X-CUBE ROOMAIR-B-ZAB/SEK   

Supply and extract air unit with heat exchanger and heat recovery, secondary air option, for installation under the sill

Ready-to-operate decentralised ventilation unit that provides good comfort levels, used for the ventilation and extract ventilation of rooms

  • Acoustically optimised EC fans with low specific fan power, SFP = 1 to EN 16798-3
  • Plate heat exchanger for heat recovery (air/air), including bypass damper with electric actuator (open-close)
  • Heat exchanger for heating and cooling as 2-pipe or 4-pipe system
  • Reduction of fine dust and pollen contamination due to integral filters that conform to VDI 6022 – F7 fresh air filter and G3 extract air filter
  • Inspection panel simplifies filter change and cleaning of the heat exchanger
  • Condensate drip tray with condensate drain
  • Motorised shut-off dampers, normally closed (NC)
  • Automatic switching to secondary air mode (based on air quality)


Optional equipment and accessories

  • Modular control system FSL-CONTROL II, specially for decentralised ventilation systems
  • Demand-based fresh air volume, free cooling and night purge, depending on control strategy
  • Various fixing systems to fix the unit to the floor or wall
  • Variable heat recovery
  • Powder-coated RAL 9005

Application

Application

  • Ventilation of rooms, preferably rooms with a depth up to 6 m
  • 2-pipe or 4-pipe heat exchangers enable good comfort levels
  • Inducing displacement flow
  • Energy-efficient solution since water is used for heating and cooling
  • For new buildings, refurbishment projects and revitalisation projects
  • Installation under the sill
  • Typical installation locations include offices and meeting rooms

Special characteristics

  • Recuperative heat exchanger for heat recovery, including bypass damper with variable electric actuator (open-close)
  • Mechanical self-powered volume flow controller for limiting the fresh air flow rate
  • Heat exchanger as 2-pipe or 4-pipe system, with G½" union nuts and flat seals
  • Meets the hygiene requirements of VDI 6022
  • Filter class: F7 for fresh air, G3 for extract air
  • Easy filter change with quick release fasteners, no tools required; easy access to the heat exchanger for cleaning
  • Condensate drip tray with condensate drain
  • Compact construction, hence particularly suitable for refurbishment projects
  • Demand-based ventilation is possible by means of monitoring the room air quality and with dedicated control equipment
  • 4 levelling feet
  • Motorised shut-off dampers for fresh air and exhaust air, normally closed (NC) in order to prevent uncontrolled airflows and the carry over of smoke
  • Automatic switching to secondary air mode (only with an air quality sensor) if the room air quality (measured with the integral VOC sensor, for example) is between the previously defined range. The fresh air damper closes, the self-powered secondary air damper opens and the extract air fan is switched off. The unit always starts in secondary air mode, which is more energy efficient.

Version as SLAVE DEVICE

Identical to the MASTER DEVICE, as described above, but with the following deviations:

  • No room air quality measurement in the unit
  • No connection option for room control panels
  • No outdoor temperature detection in the outdoor air
  • No connection to on-site bus communication possible
  • Pre-assembled self-sufficient control system for decentralised façade ventilation units in SLAVE construction


Commissioning/parameterisation of the decentralised ventilation units without integration into an on-site MCE/BACS



  • Visual inspection of the device connections on site for compliance with the respective installation specifications from the installation and configuration instructions: air connections, heating/cooling connection, electrical connections, integration into the installed outer casing, connections of external components
  • Checking and, if necessary, adapting the project parameters pre-set in the factory with regard to customer-specific adaptations
  • Functional test of the individual components (control elements, fans, valves, dampers, sensors)
  • Checking the project-specific control functions including any special functions such as volt-free switch contacts
  • Documentation of the device settings and service work in a service report. The service report must be signed by your company or representative as the client.
  • Invoicing is done as a flat rate, derived from the number of units and distance.

  • Visual inspection of the device connections on site for compliance with the respective installation specifications from the installation and configuration instructions: air connections, heating/cooling connection, electrical connections, integration into the installed outer casing, connections of external components, connections of MCE/BACS
  • Checking and, if necessary, adapting the project parameters pre-set in the factory with regard to customer-specific adaptations
  • Functional test of the individual components (control elements, fans, valves, dampers, sensors)
  • Checking the project-specific control functions including any special functions such as volt-free switch contacts
  • Function test of the communication to the MCE/BACS in cooperation with the controls provider:
    • Checking that the on-site settings comply with the specifications in the installation and configuration instructions
    • Input test of the data points sent on site
    • Output test of the output data points
    • Trial operation of the operating states that can be switched by the MCE/BACS
  • Documentation of the device settings and service work in a service report. The service report must be signed by your company or representative as the client.
  • Invoicing is done as a flat rate, derived from the number of units and distance.


 



Instruction in operation and maintenance



  • One-time instruction for the operation of the decentralised ventilation units consisting of:

    • Description of the equipment functions on the unit that has already been put into operation
    • Description of the room control panel and the room conditions that can be influenced by it
    • Description of the maintenance work
  • Invoicing is done on a flat-rate basis. The instruction is carried out by the responsible sales representative
