EcoAir


Experience at the service of Data Centers

The new EcoAir3 models are designed for small or medium server rooms with a heat load of up to 35 kW.

Solutions for EcoAir

  • Data Center

Benefits

Benefits

  • extreme compactness and flexibility

  • maximum energy efficiency

  • accurate control of environmental parameters and business continuity

Air supply where necessary

EcoAir3 is available in 3 versions:
• Upflow (DXU, DIU, DWU);
• Downflow (DXD, DID, DWD);
• Displacement (DXF, DIF, DWF) with frontal and lateral
air supply, or frontal air supply with a grill with
adjustable fins.
For each of the three configurations our free cooling
module is available.

Energy Efficiency

SEC.blue

The new electronic control STULZ SEC.blue regulates the EcoAir3 components (EC fans, electronic expansion valve and EC compressor, if present) and optimises the operating modes.

The average EER of direct expansion units with ON/OFF compressor is over 3.3. 

The efficiency of units with EC compressor is even greater at partial loads.

EC Compressor (optional)

 
EC compressors continuous monitoring guarantees:
• maximum efficiency at partial load; 
• higher precision in supply air temperature control, offering a quick response to variations in the heat load;
• integrated soft start to suppress locked rotor current;
• long service life thanks to the continuous operation, which reduces  the number of on/off cycles

Fans with high efficiency EC motors


• respond continuously to changing power requirements; 
• switch to in energy saving mode at partial loads;
• allow reduced energy 
consumption and offer low noise  level compared to the conventional fans;
• accept a wider range of  voltage supply;
• compliant to ErP2015 directive
