IT COOLING
Optimised Climate Solutions for Critical Spaces
Vital Technik specialises in IT Cooling equipment, providing top-tier close control air conditioners for data centres and critical environments.
These units ensure precise temperature and humidity control, high energy efficiency, and are adaptable for diverse applications, embodying cutting-edge cooling technology.
Close control air conditioners
Although optimised for data centres, the technical characteristics of the P series units make them ideal for various types of special applications, including: metrology labs, TV production studios, musical instrument recording and storage rooms, museums and archives, control rooms in power stations and railway junctions.
Moreover, they are ideal for use in many industrial sectors: optics, electronics, electromedical devices, electrical or electronic equipment production, musical instrument production, etc.
GENERAL SPECIFICATIONS
- Versions with upward and downward air delivery.
- Strict control of room temperature and humidity.
- Very high EER (energy efficiency ratio) and low operating costs.
- High usage flexibility and wide range of accessories.
Free Cooling and Two Sources models available
Notes:
(1) Performance refers to: intake air 24°C-45%Rh; R410a refrigerant; condensing temperature 45°C; water temperature 7/12°C; external static pressure 30 Pa. The declared performance does not consider the heat generated by the fans, which must be added to the thermal load of the system.
(2) EER (Energy Efficiency Ratio) = total cooling capacity / input power of compressors + input power of fans (excluding air-cooled condensers).
(3) Sound pressure levels at a distance of 2 m; in a free field; pursuant to UNI EN ISO 3744:2010.
Close control air conditioners for large data centres
In designing air conditioning systems for large data centres, the need to house electrical wires and the enormous quantities of air required to cool the serves has made it necessary to increase the height of the raised floors up to the current 550/1000 millimetres. A large space was therefore created under the air conditioner in which to install the adjustable support. It was then decided to exploit this large space to house the delivery fans without increasing the machine’s footprint, making the most of the available space instead.
GENERAL SPECIFICATIONS
- Separate air-cooling section for mounting under raised floors.
- High delivered cooling capacity to footprint ratio.
- Optimised air distribution in raised floor.
- Reduced energy consumption of fans.
Chilled water versions available in XH (Extended Height)
Free Cooling and Two Sources models available
Notes:
(1) Performance refers to: intake air 32°C-30%Rh; R410a refrigerant; condensing temperature 45°C; water temperature 12/20°C; external static pressure 30 Pa. The declared performance does not consider the heat generated by the fans, which must be added to the thermal load of the system.
(2) EER (Energy Efficiency Ratio) = total cooling capacity / input power of compressors + input power of fans (excluding air-cooled condensers).
(3) Sound pressure levels at a distance of 2 m; in a free field; pursuant to UNI EN ISO 3744:2010.
Close control air conditioners for installation in service corridors
The W Series units feature constructive and operational characteristics able to satisfy the design criteria of latest-generation large Data Centres in the presence of a technical service corridor. The units are designed to withdraw the warm air generated by the servers, coming from the warm corridor, and blow chilled air directly into the Data Hall.
This type of chilled water unit is specifically designed to be modular and customisable, with a range of possible custom configurations to suit the architecture of modern Data Centres. Its reduced footprint and installation in a service corridor means W Series units avoid occupying critical spaces, thus maximising the capacity of the Data Hall.
GENERAL SPECIFICATIONS
- Technical services corridor mounting.
- No space occupied in the data centre.
- Very high EER (energy efficiency ratio) due to optimised airflow.
- Fully customisable to data centre specifications.
Air conditioners for
“in-row” mounting
In air conditioning systems for large data centres, use of the following design concepts has now become a consolidated practice:
- The racks containing the servers are being increasingly positioned in accordance with the hot corridor (or hot aisle), and cold corridor (or cold aisle) layout.
- The air temperatures are left to rise up to 30-35°C in the hot corridor, and 20-25°C in the cold corridor, with very low humidity (never more than 30%).
- The performance of servers is continually increasing, while their size is getting smaller and smaller.
Many more servers can therefore be installed in one rack, allowing the remaining empty racks to be eliminated. At the same time, the dissipated heat rises, and more power is therefore required of the air conditioners.
GENERAL SPECIFICATIONS
- Airflow distribution as close as possible to servers.
- Rear suction from hot aisles and front delivery to cold aisles.
- Front and rear access for ease of maintenance.
- Hydraulic, refrigeration and electrical connections from above or below.

H Series AHU's for Operating Theatres; Radiology Bunkers & MRI's
Thanks to twenty years of experience, TECNAIR presents a new generation of H Series air conditioners dedicated to operating theatres and hospitals, where the primary objective is high air quality.
The H Series units, in their standard configuration, are complete with all adjustment components (heat recovery system, cooling, pre- and post-heating, humidification and dehumidification), sized for the treatment of full fresh air or with partial recirculation. A flexible configuration and a high number of accessories guarantee the use of H Series units for applications such as: operating theatres, laboratories and clean rooms, image diagnosis rooms, wards and intensive care.
