"Anti-Freezing Genes" of HUAQUAN Power Plateau-Specific Diesel Generator Sets

In extreme cold environments like the Antarctic ice sheet and Siberian oil fields, HUAQUAN Power diesel generator sets can start with a single click even at -50°C. Let’s take a look at the black technologies hidden within them

Material Revolution

The crankshaft and cylinder block are made of nickel-based alloy steel, which maintains toughness even at -60°C and can avoid cold brittle fractures.

Silicone seals: Custom fluorosilicone rubber (FVMQ) seals do not harden at -55°C, whereas traditional nitrile rubber cracks at -30°C.

Three "Heating Wonders" in the Starting System

Cylinder preheating system: A patented electric heater plug combined with a circulating oil circuit design can raise the oil temperature from -50°C to -10°C within 15 minutes.

Battery insulation compartment: The lithium-ion starting battery is equipped with a built-in carbon fiber heating film, maintaining a capacity retention rate of over 90% in -40°C environments.

Fuel preprocessor: Multi-stage filtration and electric heating devices prevent diesel from waxing (No. -35 diesel can still atomize at -45°C).

Polar-Exclusive Operation and Maintenance Plans

Lubricating oil selection: 0W-30 fully synthetic oil is mandatory, with a pour point as low as -57°C.

Cold start operation specifications: Direct ignition can damage piston rings. The correct starting procedure is: preheat, idle for 3 minutes, and finally load gradually.

Power guarantee in extremely cold environments is both a technological contest and a survival test. In 2025, as domestic polar diesel generator sets broke the -60°C limit, even Russia's Norilsk Nickel purchased them in batches—a fact that perhaps speaks louder than any data.
