- High capacity twin screw compressors offer reliability and flexibility, with staged capacity control.
- Low GWP R513A refrigerant.
- 8 stages of cooling across two compressors for more precise capacity match.
- Dual independent refrigeration circuits for resilience.
- Efficient shell and tube evaporator with freeze protection offers high evaporating temperatures.
- Economizers, each with dedicated EEV, to enhance compressor performance at full and part load operation.
Chilled Water System
- Up to 95% free-cooling via enhanced economizer technology that increases free cooling envelope, even in high ambient regions.
- Glycol containment system protects chiller while ensuring 100% chilled water delivery to the data center, increasing heat exchange efficiency.
- Increased operational evaporating temperature range allowing supply water temperatures to be increased, thus raising the free cooling threshold and giving enhanced compressor efficiency and reduced power input.
- Large surface area condenser coil with enhanced tube and fin for improved heat exchange and low noise.
- On-board variable speed pump, ensuring supply is perfectly matched to load while maintaining water-side TD and saving on external plant requirements.
- On-board active harmonic filtration, ensuring a clean power supply to the data center, while saving on external plant requirements.
- Automatic rescheduling of chilled water.
- Enhanced controls including fast start, load limiting and intelligent management of compressors, refrigerant and pumps.
- Modem link for remote monitoring
- Latest fan technology reduces sound and power input.
- Robust construction with acoustic insulation features, that can perform in a wide range of climates / settings.
- Corrosion-resistant condenser coils for aggressive atmospheres
- Optional Coil guards to help prevent fin damage
