48 V DC air conditioner line for Telecom cabinets, enclosures and compartments.

Dantherm's DC Air Conditioners are slim line true DC air conditioners for energy-efficient cooling in Telecom networks. 

Telecom site uptime during power outage/intermittent power

Dantherm DC Air Conditioners are soft starting and avoid the typical start-up inrush current as seen by AC compressor drives. It is built to run on battery backup thereby ensuring full site uptime and ensuring the site income stream also during power outage.

The safety feature: low voltage disconnect prolongs battery life in case of low voltage from batteries and the Dantherm DC Air Conditioners are therefore highly suitable sites with battery back-up power and hybrid sites powered with renewable energy sources such as solar, wind, fuel cells or hydro.  

Energy efficient

Because our DC Air Conditioners are capacity regulated, they only provide the exact amount of cooling needed. This means that they are much more efficient in use than traditional air conditioners, inverter based DC Air conditioners and even traditional DC Air Conditioners.

In challenging outdoor environments

The DC Air conditioner line is designed for cooling of equipment in challenging outdoor environments and consists of quality components to ensure the long service life demanded by leading telecom companies - knowing that a telecom network is dependent on sites running 24-7-365 under any ambient conditions.

Variable cooling set point

On the DC Air Conditioners 1000 and 3000 you can choose a cooling set point from 20°C up to 40°C, making the units suitable for multiple cooling purposes, whereas the 450 version is designed especially for battery cooling with a set cooling point of 25°C.
