Application description

WARNING
Risk of injury due to impermissible use of the units.
Improper use of units can lead to serious accidents.
• Only use cooling units in stationary operation.
The Pfannenberg roof-mounted cooling units of the DTT-series are designed for heat dissipation from switch cabinets. The
innovative arrangement of the climate circuits prevents a cold bridge to the switch cabinet,; the risk of condensate forming in the
switch cabinet is avoided.
The evaporator unit in the upper section of the cooling units guarantees trouble-free condensate separation without switch
cabinet contact.
• The cooling units operate with refrigerant that is very difficult to ignite and is not harmful to the ozone layer.
• The DTT-cooling units are only approved for stationary operation.
As cooling units of protection class IP 54, the cooling units are largely dust-protected.
Limitation: Dust can penetrate despite this under permanent exposure. The cooling units withstand splash water but not a
continuous water jet.
