Efficiency and performance


High performance and lower power consumption with EC fans and DC compressors with inverter regulation, which modulates the cooling capacity to match the application requirements.

A reduction of annual energy consumption and an increase of the energy efficiency ratio compared to a fixed speed compressor can be achieved thanks to the optimisation of the working conditions and efficiency of the brushless DC motor.

An EEV (electronic expansion valve) maximises the performance of DX cooling circuits, especially under part load conditions.


Cooling circuit advanced management system


All DX units are equipped with an innovative cooling circuit control system, which allows simplified management, easier maintenance, and optimised operational safety. 

The Smart Cool system allows the operating conditions to be monitored throughout the entire cooling cycle.

Evaporation and condensing pressures, suction and discharge temperatures are just some of the parameters measured by this management system.


SMART net


The SMART net local area network (LAN) makes it possible to actively share the workload among all the units in the group. Thanks to the distribution of workload, system efficiency can be increased by optimising the operation of the main components such as fans, compressors, electric batteries and humidifiers. 

With the Multimaster system, each unit is able to take control of the local network even if communication among units is defective (broken or damaged cable), or in the case of shutdown of one of the units.

In-Row solution - R Series


The introduction of high density servers requires the installation of small footprint close control units positioned between the racks. The R Series are the perfect solution for this type of data center, supplying cool air directly in front of the racks.
