Carel solutions for Data Centers

Data center applications have huge energy consumption. Carel offers high efficiency solutions through optimised and integrated control systems, capable of bringing significant energy savings and consequently reducing the environmental impact of data centers.

Carel solutions range from high tech controllers and inverters to energy saving cooling systems. Carel controllers can manage all kind of compressors, including DC inverter compressors, which are proven to be the most energy-saving technology for data center applications. Concentrated loads with high power density (up to 20 kW per rack) are driving development of new types of units installed near the heat source. These systems have low inertia, because very often their load varies continuously and such variations are usually quite fast: this is why it is important to have a variable speed compressor. The power+ inverter by Carel can be used to control new CRAC units with direct expansion systems that modulate cooling capacity to manage supply air temperature.

Furthermore, this device helps create redundancy. Designing units for 75% load with very high efficiency allows reserve cooling capacity in the event of problems on one of the units. Finally, this inverter can be used to control part freecooling, modulating cooling capacity to make up the remaining capacity required: this is becoming more and more important as new solutions are developed, including integration of Direct and Indirect Evaporative Cooling to create a mix of different cooling solutions for both energy saving and service continuity. This is why communication between controllers is very important, something that Carel guarantees as a result of constant research into specific technologies. Innovation and technological advancement have followed every step in CAREL's evolution. Proof of this lies in milestones such as having been the first company in Europe to design and manufacture a microprocessor-based electronic controller for precision air-conditioners in computer rooms, in the early eighties. 

Carel's experience in this sector has allowed the company to complete projects for data centers in Europe and the US, as partners to the world's most important players in this market.
