The system, providing water cooling within the temperature range of 7-35 °C, allows for the adjustment of low cooling temperatures based on user preferences. Thanks to microcomputer technology, it can precisely control the system temperature with an accuracy of 1 °C. Additionally, the overloading protection device used for the compressor and pump extends the service life of these components. Various protection features, including antifreeze, low and high-pressure protection, and flow protection, ensure system safety. The stainless steel water tank is equipped with heat insulation. The cooling pipe line, enhanced with an insulation layer, optimizes cooling efficiency. The outer coating and condenser demonstrate high efficiency in heat exchange. Another feature of the system is the low-speed and quiet ventilation fan. The ventilation fan operates in conjunction with the compressor, effectively saving electrical energy.
