Product Overview
DEFU DC Electric Compressors are specialized components for modern vehicle AC systems, ideal for electric/hybrid vehicles and retrofitted conventional fleets. Operating on direct battery power (12V-380V), they enable engine-off cooling across compact cars, commercial vehicles, and custom applications.
Key Advantages
These units prioritize energy efficiency by eliminating fuel dependency and emissions, while low-noise operation (<74 dB) ensures passenger comfort. Rapid cooling performance adapts seamlessly to extreme temperatures.
Design & Compatibility
Featuring a scroll-type horizontal design, compressors support ±10° mounting flexibility and withstand -10°C to +65°C environments. IP67-rated housings provide dust/moisture resistance, with compatibility for R134a refrigerant and PWM/CAN speed control.
Performance Specifications
Delivering 34 m³/rev displacement and 2000W/3000W cooling capacity at COP ≥3.1, critical specs include 1500-3000rpm speed range, 50A(12V)/90A(24V) max current, and 7.5kg weight. CAN communication enables vehicle system integration.
Customization & Durability
Rigorously tested (500-hour endurance, 30g vibration resistance, 96-hour salt spray), these compressors offer OEM/ODM adaptability with a 6-year design lifespan, complying with GB/T22068-2008 and IEC60335-2-34 standards.
1. Electric & Hybrid Vehicle Integration
Primary climate control in battery-powered EVs and hybrids, utilizing 48V–380V models for engine-independent cooling.
2. Conventional Vehicle Retrofitting:
Upgrade aging AC systems in fuel-powered trucks/buses using 12V/24V compressors without engine modification.
3. Parking Cooling Solutions
Enable "engine-off" cabin cooling in sleeper cabs, ambulances, and fleet vehicles via auxiliary battery power.
4. Specialty Vehicle Adaptation
Custom installations for off-road campers, tractors, and construction machinery .
5. Harsh Environment Operation
Deploy in extreme temperatures (-10°C to +65°C) with IP67-rated dust/moisture resistance.
