Product overview
Marine Water Cooled Scroll Chiller is a seawater-resistant industrial refrigeration unit designed for shipboard and offshore cooling systems. It uses hermetic scroll compressors to provide chilled water under continuous-duty conditions.
Features
- Four Sanyo hermetic scroll compressors provide staged capacity control, improving energy efficiency and reducing compressor wear during partial-load operation.
- Water-cooled condenser design uses seawater or freshwater cooling loops, delivering stable performance in high ambient marine environments.
- Emerson expansion valves and Siemens electrical controls ensure precise refrigerant regulation and reliable system operation.
- Integrated pump and 200 L insulated water tank simplify onboard installation and reduce external piping requirements.
- Multi-level protection system includes phase loss, overload, high/low pressure, coil overheat, and anti-freeze safeguards to protect critical components.
- Compact marine-ready structure (2200 × 600 × 900 mm) minimizes equipment footprint while maintaining easy maintenance access.
