Air handling unit for data center cooling
The STULZ CyberHandler is a centralized precision cooling solution that is specially designed to free up space in the data center, allowing more room for IT equipment. The CyberHandler can be mounted on the roof or the exterior wall of the building.
Features
Modular design
Direct & Indirect free cooling available
Coil bypass for reducing the loss of air pressure under a low heat load
Flexible connections for return air, supply air and outside air ducts
Powder-coated aluminum panels – ensure air tightness, protect against reflected sunlight and temperature losses
Aluminum housing for corrosion protection and a low weight
Maximum energy efficiency for high circulating air and supply air temperatures (in accordance with ASHRAE 90.1)
STULZ E² controls – data center specific with user adjustable set-point envelope
STULZ offers the broadest range of cooling capacities for chilled water (CW) and direct expansion (DX) units on the market. With 20-1,080 kW of cooling, there is an air conditioner (CRAC) or air handler (CRAH) for every mission critical application.
CRAH - Chilled Water (CW)
Largest capacity perimeter CW air handlers in the industry
Greater airflow than other solutions
Multiple EC Fan options (additional fans in same size cabinet)
All EC Fans mounted in the cabinet meet full performance without having to be dropped into the raised floor
Fewer units at higher capacity can significantly reduce capital cost and operating cost
2 x CW valves standard on CFD-510 and larger units (option for 1 CW valve)
Dehumidification efficiently achieved through reduced air volume at maximum cooling
Standard and seismic floor stands available for all CW units
Filter plenums designed with increased surface area for filtration, lower pressure drop, and improved energy savings
Standard MERV 8 filters (optional up to MERV 14 filters)
100% front access on all sizes
Made in the USA
CRAC - Direct Expansion (DX)
DX systems provided with highly efficient and reliable low noise scroll compressors
Single or multi-stage compressor arrangement including tandem configurations
Micro plate heat exchangers offer major improvements in heat transfer
Optimized AWS/Free-cooling coils to closely match DX cooling capacities, increasing energy savings opportunities
Refrigeration-based dehumidification system effectively removes excess moisture
Hot gas reheat - provides reheat using recycled compressor heat
Snap acting / full floating hot gas bypass system provides cooling capacity modulation and evaporator coil freeze protection
Multiple stages of DX cooling to match load requirement
Electronic expansion valves can be optimized to work over a wide range of conditions
Made in the USA
STULZ E2 Control and Monitoring
Precise control of temperature and humidity
Multiple I/O capabilities for all major components to optimize control for energy savings
Supports universal BMS interface for remote monitoring (address readable) and remote control (address writable)
Capable of networking controllers in a workgroup (pLAN) to work as one (no BMS required)
Pre-engineered controls for economizers and adiabatic cooling
