- COP of up to 6.7 and SCOP up to 6.5
- Twin-rotor screw compressor equipped with a high-efficiency motor and a variable capacity valve that permits exact matching of the cooling capacity to the load
- Flooded multi-pipe heat exchangers for increased heat exchange efficiency
- Electronic expansion device permitting operation at a lower condensing pressure and improved utilisation of the evaporator heat exchange surface
- Economiser system with electronic expansion device for increased cooling capacity
- Silencers on the compressors discharge line
- Silencers on the economiser return line
- Acoustic insulation on the components that are most subjected to radiated noise
- Option 257 further reduces the global unit sound level
- Compact design
- Simplified electrical connections
- Simplified hydraulic connections
- Fast commissioning
- R-1234ze HFO long-term refrigerant solution with nearly zero global warming potential (GWP < 1) and zero ozone depletion potential (ODP = 0)
- R-515B future-proof A1 refrigerant
- Leak-tight refrigerant circuit
- Increased global performance as well as Carrier's acclaimed product quality and reliability
- Major components are selected and tested with R-1234ze and R-515B refrigerant to minimise 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 minimising 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
- Specific polyol ester oil qualified by Carrier for using with HFO-1234ze or R-515B to guarantee and maintain reliable bearing lubrication
- Specific compressor gaskets compatible with HFO-1234ze or R-515B, tested and validated by Carrier
- New relief valves designed for operation with HFO-1234zeor R-515B
- 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
- 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 minimises the amount of oil in circulation in the refrigerant circuit and redirects it to the compressor function
