Looking for our BluAstrum chiller compliant with North American codes and standards?
This chiller series is especially characterized by minimal maintenance requirements and an extremely slim model design that fits through standard door-sizes. The little dynamic movement of the chiller components contributes to low maintenance requirements. In addition, the width of only 1.0 to 1.2 m and the resulting small footprint allows simple transport as well as relocation of the chiller and installation in cramped machine rooms.
What are the main highlights and technical details of the GEA BluAstrum chiller?
- Compact screw chiller
- Minimum maintenance requirements
- Extremely compact equipment size
- Cooling capacity 390 - 1,730 kW (R717, 12/6 °C)
- Secondary refrigerant outlet temperature -15/18 °C
- Remote version available (without condenser)
- Casings for touch protection and noise reduction optionally available
