Intro

Wall-Air Evolution


Precision air conditioning unit for outdoor installation

Wall-Air Evolution units are compact and weatherproof air conditioning units that are mounted outside the container and so enable the container space to be used to the full.

Solutions for Wall-Air Evolution units

  • Shelter cooling

  • Modular Data Centres

  • For use in telecommunications, infrastructure

Benefits

Benefits

  • Innovative, high-quality components for low energy consumption

  • The units are plug and play and therefore immediately ready for connection and use

  • Automatic restart after power failure

  • Robust and designed for continuous 24/7 operation, 365 days a year

Direct Free Cooling

With Free Cooling the units save up to 84 % on running costs.

FreeCooling

  • Uwe Kudszus, Product Manager

    “With the Wall-Air Evolution device series, we offer compact units for outdoor installation, which are impressively robust and also extremely economical in operation. These features are especially important in the case of wireless telecommunications containers distributed over a wide area, as the service engineers frequently have to travel long distances and the containers have to be cooled with the utmost reliability.“

Advantages of the speed-controlled EC compressor

  • Maximum energy efficiency in partial load mode
  • Constant supply air temperature
  • Refrigerant R410A
  • Integrated compressor soft start
  • Long service life thanks to continuous operation without compressor on/off cycles

 

Efficiency with intelligent air conduction 

Wall-Air Evolution units are available as a displacement version. The displacement principle is especially efficient because of its air conduction method.

Cold supply air flows in close to the ground at low speed. Due to the low speed at which the air is flowing, a "pool" of cold air forms on the floor. This cold air is drawn in by fans integrated in the server rack to a varying extent depending on the heat load, and then expelled upwards as heated air. Because the cold and hot air are prevented from mixing, the displacement unit can draw the circulating air in at 30 °C, instead of 25 °C as was previously the case. This higher temperature level increases the operating hours with Free Cooling.

Features

Features

Controller

Control and monitoring  

The C2020 consists of a controller and an optional operator terminal. The controller controls all the functions of the Wall-Air Evolution unit. The operator terminal, consisting of a keypad and LCD, displays the most important operating states and alerts.

 

Sequencing

  • The C2020 enables up to ten units to be configured in a single air conditioning system. If an individual unit drops out or the heat load rises, the standby unit is switched in for additional support

Night mode

  • Time-controlled limitation of the condenser and evaporator fan speed for quiet operation
  • Energy-saving mode

Monitoring and alarm relaying

  • Via BMS systems (Modbus onboard, further protocols via WIB 1000)
  • Nine potential free contacts are available: Alarms can be assigned a high or low priority
  • Via GSM modem (CompTrol SMS)

Simple configuration and software updates

  • Central configuration of units from a laptop
  • Hardware key for uploading and downloading software without a laptop and/or copying the configuration onto other units

WIB 1000

WIB 1000 is user-friendly and offers easy data exchange, monitoring and worldwide suitability.

  • Ongoing retrieval of data from the controller
  • Ethernet interface
  • Compatible with all common BMS systems
  • Communication via SNMP and HTTP IP protocols
