China Suppliers Factory PC-WC Series Air Cooled Industrial Cold Water Machine - Adjusts from -30°C to +5°C
Design Advantages
Compact & Smooth Operation
Condenser and evaporator units use efficient heat transfer tubes. The host features imported, highly efficient hermetic scroll compressors, offering compact structure, small size, and lightweight installation. With fewer moving parts and flexible compression technology, it delivers high energy efficiency, low operating costs, low noise, and minimal vibration.
Energy Control System
Conditioning units automatically start and stop based on load changes to maximize energy savings. The microcomputer control system monitors the difference between actual load and user settings to adjust energy output dynamically. Multi-system setups optimize output to ensure minimal energy consumption at both full and partial loads.
Simple & Intuitive Interface
Equipped with a microcomputer program controller (digital display), allowing users to easily start the unit by touching the panel. The screen displays real-time operating status and parameters in text format. Temperature can be precisely controlled to 1℃ (special requests up to 0.1℃) within a range of 5℃-50℃.
Microcomputer Protection
Features comprehensive protection functions: compressor coil overcurrent protection, pump overcurrent protection, cold water flow switch, low-temperature protection, high-temperature water protection, compressor overload protection, frequent start/stop protection, abnormal voltage protection, and high/low pressure protection.
Multiple Safeguards
In addition to the internal compressor protection module (providing under-voltage, phase failure, and overload protection), the refrigeration system pressure control units and safety devices ensure foolproof and reliable operations under all working conditions.
Optimized Mobility
Designed to maximize refrigeration efficiency while reducing noise to meet strict environmental requirements. Air-cooled chiller pumps are highly mobile and easy to move without the need to assemble cooling towers.
Easy Installation
All components are fully installed and run-tested at the factory, including the pre-filling of refrigerants and refrigeration oils. Users simply need to connect the waterway and electrical circuit to put the unit into immediate use, reducing setup time.

Notes
1. Cooling capacity basis: Chilled water inlet and outlet water temperature 12℃/7℃; cooling air inlet temperature of 30℃/35℃.
2. Scope of work: Chilled water temperature range: 5℃ to 35℃; chilled water out of the water temperature: 3℃ to 18℃.
3. Ambient temperature limits: In condensing, the ambient temperature should not be higher than 35℃ (non-standard chilled ambient temperature maximum temperature of 5℃ requires custom ordering).
4. Customization: These models can be customized according to specific customer production requirements.
5. Specifications changes: Dimensions and specifications listed above are subject to change without prior notice.
