This model is engineered to handle severe moisture and temperature fluctuations, making it ideal for large power transformers, wind farm transformers, and outdoor high-humidity environments.

Key Features

• Dual-Chamber Double Breathing Design: Dual air-flow paths for balanced, high-efficiency dehumidification; reduces pressure loss and improves air circulation.
• Orange C5 Indicator Silica Gel: Eco-friendly, non-cobalt orange silica gel that changes to green when saturated (clear visual cue); safer than traditional blue cobalt-containing gel.
• Large Moisture Capacity: Extended silica gel chamber for longer maintenance intervals; suitable for continuous heavy-duty operation.
• Enhanced Oil Seal System: Double-layer oil cup design prevents oil splashing, backflow, and dust contamination; improves sealing stability.
• Robust Construction: Corrosion-resistant aluminum alloy or stainless steel housing; weatherproof (IP55) for long-term outdoor use.
• Easy Maintenance: Top-loading silica gel refill design; detachable oil cup for quick cleaning; no special tools required.
• Wide Temperature Adaptation: Stable performance from -40°C to +60°C; resists freezing and high-temperature degradation.
• Standard Flange Mounting: Universal DN50/DN80 flange connections for easy installation and retrofitting on most transformer conservators.
