Direct Current Air Conditioning Units

RIGID direct current (DC) air conditioning units use DC compressors instead of traditional AC compressors. The electric 12V, 24V or 48V A/C are designed to be portable and can be easily moved from one room to another, making them convenient options for those who need mobile air conditioners in different areas outdoors or indoors.

RIGID portable air conditioning units typically run on batteries, solar power, or DC power sources, making them ideal for use in areas where there is no access to AC power or even off-the-grid. The DC mobile A/C units are also commonly used in off-grid locations such as cabins, RVs, and boats. Using mini DC compressors which are smaller and more efficient than traditional AC compressors, makes RIGID air conditioner an ideal choice for use in portable and battery air conditioning applications. They are also more energy-efficient and have a lower environmental impact than traditional AC compressors.

DC Air Conditionings use vapor compression technologies. By removing the heat from the room, the air circulates chilled air without changing the existing architecture of the system for the user. It is typically a small A/C for controlling the humidity, ventilation, and temperature in a confined space or vehicle, typically to maintain a cool atmosphere in heat conditions. It consists of a mini compressor (12V/24V/48V), a drive board,  a condenser, an evaporator, a blower, a filter drier, and refrigerants fully charged.

RIGID DC Air Conditioning units satisfy the growing market that wishes for tiny cooling equipment. Apart from standard products, we also provide custom and design services to meet customers’ specific needs.

  • “Are you looking for a cooling system for Conversion Camper Van’s and other DIY projects? AC units in today’s market are to big and require big amount of electricity to be run for few hours only. Good thing that we came across this Micro AC unit “DV1910E- AC” 12V , Pro from RIGID! Best thing ever. Well build, easy to install & runs in our solar system! Best cycle cooling system period”

    - CTO Yaneli Callado
  • “This is a very nice, well made unit. It seems to work better than the AC on my big motor on my truck. My only advice is to make sure that you have a 24v system, or be prepared to purchase a DC to DC boost regulator convertor, (still worth it if you need one). Also be sure that your generator, or APU unit for maintaining your batteries is sufficient for the power requirements of the AC unit. Even though I ran into these issues, I am very pleased with this unit. Nice and cold.”


    - Director Roger Olson Jr
  • “Good product – decent noise levels and impressive cooling for a 12v system. “
