The Electrocooler 'half system' allows existing AC cars to use our electric compressor and modern condenser with the existing evaporator blower mounted in the smuggler's box.
Fits Porsche 911 models 1965 to 1989 with factory/dealer fitted AC.
If your factory or dealer fitted evaporator / blower is in good condition but your compressor and hoses are tired, this is the kit for you. The kit contains compressor and mounts for fitment ahead of the fuel tank. The new condenser can be fitted in place of the washer bottle on 74 onwards cars. Early cars can mount the condenser in the rear wheel well. Complete new set of hoses and all wiring are included.
This is a 'half system' AC system to be used with the factory evaporator/blower.
- All Electric. All modern components

Porsche Air Conditioning Compressors | Reliable Cooling Power & System Performance
The air conditioning compressor is the heart of your Porsche’s A/C system, responsible for circulating refrigerant and maintaining pressure to deliver cold air efficiently. It compresses the refrigerant gas and sends it through the condenser, ensuring consistent cooling performance and comfort in all driving conditions.
At Design911, we supply high-quality air conditioning compressors engineered to match or exceed original standards. Manufactured from premium materials with precision-balanced internals, our compressors provide smooth, quiet operation and long-term reliability.
Whether you’re replacing a failed unit or restoring your Porsche’s climate system, our compressors ensure efficient cooling, consistent pressure regulation, and dependable operation for years to come.
What Does an Air Conditioning Compressor Do?
The compressor is a key component that maintains the flow of refrigerant through your Porsche’s A/C system.
Core Functions:
- Compresses and circulates refrigerant gas through the condenser and evaporator.
- Maintains correct pressure levels for efficient cooling.
- Ensures steady refrigerant flow for consistent cabin temperature.
- Supports climate control functions and defrost systems.
- Provides smooth, quiet operation under all driving conditions.
Without a functioning compressor, the air conditioning system cannot cool effectively, leading to warm air output and reduced performance.
Why Do Air Conditioning Compressors Fail or Wear Out?
Over time, compressors are subject to extreme pressure, heat, and mechanical wear, which can lead to internal or external failures.
Common Causes of Failure Include:
- Loss of lubrication due to refrigerant leaks.
- Contamination or moisture in the A/C system.
- Seized bearings or worn clutch assemblies.
- Electrical faults in the compressor clutch or relay.
- Excessive pressure from blocked condensers or expansion valves.
When a compressor fails, symptoms may include warm air from vents, unusual noises, oil or refrigerant leaks, or the A/C system failing to engage.
Why Replace Your Porsche Air Conditioning Compressor?
Replacing a worn or faulty compressor restores proper cooling efficiency, prevents further system damage, and ensures reliable temperature control.
Key Benefits:
- Restores efficient and consistent air conditioning performance.
- Prevents system contamination and costly compressor failure.
- Reduces noise, vibration, and harshness (NVH).
- Improves refrigerant circulation and cooling response.
- Compatible with Porsche 911, Cayman, Boxster, Panamera, Macan, and Cayenne models.
- Ideal for A/C rebuilds, maintenance, or climate control restorations.
When replacing the compressor, it’s recommended to also replace the receiver-drier and flush the system to remove contaminants for optimal performance.
