Low consumption with a high cooling output

The very efficient DC powered direct current air conditioner combines a very low consumption with a high cooling output and is fully dc powered. The cooling duty of this fully DC powered unit is 2-3 higher than a normal 230 VAC and 6 times higher than a motor driven AC using with the same cooling and there is no power surge during start up.

DC Airco has developed these special 24 volt DC powered direct current air conditioners for underground mining refugee shelters. These units have been tried and testing in real conditions having 30 man in a chamber with outside temperature and humidity similar to a mine. It has 2-3 more efficiency than a normal AC on a inverter and a higher water condensing rate keeping the humidity in the shelter acceptable. Compared to CO2 cooling you need a much smaller space because the energy density of a battery is much higher than CO2 bottles. 1 battery pack with the size of a box pallet can replace 100+ CO2 bottles!  


The DC 7200B equipped with the Premium controller

The Programmable Premium controller provides our customers a solution that is fully integrable in there system, with full control over the DC Air conditioning of many applications. Every product can be customize without unnecessary cost and complexity to operations because the free programmble controller.

Description of the premium controller

The high quality microprocessor controller makes the DCAirco products more efficient in energy consumption. The controller will provide unlimited features to meet our customer requirements, making it easier to reduce development-installation time and in gerneral there is no need for additional equipment.

User interface

The display is showing the set point and ventilator speed, in one view all you need to know and easily to adjust. Creating the perfect climate for all users.

Diagnostics of the DCAirco product

Other great features of the controller are the standard alarm outputs and readings through Modbus or voltage free contacts. With these functions the costumer will be able to react quicker on possible issue’s or upcoming maintenance. As example: if a ventilator is blocked or damaged from the outside the controller will give an notification through these alarm outputs saving traveling en maintenance time.


The kit contains the following parts: Indoor unit, outdoor unit, prefilled hoses and controller box fully operational when you unpack it. Just connect to the batteries, set the controller to the desired temperature.



Indoor and ourt door units are made of zinc plated sheet steel 1,5 mm with grey RAL 7035 powder coating. All closing material are stainless steel. The unit is easy to be installed outdoor on existing appliances. 


Testing data
Cooling duty varies on climatic conditions and altitude- consult factory for specific applications. Cooling duty measured with 50 %RH indoor and 85% outdoor. 

Instruction video: Opening-closing of the self sealing quick connectors.

DCAirco's self sealing quick connectors specially designed for the pre-filled hoses between the in and outdoor units of the heavy duty split air conditioners. Opening and closing can easily be done (multiple times) by hand, wearing gloves and glasses for safety reasons.
