China Factory Suppliers PC-WC Series Air Cooled Industrial Cold Water Machine for Low Temperature Cooling Solutions
Design advantages
1. Compact Structure & Smooth Operation
Condenser and evaporator units use efficient heat transfer tubes. The host features imported, highly efficient hermetic scroll compressors, offering a compact structure, small size, and lightweight installation advantages. With fewer moving parts and flexible operation, it guarantees high energy efficiency, low noise, low operating costs, and high reliability. The continuous operation without pulse ensures stable performance, low noise, and minimal vibration. Efficiency is 20%-30% higher than reciprocating compressors.
2. Improved Energy Control System
Air conditioning units start and stop according to load changes for optimal energy efficiency. The computer control system dynamically adjusts energy output based on the client's thermal load changes. By monitoring the difference between the actual and set loads via microcomputer, the system quickly determines the required energy. Multi-system setups optimize output to ensure the lowest energy consumption, reflecting excellent performance at both full and partial loads.
3. Simple & Intuitive Control
Equipped with a microcomputer program controller (digital display) allowing users to start the unit with a simple touch of a button. The panel displays operating status and parameters in clear text at a glance. No professional training is required for normal operation. The system precisely controls temperature to 1℃ (special requests up to 0.1℃) within a set range of 5℃-50℃, facilitating direct analysis of the unit health.
4. Microcomputer Protection Features
Comprehensive protection features include compressor coil overcurrent protection, pump overcurrent protection, cold water flow switch, low cooling protection, high-temperature water protection, compressor overload protection, frequent start/stop protection, abnormal voltage protection, and high/low pressure protection.
5. Multiple Protection, Safe & Reliable
In addition to the internal compressor protection module providing over/under voltage, phase failure, and overload protection, the system integrates refrigeration pressure control units and other safety devices to make operation completely foolproof.
6. Optimized Low-Noise Design
Optimized refrigeration efficiency and design to reduce noise as much as possible, meeting strict environmental requirements. Air-cooled chiller pumps are easy to move and operate without requiring the installation of cooling towers.
7. Easy to Install
All components are pre-installed and run-tested at the factory, with refrigerants and refrigeration oils fully pre-charged. Users simply need to connect the water circuit and electrical circuit to put the system into immediate use, minimizing installation and commissioning time.
