Water-cooled chillers with screw compressor:
A new generation of water-cooled chillers based on screw compressors. The range includes models with capacities from 340 to 1780 kW. They are used as central air conditioning systems, industrial refrigeration systems.
Advantages and characteristics:
1. Reliable compressor: Water-cooled chillers are based on highly efficient twin-screw semi-hermetic compressors with asymmetrical tooth profile, manufactured by Hanbell (Taiwan). Regulation of the refrigerating capacity of the screw compressor is automatic. Depending on the heat load on the chiller, the compressor load is staggered by 25%, 50%, 75% or 100%.
2. Built-in controller with color LCD and Touch Screen: Easy to view several parameters simultaneously. Clear and simple visualization: all data are accompanied by graphic information. The controller supports the possibility of redundant circuits, the alarm log, as well as the user settings, the possibility of group control, the possibility of integration into the dispatching system.
3. The electronic controller Carel: In the MDV screw chillers are used common controllers company Carel. Carel company is one of the three world leaders in the production of climate control systems.
4. Distinctive features: EER is 10% higher than the previous generation and reaches a value of 5.96. High reliability, average MTBF over 60,000 hours. Automatic protection against high/low pressure in refrigerant circuit, no water flow, motor overload, phase loss, phase imbalance, defrost protection. Phase rotation, compressor oil level and oil pressure monitoring. Compressor relay protection against abnormal voltages and temperatures.
5. Benefits of installation and maintenance:
- Reduced weight and size, compared to previous generation
- Low depreciation costs when operating the equipment
- Maintenance and repair of the compressor possible
