Cermax Ceramic Hydraulic Oil AW46 — STM-3 Nano Silicon Carbide Technology | Triple Protection for Hydraulic Systems
Stop hydraulic system failures before they start. Cermax Ceramic Hydraulic Oil AW46 is the only hydraulic fluid engineered with Cerma STM-3 Nano Silicon Carbide (SiC) technology — delivering triple protection against wear, deposits, and emissions while actively treating and sealing the metal components inside your hydraulic pumps, cylinders, and valves. Standard AW46 hydraulic oils simply lubricate. Cermax goes further: its SiC ceramic technology permanently bonds to metal sub-surfaces, reducing operating temperatures, extending pump life, preventing seal failures, and eliminating pump cavitation and air lock. The result is longer oil life, fewer breakdowns, reduced maintenance costs, and hydraulic systems that run cooler, smoother, and more reliably in any climate. Available in quart, gallon, case, pail, and drum sizes for any operation.

🔬 Why Cermax Hydraulic Oil Outperforms Standard AW46
Conventional AW46 hydraulic oils rely solely on anti-wear additives that deplete over time. Cermax is fundamentally different. Its STM-3 technology applies a permanent Nano Silicon Carbide (SiC) matrix seal within the metal sub-surfaces of pumps, cylinders, and valves. SiC has a Mohs hardness of 9.5 (nearly as hard as diamond) and a melting point of 2,730°C. This ceramic bond doesn’t deplete — it actually strengthens over time, continuously treating and sealing metal components. The result: dramatically reduced wear, lower oil temperatures, eliminated cavitation, extended pump life, and hydraulic oil that lasts far longer than conventional fluids.
⚙️ How STM-3 Technology Solves Common Hydraulic Problems
| Common Hydraulic Problem | How Cermax AW46 Solves It |
|---|---|
| Oil overheating & thermal breakdown | SiC reduces friction at metal surfaces → lower operating temperatures → longer oil life |
| Pump cavitation & air lock | Reduced air content in oil eliminates cavitation damage and prevents air lock in pumps |
| Seal failures & leaks | STM-3 treats and seals metal components, reducing seal degradation and extending seal life |
| Unstable ram & cylinder control | Consistent viscosity and sealed components provide stable, precise control |
| Moisture contamination & corrosion | Superior moisture reduction + SiC ceramic barrier protects against water damage and rust |
| Sluggish cold-weather performance | Improved cold-weather flow ensures reliable startup and operation in freezing conditions |
| Frequent oil changes & high maintenance costs | Longer-lasting oil + reduced wear = fewer changes, less downtime, lower total cost |

📋 How to Use Cermax AW46 Hydraulic Oil
- Check System Requirements: Verify your hydraulic system specifies AW46 (ISO VG 46) hydraulic oil. Most standard hydraulic systems use AW46.
- Drain Old Oil: Drain existing hydraulic fluid from the reservoir. Replace the hydraulic filter if applicable.
- Fill with Cermax AW46: Add the correct volume of Cermax Ceramic Hydraulic Oil AW46 to the reservoir.
- Cycle the System: Run the hydraulic system through its full range of motion several times to circulate the new oil through all lines, cylinders, and valves.
- Check Level: After cycling, recheck the reservoir level and top off if needed.
- Ongoing: The STM-3 SiC technology will begin bonding to metal surfaces immediately. Benefits increase over the first hours of operation as the ceramic matrix fully establishes.
💡 For Maximum Protection:
For systems requiring additional ceramic treatment, consider adding Cerma Ceramic Hydraulic Treatment to your hydraulic system. The dedicated treatment creates a deeper initial ceramic bond, and Cermax AW46 oil then maintains and reinforces it over time.

❓ Frequently Asked Questions
What makes Cermax AW46 different from standard hydraulic oil?
Cermax AW46 contains STM-3 Nano Silicon Carbide (SiC) technology — a ceramic compound nearly as hard as diamond (Mohs 9.5). Unlike standard AW46 oils that only lubricate, Cermax permanently bonds a ceramic matrix to the metal surfaces inside your hydraulic pumps, cylinders, and valves. This ceramic bond reduces operating temperatures, prevents cavitation, extends seal life, and provides moisture protection that conventional hydraulic oils simply cannot match.
How does Cermax AW46 reduce hydraulic system temperatures?
The SiC ceramic bond reduces friction at every metal-to-metal contact point inside the hydraulic system. Less friction = less heat generated = lower operating temperatures. Lower temperatures mean the oil degrades more slowly, extends its useful life, reduces the risk of thermal breakdown, and prevents the overheating that causes system failures and unplanned downtime.
What does “reduced pump cavitation” mean and why does it matter?
Cavitation occurs when air bubbles form in hydraulic oil and then collapse violently against metal surfaces, causing pitting, erosion, and noise. It’s one of the leading causes of hydraulic pump failure. Cermax AW46 reduces air content in the oil, preventing cavitation from occurring and eliminating the “air lock” conditions that can cause pumps to lose prime and fail. This extends pump life significantly.
Can I use Cermax AW46 in cold weather?
Yes. Cermax AW46 is specifically engineered for improved cold weather operation. It maintains proper viscosity and flow characteristics in cold temperatures, ensuring reliable hydraulic performance during winter operation, cold starts, and in equipment that operates in freezing environments like snow plows, logging equipment, and northern construction sites.
Is Cermax AW46 compatible with my equipment?
Cermax AW46 is compatible with any hydraulic system that specifies AW46 (ISO VG 46) hydraulic oil — which includes the vast majority of construction equipment, agricultural machinery, industrial hydraulics, material handling equipment, marine hydraulic systems, and more. Always verify your equipment manufacturer’s hydraulic fluid specification before use.
Do I also need the Cerma Hydraulic Treatment?
Cermax AW46 provides significant SiC ceramic benefits on its own. For maximum results in heavily worn or critical systems, adding Cerma Ceramic Hydraulic Treatment first creates a deeper initial ceramic bond that Cermax oil then maintains. The treatment is a one-time application, while Cermax AW46 is your ongoing hydraulic oil for all subsequent fills.
How often should I change Cermax AW46?
Follow your equipment manufacturer’s recommended hydraulic oil change interval. Because Cermax AW46 runs at lower temperatures and resists degradation better than standard oils, you may find the oil maintains its properties longer. We recommend periodic oil analysis to determine the optimal change interval for your specific application and operating conditions.
Can I mix Cermax AW46 with my existing hydraulic oil?
For best results, we recommend draining the existing hydraulic oil and filling with Cermax AW46. This ensures the SiC technology can work at full effectiveness without dilution. However, Cermax AW46 is compatible with standard AW46 hydraulic oils and can be added to existing fills if a complete change is not immediately practical.
