Brief Description:
This system consists of seven sizes with nominal cooling capacities from 18.9 to 68.4 kW. It has three-phase hermetic reciprocating compressors, operating on R-407C refrigerant with thermal and acoustical insulation.
- Seven sizes with nominal cooling capacities from 18.9 to 68.4 kW
- Split system air conditioners for cooling only and optional heating applications, consisting of the remote air-cooled condensing units 38XTZ installed outside and the 40ABZ/ALZ fan coil units installed inside the building.
- Refrigerant lines (gas and liquid) and electrical cables connect the two units.
- Both units are controlled by a room thermostat.
- Three-phase hermetic reciprocating compressors, operating on R-407C refrigerant.
- Refrigerant-to-air heat exchangers (evaporators and condensers), made of copper tubes and pre-treated water-resistant aluminium fins.
- All-copper refrigerant circuit. Indoor unit refrigerant control using thermostatic expansion valves.
- The units are supplied with a dry nitrogen holding charge.
- Fan control high pressure switch (38XTZ 014).
- High and low pressure switches and filter drier.
- Soldered copper connection lines.
- Complete internal wiring. Thermal-magnetic disconnect switches for compressors and fan motors.
- The indoor units have centrifugal fans driven by three-phase motors with adjustable belt-pulley drives. The outdoor units have direct-drive propeller fans.
- Thermal and acoustical insulation. Flexible shock absorbers in all moving components.
- Pre-painted galvanised sheet steel casings.
- Unit connections to Carrier Comfort Zone II, VVT and TEMP systems (depending on the model).
- Master Link I electronic control (38XTZ 016-024).
