Micro DC Aircon
Compact, Light, Rugged DC Air Conditioning Unit

If your power source is 12V, 24V, or 48VDC as part of a telecom or off-grid solar application, RIGID Micro DC Aircon all-DC air conditioning units are your most efficient cooling choice. The micro dc air conditioning series can substantially reduce power supply/generation costs and battery requirements. An all-DC system means you get the advantage of extremely high efficiency without the need for inverters.

RIGID Micro DC Aircon removes heat from the air which is circulated through the system to cool the heat source and compact space. They are especially applied to critical applications where space and weight are important to them. It is widely used for compact and confined space cooling. DC Air conditioning systems are ideal for cooling bulk heat loads where minimal modification to the system is desired. The mini compressor air conditioner provides an excellent cooling solution where size/space/efficiency are important factors.

If your existing infrastructure requires minimal changes, RIGID Micro DC Aircon is probably your best choice. It is the world's smallest air condition unit, driven by a battery. The micro dc aircon uses the patent mini brushless direct current compression compressor to chill the air within an enclosed environment. The air removes the heat from the payload without the need to adopt a heat exchanger to the existing architecture.

4. How much capacity (horse power) does Micro DC Aircon have?
It has nominal capacity of 450W~550W (1,876Btu) under normal running conditions.
5. What is RIGID Micro DC Aircon included?
The micro dc aircon unit is the ultra-compact and lightest weight, It includes:
1pc x mini compressor
1pc x condenser
1pc x evaporator
1pc x blower
2pcs x fans

It contains refrigerant before shipping, so you just connect to your dc power battery, it works.
6. How many batteries do I need?
10 amps output at least & 100 am/h battery.
7. How long will the micro aircon works connected from battery?
Firstly we need to specify the battery. The 12V aircon nominal 1-8 amps. If we assume about 8 amps continuous. A car battery is usually 35 amp-hours. A prismatic lithium battery from battle born or a 190 amp hour battery from EVE would be a longer run time, just divide the battery by the 8 amps. For example, 100/8=12.5hrs (100 amp hour battery divide by 8).

Technically, it is easy to find 200-300 amp hour batteries and 400-800 or more watts of solar panels, it runs this micro dc air conditioner unit all day.
8. What about the connecting lines?
No need to worry about assembling or pipe connecting, we've done it before shipping, including refrigerant. Engineering Zero!
9. What else do I need to install the micro dc aircon?
You only need to prepare a switch power or connect to battery power, which stores energy and provides enough dc power supply.
10. How much volume or space will DC Aircon Unit cool?
The maximum cooling capacity is 550W (1,876 BTU) unit. Normally it can cool 15-20 square feet (1~2㎡).
11. Does the micro dc aircon need to vent?
The short answer is yes. Like any air conditioning system, RIGID micro aircon unit condenser must be installed outside. Vent the hot air that comes off the heat exchanger to the outdoors.

Portable dc air conditioners pull in warm air, cool it, and expel the cooled air out of the evaporator and the remaining warm air and moisture out of the back of the unit. This warm air and moisture need to be vented out of the room you are currently cooling. Make sure to heat the air exhaust outside. The easiest and most popular way to vent heat air through a nearby window.

Hoses are available as optional parts if you requested.
12. What happens to the moisture in the air or condensate water?
Since the dc air conditioners pull moisture as well as heat out of the air, RIGID small aircon units have self-evaporative technology. This innovative technology internally processes and evaporates the collected moisture and then exhausts it out of the back of the unit.

In climates that are extra humid, some water will be collected in a reservoir located at the bottom of the a/c. So condensate water can be drained by a pipe. In this case, you can either manually empty the reservoir when it is full or use the integrated gravity drain.
13. How noisy is RIGID micro dc aircon unit?
Because of the differences in personal preference, this can be a hard question to answer. Since portable air conditioners contain both a compressor and fan, they sound similar to a window air conditioning unit, which most of us have heard at one time or another. With that said, you want to pay attention to a portable air conditioner decibel rating (dB level) which is located on each product description page.

Most units are between 48 dB (which is the same noise level as falling rain) and 60 dB (which is the same noise level as a normal conversation).
14. Can I become a dealer?
Yes, we work with compressors and HVAC companies in the USA and around the world. Please contact us.
15. What factors should I consider when looking for the micro A/C unit?
BTUs/Room Size — This directly affects the room size and how quickly the unit will be able to cool. The higher the BTU, the larger the area the micro dc aircon can efficiently cool.

Indoor or Outdoor Design — Indoor units expel warm air and moisture and are easy to install. Outdoor units need to be custom-made, which are also fairly easy to install, enclosure or cover is requested while simultaneously pulling in more air to coo
16. What additional parts should I need when install the micro dc air conditioner unit?
DC Power Supply
Temperature Sensor (optional)
17. How can I get better cooling performance?
1. Enough airflow from vents
The hose is shorter is better, so you can get enough airflow from the vents. Plus, you can install an additional blower in-line for the a/c intake if possible. This helps the a/c unit produce a better flow from the outlet vent.

2. Make sure better ventilation
Removing the warm air from the condenser. It is better to install the heat part(compressor/condenser) outdoor for exhausting or add a fan to blow out the hot air for better ventilation.
18. How long is the hose that dc air conditioner comes with?
The lengths of the standard duct are 1 meter (3.28 feet). They are made of PVC plastic. We also accept personalized orders for mass production.
