1 CLIMATE. CUSTOMIZED. CyberHandler2 from 30KW to 520 KW The indirect evaporative free-cooling Air Handling Unit

2 Flexible & Efficient 11 sizes from 30 kw up to 520 kw to fit your needs with maximum efficiency Typical ppue between 1.02&1.10 The CyberHandler2 offers you a wide range of capacities, from 30 kw to 520 kw, in 11 different sizes allowing you to find the best compromise cost/efficiency according to your specific requirements. Each size will be an optimized and customized solution that perfectly fit to your installation requirements with the maximum efficiency and flexibility. With an high efficient indirect evaporative free-cooling design and using the industry state-of-the-art components the CyberHandler2 minimizes the running costs and achieve ppue s down to 1,02. The unique STULZ C7000 controller specially designed for precision control of mission-critical environments, with a proven track record of success within this industry, makes this product the most energy efficient trusted option in the market. Operation Modes & Benefits operation modes based on ambient air temperatures: 0 / Dry Mode Top - Up Mode Wet Mode Dry Mode (free-cooling only): Adiabatics OFF Mechanical Cooling OFF Wet Mode (Adiabatic): Adiabatics ON Mechanical Cooling OFF Top-Up Mode (Mix Mode): Adiabatics ON Mechanical Cooling ON The benefits of the indirect evaporative cooling: Outdoor contamination free Evaporative cooling extends indirect free-cooling operation all year round Unbeatable energy efficiency levels with ppues in the range of Lower total cost of ownership (TCO): reduced CAPEX, OPEX, maintenance, infrastructure costs, etc Internal white space is reduced to a minimum, as the unit is installed externally Simplified installation: easier management of power cabling, pipes and water, not needed inside the white space Downsizing of the electrical infrastructure allows savings in CAPEX of 6-8% Faster return of investment

3 Installation Configurations 2 configurations available to adapt to your installation requirements Wall Configuration SH/RH * In this configuration the horizontal path of the IT room supply and return air allow the units to be installed directly in the wall of the building in a perimeter distribution. * SH: Supply Horizontal RH: Return Horizontal Roof Configuration SB/RB * This configuration allows the supply and return air to enter directly into the IT Room ceiling. No ductwork is needed on the roof. * SB: Supply Bottom RB: Return Bottom

4 Cooling Configurations Indirect evaporative free-cooling The ideal solution when the outdoor ambient conditions are suitable to reach the room supply temperature set point without the need of additional mechanical cooling. Only the adiabatic free-cooling system is enough to achieve the required cooling capacity. Indirect evaporative free-cooling with Top-Up integrated DX cooling system An integrated DX Top-Up cooling system helps the Air Handling Unit to achieve the required cooling capacity when the extreme outdoor ambient conditions are reached. The complete DX system (evaporator/ compressor/condenser) is inside the unit. The top-up DX system can reach up to 30% of the total required cooling capacity.

5 Indirect evaporative free-cooling with CW Coil Top-Up/Redundant cooling In case of extreme outdoor ambient conditions, the adiabatic cooling system is complemented by an integrated chilled water coil connected to a remote chiller. Options for the full CW coil redundancy or top-up are available. Indirect evaporative free-cooling with redundant DX cool. system In this configuration the Air Handling Unit is equipped with a DX coil (evaporator and compressors) which connects to an outdoor condensing unit allowing the system to reach 100% redundancy only with the DX system.
