1

Standard cooling unit

with an attractive price-performance ratio for safe cooling of industrial switch cabinets.
2

Condenser

with large fin spacing enables very long maintenance intervals even without additional Nano coating.
3

Large distance between intake and exhaust vents

for safe air circulation and elimination of hot spots.
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

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

Highest variability

due to cut-out compatibility for 5 performance classes and to Pfannenberg air/water and air/air heat exchangers.
7

Integrated sealing

finished and perfectly mounted.
