It efficiently controls moisture ingress into the transformer conservator, maintains insulation oil quality, prevents oil emulsification and insulation degradation, and supports long-term stable operation of high-voltage power equipment.

Key Features

• Vertical Tower Structure: Slim, tall cylindrical design maximizes silica gel capacity in limited installation space.
• Large Desiccant Volume: Holds 5kg–20kg of indicator silica gel (orange/blue), greatly extending replacement intervals.
• Dual/Oil-Seal Protection: Multi-stage oil cup and labyrinth seal to prevent oil splashing, dust entry and moisture backflow.
• High-Strength Housing: Made of thickened carbon steel, stainless steel or cast aluminum with anti-corrosion coating for outdoor durability.
• Stable Airflow: Uniform air distribution through the desiccant bed for consistent, efficient dehumidification.
• Easy Maintenance: Top-loading port for silica gel refilling; detachable oil cup for quick cleaning and inspection.
• Weather & Corrosion Resistance: IP55–IP65 protection, suitable for high humidity, coastal, industrial and remote areas.
• Standard Flange Connection: DN50/DN80/DN100 flanges for easy installation and retrofitting.
• Wide Temperature Range: Operates stably from -40°C to +60°C without performance degradation.
