Recently, Shandong Wanhuan Energy Equipment Technology Co., Ltd. shipped a batch of custom cold-resistant skid fuel supply units to mining sites in the Russian Far East. The region’s harsh frigid climate demands reliable low-temperature performance, so Wanhuan’s R&D team optimized the skid system with low-temperature steel, upgraded heat tracing & insulation, cold-resistant explosion-proof electric parts and anti-freezing oil circuits to ensure safe startup and refueling at -40°C. The package includes main skid refueling units, generator sets, fire-fighting gear, IoT monitoring terminals and full Russian O&M manuals. Wanhuan handles customs clearance, international logistics and insurance, while technicians offer online guidance for installation and commissioning. This delivery represents a key breakthrough in the Russian market and demonstrates Wanhuan’s capability to develop custom skid solutions for extreme cold environments.
