DTI/DTS 6301

εCOOL cooling units 1500 W

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

  • robust: steel cover, easily paintable
  • top EER (energy efficiency ratio)
  • energy efficient: reduced CO2 emissions = environment-friendly
  • condenser with large fin spacing for highly effective protection in 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
  • exceptional serviceability
  • new USB port (MC version) for easy retrieval of parameter settings/history (Pfannenberg εCOOL-Plant software necessary)
  • optional filter (easy to retrofit)
  • energy-saving mode by default integrated into the Multi Controller

Introducing the εCOOL cooling units (DTI/DTS/DTT 6xxx).

Product Benefits

  1. 1

    Tool-free mounting (DTI)

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

  2. 2

    Integrated sealing (DTI)

    finished and perfectly mounted.

  3. 3

    High energy efficiency ratio (EER)

    for up to 43 % energy savings and operating costs reduction.

  4. 4

    Large distance between intake and exhaust vents

    for safe air circulation and elimination of hot spots.

  5. 5


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

  6. 6

    Optional pre-filter

    upgradable with aluminium, nonwoven or fluted filter, for the application of the cooling units in different ambient conditions.

  7. 7

    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.

  8. 8

    Spring plate (DTI)

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

  9. 9

    Highest variability

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

  10. 10

    Additional temperature sensor

    In the Multi Controller (MC) model allows the deactivation of the internal fan and condensate evaporation for additional 10 % energy savings and service life extension of the fan.

  11. 11

    Interface to use εCOOL-Plant

    at the Multi Controller (MC) model with operating hours counter and error history observation for preventive maintenance processes and exact error analysis.

  12. 12

    Integrated condensate evaporation

    no puddles of water under the device for increased operation safety.
