ORCA and NARWHAL recirculating chillers from Grant are stand-alone closed circulators providing powerful, accurately controlled cooling for analytical techniques and instruments where an optimum operating temperature is required.
Features:
- Precise temperature control
- Low coolant consumption (use: Deionised water for range +5 to +40°C, or Deionised water/glycol mixture for –10 to +5°C)
- Settable high temperature warning and low-level alarms
- Over- or under-temperature cut-outs
- Advanced refrigeration automatically adjusts to heat loads, minimising power required
- Flow fail device cuts power if no liquid in system
- 1-999 minute timer
- Digital temperature display
- Noise: 50dB
