The range of compressor-condensing units with cooling capacities from 51 kW to 160 kW is manufactured in Italy and is introduced in addition to the existing range of compressor-condensing units with cooling capacities from 2.6 to 45 kW. Condensing units LUE-...TC2/LUE-...C2/LUE-...C4 are supplied with complete freon piping.
The housing
Made of painted galvanized steel. Panels outside coated with plastic (PVC) film, mounted on aluminum profiles. Resistant to atmospheric precipitation.
Compressor
Sanyo or Bitzer. Hermetic scroll compressors with internal thermal protection and crankcase heating. Supplied filled with oil and with anti-vibration inserts.
Freon circuit
Consists of filter-drier, sight-glass with moisture indicator, solenoid valve, TRV, liquid line shutoff valve, high and low freon pressure protection relay.
Axial Fan
Axial fan with guard grille directly coupled to IP54 protected motor with internal thermal protection
Control Box
Complies with IEC 204-1/EN60204-1 standards, complete with contactors, protection of all components and interlocked operation when the panel door is open.
