  • Page 5: System Overview

    System Overview DL Series Introduction The DL Series hybrid humidifier is based exclusively on the advantages of the two humidification principles of atomization and evaporation. The humidifying water is atomized by stainless steel atomizing nozzles at low pressure. The atomizing nozzles have an adjustable spray output and are optimally distributed over the entire cross-section of the device.

    Design Requirements The following parameters will be needed when sizing and selecting your Condair DL humidification system: Item # Required Parameter Why is this needed? Air volume Required for humidification capacity calculation. Used to calculate duct velocity and determine if droplet sepa- rator is required: No droplet separator required up to 492 ft/min (2.5 m/s)

    Avoid installation where there is chance of unit freezing, this can cause damage to the system. Heat treating of water lines going to the Condair DL is not permitted for hygiene reasons. The length of the spray circuit lines between central unit and housing feed throughs of the duct are as short as possible (max.

  • Page 29: Appendix F - Common Positioning Mistakes

    Appendix F – Common Positioning Mistakes Position of spray circuit connectors Problem: Spray circuit lines sag under the door. Spray circuit lines are not completely drained by gravity. Standing water remains in the spray circuit lines. Remedy: Lower central unit in rack one position (-4" (-100 mm)) down that the spray circuit connections are below the lowest point of the spray line routing to create a constant downslope.
  • Page 30 Position of spray circuit connectors Problem: Spray circuit connections of central unit are above wall feed throughs. Spray lines are not completely drained by gravity. Standing water remains in the spray lines. Remedy: Position wall feed throughs further up (but still below lowest connector of nozzle grid) or posi- tion the central unit further down to create a gradient (according Fig.
  • Page 31 Remedy: Modify central unit from spray circuit connection side left to the spray circuit connection side right (according Fig. 17 Fig. 18). Modification is described in the Condair DL installation manual. Fig. 21: Rack Position Fault Example 3 2611853-A EN 2502 Appendix...
