Environmental care
- R-1234ze HFO long-term refrigerant solution with nearly zero global warming potential (GWP < 1) and zero ozone depletion potential (ODP = 0)
- Leak-tight refrigerant circuit
High reliability and easy servicing
- Increased global performance as well as Carrier’s acclaimed product quality and reliability
- Major components are selected and tested with R-1234ze refrigerant to minimize failures possibility, as well as many design choices have been taken in this perspective
- Industrial-type screw compressors with oversized bearings and motor cooled by suction gas
- All compressor components are easily accessible on site minimizing down-time
- Two independent refrigerant circuits (from 1000 kW upwards); the second one automatically takes over, if the first one develops a fault, maintaining partial cooling under all circumstances
- Auto-adaptive control
- Exceptional endurance tests
Safe Design
- Specific polyol ester oil qualified by Carrier for using with HFO-1234ze to guarantee and maintain reliable bearing lubrication
- Specific compressor gaskets compatible with HFO-1234ze, tested and validated by Carrier
- New relief valves designed for operation with HFO-1234ze
- Specific electrical box with increased tightness and integrated blower that maintains positive air pressure to avoid any risk of ignition
- New control algorithms
- Specific documentation that contains all the installation, operation, maintenance and safety instructions
06T twin-rotor screw compressor
- Equipped with bearings with oversized rollers, oil pressure lubricated for reliable and durable operation, even at maximum load
- Optimal adjustment of the compressor cooling capacity
- If a fault occurs, the compressor does not switch off, but continues operation with a reduced capacity (unloaded mode)
- The silencer in the discharge line considerably reduces discharge gas pulsations for much quieter operation
- Condenser includes an oil separator that minimizes the amount of oil in circulation in the refrigerant circuit and redirects it to the compressor function
- SEER 12/7°C up to 7.3
- SEPR 12/7°C up to 9.3
SmartVu™ control
- Intuitive and user-friendly, coloured, 4.3" interface
- 10 languages available
- Easy access to the controller box
- Password protection
- Night-modex
- Energy management
Remote Management (Standard)
- Easily accessed from the internet
- Multiple remote control, monitoring and diagnostic possibilities
- Optional communication gateways
- Condenser pumps control
- Start/Stop of the machine
- Dual set-point management
- Demand limit setting
- Operation visualization
- Alarm visualization
Remote management (EMM option)
- Extended remote control possibilities: room temperature, set-point reset, etc.
- Light-brine solution, down to -3°C
- Lead/lag operation
- Single power connection point
- Evaporator pump power / control circuit
- Evaporator dual pumps power / control circuit
- Condenser pump power / control circuit
- Condenser insulation
- Service valve set
- Lon, J-Bus or BacNet gateway
