China Suppliers Factory PC-WC Series Air Cooled Industrial Cold Water Machine for Low Temperature Applications
Design Advantages
1. Compact Structure & Smooth Operation
Condenser, evaporator units are used in efficient heat transfer tubes, the host selection of imported and efficient hermetic scroll compressor, has a compact structure, small size, lightweight, small, and many other installation location advantages. Hermetic scroll compressor fewer moving parts, compressor using flexible compressor, high energy efficient, low noise, low operating costs, the buck does not automatically uninstall direct abrasion and high reliability. Since no pulse compressor is continuous, so the unit has a stable performance, low noise, small vibration, smooth running characteristics. 20%-30% higher than the efficiency of the reciprocating compressor.
2. Improve the Energy Control System
Carry conditioning units start and stop according to load changes, more energy-efficient. Running, the computer control system will be based on the client to change the thermal load changes energy output of the unit. Difference between the actual load and the setting of the user measured by monitoring the microcomputer to determine the required energy quickly. And more than one system, the best way to optimize the output of cold work when the least energy consumption, not only reflects the excellent performance at full load, also has a high operating efficiency even at partial load.

Panel at any time to display operating status of the unit, and ways to display text form parameters at a glance. No professional can normally use, can precisely control temperature 1℃ (special request accuracy up to 0.1℃), set the temperature range 5℃-50℃, can be directly analyzed the health unit.
4. Microcomputer Protection Features
A compressor coil current is too high to protect, the pump current is too high, cold water flow switch, cold is too low protection, high temperature water temperature protection, compressor overload protection, start and stop frequently to protect, abnormal voltage protection, high and low voltage protection and other protection.
5. Multiple Protection, Safe & Reliable
The unit in addition to the internal compressor protection module provides ultra under voltage, phase failure, overload protection and other functions outside of the compressor, the pressure of the refrigeration system control units and other devices to make foolproof.
6. Optimized Environmental Efficiency
Refrigeration efficiency easy to move as much as possible to reduce noise and meet environmental requirements (without mounting tower pumps, Air-cooled chiller pumps easy to move without assembling towers).
