Features & Benefits
- 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
- PUREtec™ R-1234ze long-term refrigerant solution
- R-515B future-proof A1 refrigerant
- Leak-tight refrigerant circuit
- Increased global performance
- 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
- Two independent refrigerant circuits
- 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-1234ze or 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
Controls
- Intuitive and user-friendly, coloured, 4.3" interface
- 10 languages available
- Easy access to the controller box
- Password protection
- Night-modex
- Energy management
- Units with SmartVu™ control can be easily accessed from the internet, using a PC with an Ethernet connection. This makes remote control quick and easy and offers significant advantages for service operations
- Communicates with other building management systems via optional communication gateways
- The following commands/visualisations are possible from remote connection:
- Condenser pumps control: a digital input allows verification of condenser water flow (the flow switch must be supplied by the installer)
- Start/Stop of the machine
- Dual set-point management through a dedicated contact is possible to activate a second set-point (example: unoccupied mode)
- Demand limit setting: to limit the maximum chiller capacity to a predefined value
- Operation visualisation: Indication if the unit is operating or if it is in stand-by (no cooling load)
- Alarm visualisation
- Condenser pumps control: a digital input allows verification of condenser water flow (the flow switch must be supplied by the installer)
Carrier meeting the challenge of efficiency and climate change with PUREtec™ range.
Four years after the first installation of a water-cooled screw chiller based on HFO refrigerant in Europe, Carrier’s AquaForce chiller units with PUREtec refrigerant have been installed in more than 500 projects throughout the region, in multiple applications such as industrial, data centers, district heating, and healthcare.
