Railway air conditioning

Standard or custom made Air conditioners for rolling stock.

We assist our customers to achieve the cooling they need. Our low power high output units are compact and can be easily installed on new and legacy trains to enhance passenger and driver comfort. To reduce development cost and lead time we have developed standard products which can be adapted to fit your application. Custom made units are possible as well, but with a minimum of 50 units.

 
Why DC Airco units make sense for railway applications:

• Low power consumption 2-3 lower than a normal AC
• No power surge during start-up
• In house climate chamber testing
• Factory tested
• Easy installation -no on site refrigerant charging needed
• Long service intervals
• 2 year warranty – all parts are long life
• PLC package with  self diagnostics

Dc Airco units are designed to meet the following specifications:

• Fire & smoke specification: BS 6853 ; DIN 5510 ;  NF F 16-101; EN 45545
• Vibration and shock: EN 61373:2010
• EMC: EN 50121-3-2:2006; EN 55011:2007/A2; EN 61000-4-2/6
• Standard for passenger cooling: EN 14750
• Standard for driver cab cooling: EN 14813

Telecom air conditioning

DC Airco telecom products are availably in 24 and 48 vdc.

The first product in this series was developed to work if there is a power black out. 
Now days there are sites where the customer removes the normal grid air conditioners and replace them with DC12500 because of its total energy consumption and its ability to work from the battery bank.

In other cases the site is turn in to a solar/wind energy drive site or to save fuel and reduce running hours of the generators the 230/115 volt driven Air conditioners are replaced by the DC12500.

But if the customer can't make a big opening in the side wall of the shelter the DC9200 and DC17000 are recommended.The evaporatorcan be mounted on side or roof of the shelter.

Military air conditioning

Standard or custom made Air conditioners for Military

DC Airco is supplying standard and custom made products to defence companies in
the EU and USA to cool equipment and / or people. 
Several defence contractors have selected DC Airco as their supplier for cooling solar/diesel powered equipment shelters (DC 12500HA 24-48 VDC) and radar trucks (DC 9200HA 24-48 VDC) in remote areas.

For unmanned border patrol the DC12500 telecom unit is mainly used in 24 or 48 VDC in desert areas.

For vehicles also the DC9200 split unit is used (same unit as in mining refuge shelters)
The DC 9200 split unit is developed in 2007 to cool fuel cell powered  telecom sites and is later used for railway projects, mining and defence. A larger version of the DC 9200 is called DC 17000.


 

Mining air conditioning

DC Airco mining products are availably in 24 Vdc

Our specially designed  mining units are built to cool underground refuge chambers on a 24 VDC battery pack. Powered by sufficient batteries these air conditioners offer up to 4 days of cooling to miners trapped after a disaster.

Due to the many unfortunate underground mining accidents over the last years that have become news all over the world, in combination with improved raw material prices many mining companies are willing to invest in the wellbeing of their employees.

In many mines the temperature is between 28 C and 33 C with a high humidity. If the trapped miners are sitting in a closed refuge chamber /steel container the temperature and humidity rise to unacceptable high levels. Therefore many refuge chambers are equipped with air conditioning units to lower the indoor temperature and remove the excess humidity.

DC Airco developed special 24 volt air conditioners for this application. 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! 

Trucks airconditioning

DC Airco truck products are availably in 12 & 24 Vdc

Unique technology

The DC Airco 37 cc rotary compressor is extremely efficient and powerful.
The Air Conditioner is specially designed to work with the compressor.
All DC Airco units have a soft start. No excessive startup currents.
This unique technology has been developed and tested in Europe.
DC Airco units are prefilled with R134a coolant which meets all ozone protection requirements.

Easy of Installation

It’s easy to install. Any qualified mechanic can install a DC Airco.
DC Airco Rooftops are fully self contained - just connect the wires to a full battery and they start cooling!
