Product Description
The Ruidong water-cooled scroll chiller and heat pump is designed with a scroll compressor, offering clients the flexibility to select 1 to 4 compressors based on their building size and requirements. This equipment is equipped with a shell and tube condenser, evaporator, and control system. It is specifically designed for efficient cooling and heating of large-scale commercial buildings like malls, offices, workshops, hotels, and hospitals.
We offer a range of standard water-cooled scroll chillers with various capacities:
Cooling capacity ranges from 70KW to 280KW.
Temperature control range is from 5℃ to 30℃, with an accuracy of ±1℃.
These chillers are suitable for water source working condition.
1. Our water-cooled scroll chillers are equipped with a smart microprocessor controller that provides comprehensive monitoring and precise temperature control. The controller displays information in English and alerts users to any abnormal situations. An RS-485 communication protocol supported version is also available.
2. To ensure durability and stability, we use high-quality Schneider Electric parts such as AC contactors, breakers, and thermal relays. These components adhere to higher standards and contribute to a longer service life.
3. Our chillers feature Danfoss or Copeland hermetic scroll compressors. Through our long-standing collaboration with compressor manufacturers, we have optimized the efficiency of these compressors.
4. The heat exchanging components of our chillers are thoughtfully designed. The generously sized shell and tube condenser reduce the risk of blockages caused by poor water quality. Additionally, our chillers incorporate a high-quality brazed plate heat exchanger for enhanced heat exchanging efficiency.
5. We have integrated a hydronic module into our water-cooled industrial chiller. This module includes a buffer tank and a large-flow circulation pump, making installation and operation hassle-free. Inlet and outlet water bypass valves are also provided for easy water pressure adjustment. Furthermore, the chiller is equipped with a water tank sight glass, allowing users to check the water level and quality at a glance.
