RIGID Micro DC Aircon - Built for Smallest Space Cooling.

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.
