best 12v air conditioner compressor

Guchen Fully Electric DC 12V Air Conditioner Compressor 

It is a versatile auto air conditioning compressor available in 12V, 24V, and 72V, and has additional versions available with 1) PWM speed adjustment, 2) 0-5V speed adjustment, 3) 0-11V speed adjustment and 4) Three-speed adjustment. The DC 12 volt compressor can be operated with digital display panel (if you choose PWM speed control version) or a rotary switch (if you choose the left 3 versions).
The innovative 12v mini ac compressor is best selling for no-idle solutions. It is a good fit with the vehicle’s engine-off power needs. For any no idle application, such as 12v semi truck hvac system, 12v van air conditioner, it is a great alternative.


Benefits of Guchen DC 12V A/C Compressor

■ Wide application
For industry use on vehicles and machines: trucking industry (parking trucks/semi-trucks/lorries), caravans, automotive, construction machinery, heavy vehicles, farming equipment etc. With cooling capacity up to 2.4kw, the 12V A/C compressor is capable of providing high performance no-idle air conditioning for both individuals and fleets.
■ Easy to wire in
The 12V compressor is with 3 wiring looms (wire size: 1.1m) in total; the red wire for positive terminal, the black one for negative terminal, the middle black one for control (the compressor speed). it is very simple to wire in.

■ Built tough and powerful
They are durable and strong, which means minimal maintenance required. 
They are compact. You can put it anywhere convenient. 
The advantage of Guchen DC 12 volt A/C compressors is with heavy duty cast aluminum structure, which can be mounted in outside application. The hermetic reasonable design provide durability for the most extreme working conditions.
■ Brushless motor
The 12v air conditioner compressor’s brushless motor increases the overall system efficiency. It is with high reliability (no brushes to wear out). The compressor speed and efficiency are also greatly improved, therefore brushless motor is the most suitable motor used in variable-speed automotive electric compressors.

■ Scroll Technology
Scroll technology for electric air conditioning compressors has seen successful advances during the past few years of research, development and application. 12 volt DC scroll type compressor designed by Guchen Industry is with demonstrated superior value in auto ac systems, heat pump systems and transportation refrigeration systems that require scroll designs.
■ Inverter built in
An inverter is used to regulate precisely the speed of electric motor to continuously adjust the temperature. It is the most energy efficient technology, and has been the new trend in automotive HVAC industry. 
12V Air conditioner with variable speed compressor (inverter built in) operates more quietly, reduces energy consumption and provides better value in the long run.
With inverter built in, the electric air conditioning compressor provides maximum cooling when it’s needed, yet reduce electric load when it’s not. Guchen 12 volt variable speed compressor is a preferred choice for those who are struggling to properly maintain temperature , and looking for cost-effective A/C solutions.
