner and more stable hydraulic system.
- High viscosity index: ensures constant viscosity as temperature changes, avoiding pressure variations and efficiency losses.
- Material and gasket compatibility: it is miscible with hydraulic mineral oils and compatible with most commonly used metals and gaskets.
- Low pour point: allows hydraulic fluid to be used even in cold environments or changing climatic conditions.
Condat D 46 certified FM Global
Condat D 46 is FM Global certified, one of the world’s most recognized organizations in industrial risk prevention.
FM Approvals certification attests that the hydraulic fluid has passed rigorous fire resistance and quality tests, ensuring compliance with the strictest international standards.
Using an FM Approved fluid means reducing fire risks, protecting operators and facilities while ensuring operational reliability and safety.
Alongside FM Global, the Condat D range also includes products certified by MSHA (Mine Safety and Health Administration), the U.S. agency that regulates safety in underground work. These include the Condat D 68.
Performance and operational advantages of Condat D hydraulic fluids
CONDAT D fire-resistant hydraulic fluids fully meet the requirements of ISO 12922, which defines safety and performance standards for HFDU fluids.
