Why Oil Cooling for 500 KVA Applications?

Superior technology for ultra-heavy industrial applications

1

Superior Heat Management

Oil cooling provides 5x better heat dissipation than air cooling, maintaining optimal temperature even during continuous 24/7 ultra-heavy industrial operations.

2

Extended Lifespan

Reduced thermal stress extends component life to 15-20 years, compared to 8-12 years for air-cooled units in demanding ultra-heavy industrial environments.

3

Minimal Maintenance

Oil acts as natural insulator and coolant, reducing maintenance frequency by 70% compared to air-cooled stabilizers in demanding ultra-heavy industrial environments.

4

Enhanced Protection

Complete protection against dust, moisture, and environmental contaminants with IP54-56 rating, ideal for harsh ultra-heavy industrial conditions.

5

Silent Operation

No noisy fans means quieter operation, making it suitable for indoor installation in massive manufacturing plants and industrial facilities.

6

Better Performance

Consistent performance even in high ambient temperatures (up to 50°C) without derating, ensuring reliable power protection for critical ultra-heavy operations.

Oil Cooled vs Air Cooled: Ultra-Heavy Industrial Comparison

Parameter 500 KVA Oil Cooled 500 KVA Air Cooled
Heat Dissipation Excellent (5x better) Limited
Expected Lifespan 15-20 years 8-12 years
Maintenance Interval Every 2-3 years Every 6-12 months
Noise Level Silent operation Significant fan noise
Dust Protection Complete protection Dust accumulation issues
High Temp Performance Excellent (up to 50°C) Reduced efficiency
Initial Investment 20-25% higher Lower
10-Year Cost Lower (maintenance + lifespan) 45% higher
Indoor Installation Ideal for indoor Not recommended
Industrial Insight: For 500 KVA applications with 24/7 operation, oil cooled stabilizers provide 45% better long-term value despite 20-25% higher initial investment. The reduced maintenance and longer lifespan significantly lower total cost of ownership for ultra-heavy enterprise applications.
