Description
Low energy consumption
- SEPR up to 8.0 and SEER up to 7.2
- 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 utilization of the evaporator heat exchange surface
- Economizer system with electronic expansion device for increased cooling capacity (30XW-P)
Low operating sound levels
- Silencers on the compressors discharge line
- Silencers on the economizer return line
- Acoustic insulation on the components that are most subjected to radiated noise
- Option 257 further reduces the global unit sound level
Easy and fast installation
- Compact design
- Simplified electrical connections
- Simplified hydraulic connections
- Fast commissioning
Environmental care
- R-134a refrigerant
- Leak-tight refrigerant circuit
High reliability and easy servicing
- Increased global performance
- Major components are selected and tested 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
- Two independent refrigerant circuits
- Auto-adaptive control
- Exceptional endurance tests
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
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)
- 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
- Equipped with an RS485 serial port that offers multiple remote control, monitoring and diagnostic possibilities
- Communicates with other building management systems via optional communication gateways
- The following commands/visualizations 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 visualization: Indication if the unit is operating or if it is in stand-by (no cooling load)
- Alarm visualization
- Medium- or low-temperature brine solution
- Light-brine solution, down to -3°C
- Unit supplied in two assembled parts
- Master/slave operation
- Single power connection point
- No disconnect switch, but short circuit protection
- Condenser insulation
- J-Bus gateway
- BacNet over IP gateway
- Lon gateway
- High condensing temperature
- Leak detection
