Combo cooling

  • Dantherm Combo Cooling 6000/900 - hybrid cooling 6kw Combo Cooling 6000/900

For Telecom shelters and enclosures.

The Dantherm Combo Cooling solution combines free cooling and air conditioning to provide the most energy-efficient cooling and generate huge savings. The solution is designed to save energy in normal running mode and has the advantage of back-up air conditioning in very warm climates.

Total heat management for extreme environments

The Dantherm Combo Cooling units are total heat management systems. They are designed to protect the cabinet, shelter or enclosure from the intrusion of dust and water. This makes the systems perfect for even the most extreme environments and all geographical markets.

High-capacity hybrid cooling

The Dantherm Combo Cooling units mark the beginning of a new generation of hybrid cooling solutions. The units re-think the basics of combo cooling by focusing on high-volume free cooling. The Combos feature a Dantherm-developed air inlet protection feature, the AirMazePat. Pend., which discharges water, sand, leaves and snow before they reach the filter.

  • Dantherm motorized air outlet damper for heat managment in Telecom Sites. The motorized air outlet damper is used in some large sites or sites with difficult air paths. It improves Free Cooling efficiency and temperature distribution in the site.
Free cooling Free cooling Applies outside air to cool. Most energy-efficient cooling method. bullet
Air conditioning Air conditioning Built-in air conditioner ensures that the maximum temperature threshold of the customer is not exceeded. bullet
Heating Heating An external heater can be connected and controlled by the Dantherm CC4 controller. This ensures that the desired temperature is maintained in challenging environments. bullet
Emergency cooling by exceeded max-temperature Exceeded maximum temperature If the internal shelter temperature is above max, the unit assumes a malfunction and initiates maximum free cooling. bullet
Emergency cooling by AC-mains failure AC-mains failure In case of AC mains failure, the unit assumes a malfunction and initates maximum free cooling. bullet
Air mix Temperature regulation In case of cold ambient conditions, full free cooling can be to much. Therefore, the unit regulates the damper air opening gradually in order to maintain the set point temperature. bullet
