Key Features:

1. Runs on 12V DC Power:

   • Designed to operate directly from a 12V battery system, making it ideal for cars, trucks, boats, and off-grid setups.
     

2. Inverter Technology:

   • A variable speed drive adjusts the compressor's speed based on cooling demand.
   • More efficient than traditional fixed-speed compressors, leading to better energy savings.

3. Compact and Lightweight:

   • Smaller and lighter than traditional belt-driven compressors, making them easier to install in tight spaces.

4. No Belt or Engine Dependency:

   • Unlike traditional vehicle AC compressors that rely on the engine’s serpentine belt, a 12V inverted compressor operates independently, allowing air conditioning to function even when the engine is off.

5. Energy Efficient & Lower Power Consumption:

   • Variable speed operation allows the compressor to adjust its power
   • consumption, optimizing performance and battery life.

 

A 12V Universal Air Conditioning Evaporator with Cooling and Heating is designed for custom or retrofit HVAC installations in vehicles such as classic cars, trucks, RVs, and off-road vehicles. This unit typically operates as part of a 12V electric air conditioning system, with heating functionality requiring connection to the vehicle’s coolant system.

Key Features:

✅ Cooling Function:

• Uses a 12V electric compressor To circulate refrigerant and cool the air.
• Works with R134a refrigerant, making it compatible with most aftermarket AC systems.
• Equipped with multiple fan speeds for adjustable airflow.

✅ Heating Function:

• The heating system operates using the vehicle’s engine coolant.
• Requires hot coolant lines to be connected to the evaporator’s heater core.
• A water valve (manual or electronic) controls the flow of hot coolant to regulate temperature.
• Provides efficient heating without additional electrical load, utilizing the vehicle’s engine heat.

✅ Universal Fitment:

• Compact design suitable for dash or under-dash mounting.
• Works in cars, trucks, tractors, campers, and custom builds.

✅ 12V Operation:

• Compatible with 12V vehicle electrical systems, making it easy to integrate.
• Some models offer remote control or manual switches for temperature adjustment.

Installation Considerations:

• Cooling: Requires connection to an external 12V electric compressor and condenser unit.
• Heating: Needs two coolant hoses (inlet and outlet) plumbed into the vehicle’s heater core circuit.
• Mounting: Can be installed inside the dashboard or as an under-dash unit.
• Power: Runs on 12V power with a fuse-protected circuit.

This type of unit is ideal for off-road builds, classic restorations, and vehicles without factory air conditioning, providing a reliable climate control solution with both cooling and heating capabilities.

 

 

 

 

 

 

 

 

 

 Scroll Type DC 12V 24V Electric Air Compressor

 

A 12V Variable Speed Scroll Compressor is the latest technology in vehicle air conditioning, offering higher efficiency, quieter operation, and better cooling performance compared to traditional piston compressors. These compressors are ideal for electric and hybrid vehicles, off-grid campers, and custom AC retrofits.

Key Features of a 12V Variable Speed Scroll Compressor:

✅ Variable Speed Control:

• Adjusts speed based on cooling demand, reducing power consumption and improving efficiency.
• Uses an inverter-driven brushless DC motor (BLDC) for smooth operation.
• Speed range: Typically from 1,500 to 6,000 RPM, allowing optimized cooling output.

✅ Scroll Compressor Design:

• Uses two spiral scrolls instead of pistons, resulting in lower noise, reduced vibration, and longer lifespan.
• More energy-efficient compared to traditional piston compressors.
• Provides consistent cooling even under high-load conditions.

✅ 12V Operation – Low Power Draw:

• Designed for vehicles, campers, boats, and off-grid applications.
• Consumes less power compared to traditional AC compressors, making it ideal for battery-powered systems.
• Can run on solar-powered or auxiliary lithium battery setups for off-grid use.

✅ Works with R134a & R1234yf Refrigerants:

• Compatible with standard automotive AC refrigerants, making integration easier.
• Some models support newer eco-friendly refrigerants for reduced environmental impact.

 

12V Variable Speed Scroll Compressor – Amp Draw & Specs

A 12V variable-speed scroll compressor is designed for efficient cooling while consuming less power. The amp draw depends on the operating speed, cooling demand, and system configuration.

Typical Amp Draw Based on Speed:

Speed (RPM)	Power Consumption (Watts)	Amp Draw (at 12V)
1,500 RPM (Low)	~100W	8-9A
3,000 RPM (Medium)	~200W	16-18A
6,000 RPM (High)	~400W	32-35A

🔹 Idle/Standby Draw: Some units consume 1-2A in standby mode when not actively cooling.
🔹 Startup Surge: The initial startup can momentarily draw 40-50A before stabilizing.
🔹 Battery Considerations: Best used with a high-capacity deep cycle battery (AGM/Lithium) for reliable operation.
