Cooling units DTI Video

This video shows the easy installation of Pfannenberg's DTI (partially recessed) cooling units from the ICS series. The cooling units have been designed to satisfy all requirements for partially recessed installation for every size of electrical enclosure.

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

    Condenser

    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

    allows the cooling unit to stand freely when unpacking and before installing, and prevents the unit from slipping out uncontrollably during installation into the mounting cut-out by 1 person.

  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

    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.
