Product Benefits

  1. 1

    Standard cooling unit

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

  2. 2


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

  3. 3

    Large distance between intake and exhaust vents

    for safe air circulation and elimination of hot spots.

  4. 4

    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.

  5. 5

    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.

  6. 6

    Highest variability

    due to cut-out compatibility for 5 performance classes and to Pfannenberg air/water and air/air heat exchangers.
