HIGHLY ETS34 High-Voltage Electric A/C Compressor

The HIGHLY ETS34 High-Voltage Electric A/C Compressor (Model PE34001) is a premium, automotive-grade electric scroll compressor designed to drive the cabin air conditioning and battery thermal management systems in modern Electric Vehicles (EVs). Manufactured by Shanghai Highly Electrical Appliances Co., Ltd. (a major global OEM supplier for automotive HVAC), this powerful compressor features an integrated inverter and operates seamlessly on 400V-class EV architectures.

Key Specifications:

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

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

• Manufacturer: HIGHLY (Shanghai Highly Electrical Appliances Co., Ltd.)

• Model / Part Number: ETS34 (Material #: PE34001)

• Operating Voltage Range: 200V to 470V DC

• Speed Range: Variable from 800 to 8,000 RPM

• Refrigerant Compatibility: R134a / R1234yf

• Compressor Oil: Pre-filled with 150ml of HAF68 POE Oil (Specifically formulated for high-voltage isolation)

• Housing Material: Heavy-duty die-cast aluminum

Key Features:

• Variable Speed Scroll Technology – Delivers highly efficient, vibration-free cooling. The compressor speed can be dynamically adjusted between 800 and 8,000 RPM by the vehicle's thermal management system, providing massive cooling power on demand or dropping to low speeds to save battery range.

• Integrated Inverter (Controller) – The base of the compressor houses a smart, liquid-resistant motor controller. It takes high-voltage DC directly from the battery pack and uses CAN-bus signals to manage the internal 3-phase AC motor.

• Dual Refrigerant Ready – Designed to operate with both traditional R134a and modern, environmentally friendly R1234yf refrigerants.

• Severe-Duty Construction – Built for the harsh under-hood environment. It features robust cast-aluminum mounting ears for vibration-proof installation and heavily sealed electrical connectors to prevent moisture intrusion.

• Factory Sealed & Protected – Ships with sealed suction and discharge ports (currently covered by protective tape in the photos) to ensure no dust or moisture enters the system prior to installation.

Ideal For:

• OEM replacement for compatible 400V-architecture Electric Vehicles (EVs) and Plug-in Hybrids (PHEVs)

• High-performance EV conversions requiring a standalone, high-capacity climate control and battery chilling solution

• Commercial electric trucks and transit bus auxiliary cabin cooling

• Custom thermal management loops in heavy-duty electric construction or mining equipment
