Unit description
2.1
Description of use
The Pfannenberg roof-mounted cooling units of the DTT series are designed for the dissipation of heat from switch
cabinet. The innovative configuration of the climate control circuits prevents cold bridging in the switch cabinet and
the risk of condensate accumulating in the switch cabinet is prevented.
The evaporator unit in the upper section of the cooling unit guarantees problem-free condensate water drainage
without switch cabinet contact.
The cooling units operate with refrigerant rated for very low flammability and which is not harmful for the ozone
layer.
