Guchen GC34A350 High-Voltage Electric A/C Compressor

The Guchen GC34A350 High-Voltage Electric A/C Compressor is a heavy-duty, automotive-grade electric scroll compressor designed to drive the cabin air conditioning and battery thermal management systems in Electric Vehicles (EVs) and commercial electric equipment. Manufactured by Zhengzhou Guchen Industry Co., Ltd., this unit features an integrated top-mounted inverter and is optimized for 350V DC architectures, providing highly efficient and reliable cooling.

Key Specifications:

• Category: Automotive Parts & Accessories / Engine Cooling & Climate Control / A/C Compressors

• Product Type: High-Voltage Electric Scroll A/C Compressor

• Manufacturer: Zhengzhou Guchen Industry Co., Ltd.

• Model / Part Number: GC34A350

• Displacement: 34 cm³/rev (34cc)

• Rated Voltage: 350V DC

• Speed Range: Variable from 1,000 to 6,000 RPM

• Refrigerant Compatibility: R134a

• Compressor Oil: Pre-filled with 120ml of RL68H POE Oil (Formulated for high-voltage dielectric isolation)

• Control / Communication: CAN Bus (Baud Rate: 500 kbps)

• Electrical Connections: 2-Pin Circular High-Voltage DC receptacle (Amphenol style) and a 6-Pin Low-Voltage/CAN-bus receptacle

• Housing Material: Heavy-duty die-cast aluminum

Key Features:

• Integrated Inverter (Controller) – The square upper housing contains a smart, liquid-resistant motor controller. It takes high-voltage DC directly from the battery pack and uses 500kbps CAN-bus signals to precisely manage the internal 3-phase AC motor.

• Variable Speed Scroll Technology – Delivers highly efficient cooling on demand. The compressor speed can be dynamically adjusted between 1,000 and 6,000 RPM by the vehicle's thermal management system, providing massive cooling power when needed or dropping to low speeds to conserve battery range.

• Severe-Duty Construction – Built for harsh commercial environments. It features thick cast-aluminum mounting points, a heavy-duty steel base bracket, and heavily sealed electrical connections to prevent moisture and dust intrusion.

• Factory Sealed – Ships with sealed suction and discharge ports (currently covered by protective material in the photos) to ensure no moisture or contaminants enter the system prior to installation.

Ideal For:

• High-performance EV conversions and custom Hot Rod builds requiring a standalone, high-capacity climate control solution

• Commercial electric trucks, delivery vans, and transit bus auxiliary cabin cooling

• Custom thermal management loops for chilling high-voltage battery packs in EVs

• Heavy-duty electric construction, agricultural, or mining equipment HVAC systems
