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.
Technical equipment
Advanced Modbus control. Innovative electronic control system
Advanced electronic control system conceived and designed to deliver optimum performance and easier access to information. Thanks to the control via Modbus Master protocol, all key components of the unit are continuously supervised, with over 50 different variables ensuring the real-time monitoring of all operating cycles.
Thanks to the wide full graphic LCD color display, access to all operating parameters is guaranteed in a simple and intuitive way, in addition to icons, progress bars, as well as daily and weekly temperature and humidity charts with specific features dedicated to energy savings and the optimised management of all the unit. Advanced system for recording alarms and hours of operation and predictive safety systems designed to prevent unwanted shut-down failures make the advance Modbus control a reliable tool.
Thanks to the integrated RS485 and RJ45 Modbus or BACnet card, and to the LonWorks and SNMP interface gateway, it is possible to interface quickly and easily to supervision systems and Building Management Systems (BMS).
Large Data Center - G Series
G Series Close Control air conditioners have construction and operating characteristics suitable for meeting the design criteria of the latest generation data centers.
Close control systems in big data centers are designed with redundancy and fault tolerance to minimise the risk of downtime due to equipment failures or maintenance activities. The units have a separate section for fans for mounting under raised floors.
Close control for large data centers is essential for maintaining optimal operating conditions to ensure the reliability, performance, and longevity of the IT infrastructure. They utilise advanced cooling technologies, chilled water or DX cooling, to efficiently remove heat, maintain stable temperatures, and optimal humidity levels throughout the data centers.
