- Low energy consumption
- High reliability
- Easy and fast installation
- Minimised operating sound levels
- Environmental care
- Designed to support green building design
Low energy consumption
- Designed for high performance both at full load and at part load
- SEPR up to 8.07 and SEER up to 8.43
- Inverter-driven twin-rotor screw compressors allow precise capacity matching of building load changes and significantly reduce unit power input, especially at part-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
- optimised electrical performance
High reliability
- Offers increased global performance
- Inverter-driven screw compressors with oversized bearings and motor cooled by suction gas. The inverter is optimised for each compressor motor to ensure reliable operation and easy maintenance
- Two independent refrigerant circuits
- Auto-adaptive control
- Exceptional endurance tests
Easy and fast installation
- Compact design
- Simplified electrical connections
- Simplified water connections
- Fast commissioning
Environmental care
- R-134a refrigerant
- Leak-tight refrigerant circuit
Minimised operating sound levels
- Low noise Greenspeed® variable-speed fans
- The inverter technology used for the compressor motors minimises noise levels at part load operation
- Silencers on the compressor discharge line
- Sound insulation on the components that are most subjected to radiated noise
- Option 257 further reduces the global unit sound level
Designed to support green building design
A green building is a building that is environmentally sustainable and has been designed, constructed and is operated to minimise the total impact on the environment. The resulting building will be economical to operate, offer increased comfort and create a healthier environment for the people who live and work here, increasing productivity. The air conditioning system can use between 30 and 40% of the annual building energy consumption. Selection of the right air conditioning system is one of the main aspects to consider when designing a green building. For buildings with a variable load throughout the year, 30XW-V unit offers a solution to this important challenge.
Inverter-driven Thunderbolt screw compressor
- Advanced control algorithms combine inverter frequency output with motor input logic to minimise mechanical part stress, resulting in best compression performance and high chiller reliability
- Equipped with bearings with oversized rollers, oil pressure lubricated for reliable and durable operation, even at maximum load
- Screw compressors use positive displacement principle to compress gases at higher pressure. As a result, in case of exceptional high temperature condenser side, the compressor does not switch off, but continues operation at 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
Touch pilot control
- An intuitive user-friendly coloured 7" interface
- Direct access to the unit's technical drawings and the main service documents
- Screen-shots with coincisive and clear information in local languages
- Complete menu, customised for different users
- Safe operation and unit setting: password protection ensures that unauthorised people cannot modify any advanced parameters
- Simple and "smart" intelligence uses data collection from the constant monitoring of all machine parameters to optimise unit operation
- Energy management
Remote management (standard)
- Units with Touch Pilot 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/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)
