DTI/DTS 9241

Cooling units 1000 W

DTI: for partially recessed mounting in the door or side
DTS: for outer mounting on the door or side

  • Integrated Cooling System©: one mounting cut-out for 5 cooling performance ratings, mounted by 1 man in 2 minutes.
  • Condenser with 3 mm fin spacing, highly effective protection against strongly contaminated ambient air
  • Large distance between intake and exhaust vents, safe circulation within the electrical enclosure due to long passage of air, therefore hot spots are eliminated.
  • Integrated fault and door contact.
  • Optionally available with integrated condensate evaporation system.

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

    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.
