Product Benefits

  1. 1

    Standard cooling unit

    with an attractive price-performance ratio for safe cooling of industrial switch cabinets.

  2. 2

    Tool-free mounting (DTI)

    by 1 person is possible in less than 3 minutes with 55 % lower mounting costs.

  3. 3


    with large fin spacing enables very long maintenance intervals even without additional Nano coating.

  4. 4

    Large distance between intake and exhaust vents

    for safe air circulation and elimination of hot spots.

  5. 5

    Mounting auxiliary edge

  6. 6

    Spring plate (DTI)

    enables 1 person to install the cooling unit. This prevents it from falling out when unsupervised.

  7. 7

    Highest variability

    due to cut-out compatibility for up to 4 performance classes.

  8. 8

    Integrated sealing (DTI)

    finished and perfectly mounted.

  9. 9

    Integrated door and failure contact

    for automatic stand-by mode, if the door is open and opening of a relay as a centralised fault indication, in the event of no voltage supply, temperature too high or too low, temperature sensor is defect or short circuit in the air circuit for example.
