All details about CyberHandler 2
The complete solution
CyberHandler 2 is more than a product. We have a full range of services and features available regarding the evaporative cooler to offer you a turnkey solution for the data center cooling.
- For small to large data centers
- Indirect Free Cooling
- Adiabatic evaporative cooling
- IT sector
- Flexible adaption to every project
Technology and Infrastructure
- Indirect Free Cooling: No contamination from outside air
- Unbeatable efficiency levels with pPUE values up to 1.02 depending on application and location
- Year-round operation with adiabatic cooling via evaporation
- Outdoor installation – Saves space in the data center
Operating Modes
The special construction with its extremely efficient combination of Free Cooling and adiabatic evaporative cooling reduces energy costs. The system has been optimized to such an extent that in most regions, 100 % mechanical cooling is no longer necessary. pPUE values as low as 1.02 can be achieved.
CyberHandler 2 Select
The high-performance CyberHandler 2 Select software makes choosing every air handling unit as easy and agreeable as possible. Its user-friendly interface helps you to optimize and customize the unit to suit your project requirements.
- Calculation of the annual energy and water costs
- Simulation of individual product requirements in the CyberHandler 2 Select and optimization of operating conditions
Installation Configurations
Our high-performance air handling units are positioned directly on or next to the building. All the necessary chilling components are integrated in the units' housing, saving floor space in the data center and facilitating maintenance, as the service engineers no longer need to enter the data center.
Wall mounting
- Supply air and exhaust air are routed through the air handling unit horizontally
- The supply air duct can be either connected to an existing raised floor or routed directly into the data center
- The return air is fed out of the data center directly into the CyberHandler 2
- This type of installation is particularly suitable for data centers where space is not restricted.
Roof mounting
- The air is conducted through the ceiling of the rooms into the CyberHandler 2
- No additional air ducts are needed outdoors for connection
- Fewer points of contact with the environment
- Noise emissions are reduced
- Unauthorized access is prevented
Control and monitoring
- Designed specifically for precision control of mission-critical environments
- Energy-efficient control concepts onboard (CW standby management, raised-floor pressure management, Indirect Dynamic Free Cooling)
- Preservation of parameters during firmware updates
- Onboard protocol Modbus RTU (customizing Modbus data point list)
- Freely configurable digital alarm inputs
- Integrated data logger
- Internal Modbus component communication bus
- Hardware periphery check after boot sequence
- The following BMS protocols are supported: BACnet IP, BACnet MS/TP, Modbus TCP, LonWorks, http and SNMP
WIB 8000
The WIB 8000 all-in-one-web interface is user-friendly and highly functional, and it offers easy data exchange and monitoring with global adaptability.
Functions and Monitoring:
- Alert information via email to up to five recipients
- Ongoing retrieval of data from the controller
- Monitoring of up to 32 units via Web browser
- Ethernet port
- Bus-independent zone operation
- Easy connection to existing building management system
- Works via HTTP and SNMP in parallel
- No JavaScript, no cookies

Service
- Simplified installation:
Problem-free routing of power cables, water pipes and other piping outside the data center - Optimized maintenance conditions
- Service engineers do not have to enter server rooms
- Fast, low-cost maintenance - Low total cost of ownership (TCO)
- Simplified capital expenditure (CAPEX), operating expenditure (OPEX), and repair and infrastructure costs
- Reduced electrical infrastructure enables CAPEX savings of 6-8 %
Climate. Customized.
From standard units to fully customized solutions
The ability to offer such a wide range to customers is the embodiment of our philosophy, "Climate. Customized.". Size, design, air conduction, system or control: STULZ’s CyberHandler 2 can be precisely adapted to your individual requirements.
