• Dantherm DC Split Air Conditioner 3500 for Telecom and battery compartment cooling DC Split Air Conditioner 3500

48V DC Split Air Conditioner for Telecom cabinets, enclosures and battery compartments.

The Dantherm DC Split Air Conditioner is a high-efficiency, purely DC-powered split air conditioner for Telecom networks. The solution eliminates the need for an inverter and has capabilities far beyond those of conventional comfort cooling systems.

Site uptime in weak power networks

The DC Split Air Conditioner is designed for energy-efficient cooling of Telecom sites dependent on running non-stop under any ambient conditions. The unit is built to run on battery backup and thus ensures site uptime, even during power outage and intermittent power.

Efficient cooling for hybrid sites

The unit runs purely on DC power and a low voltage disconnect feature prolongs battery life in case of low voltage from batteries. The Dantherm DC Split Air Conditioners are therefore highly suitable for sites with battery backup power and hybrid sites powered by renewable energy sources.  

Energy-efficient DC cooling

Because the Dantherm 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 without inverters.

Cooling On Demand Controller setting Normally, a DC split air conditioner is set to run alone with an individual cooling set point. When set for Cooling On Demand, the split air conditioner is controlled by another cooling unit/control system, known as a master. The split unit only runs, when activated by the master. When activated, the split unit measures the actual internal temperature and adjusts cooling accordingly to reach the desired set point. bullet
