Conteg Air-cooled chiller

Get the complex cooling system from one experienced supplier.

We are pleased to announce that we are extending our current cooling portfolio with air-cooled water chillers Conteg. The biggest and most important part of any cooling system. These devices produce cold water and supply it to the indoor cooling units. CoolTeg and CoolTop indoor cooling units take heat from the data center room and transfer it into cold water. The chiller can transmit the heat into the external environment. Each chiller (sources of cold) includes a complete refrigerant circuit, compressor, air-cooled condenser, expansion valve, and evaporator. A control system is naturally part of the unit as well. The range of cooling capacity is from 5.5 kW to 1400 kW. We offer four basic series of Conteg chillers. A wide range of optional accessories is available, including a free-cooling function, which allows each customer to choose a suitable chiller for their datacenter requirements. With this step, we are able to provide you a complete cooling solution for your data center.
