Introduction of water-cooled unit of screw freezer

Screw chillers and low-temperature chillers are special chillers designed for special low-temperature environments. Their super refrigeration capacity provides a reliable guarantee for various low-temperature environments in commercial places such as hotels, restaurants, supermarkets, etc., such as food preservation, large cold storage, freezing, refrigeration, ice making, food processing, freezing / refrigeration, pharmaceutical, chemical and other low-temperature environments.

1. The product series are complete, including high temperature (-5 ℃), medium temperature (-10 ℃) and low temperature (-15 ℃).

2. The structure is highly optimized, and the heat exchange plate is used to support the body, which is simple, compact and practical.

3. The high-quality screw compressor is perfectly combined with the heat exchanger, and the energy efficiency ratio is as high as 4.5.

4. Four level or stepless capacity control to accurately match load changes.

The chiller has small volume, large refrigerating capacity, excellent low-temperature performance, reliability and durability. The product is designed according to the characteristics of industrial application, with built-in low-temperature circulating water pump and stainless steel freezing water tank, which is extremely convenient to use. All materials in contact with water are made of anti-corrosion materials to effectively prevent rust and corrosion. Microcomputer led quantity controller has the functions of temperature display, temperature setting, automatic regulation of chilled water temperature and compressor delay protection. Select good electrical components such as contactors and relays, equipped with perfect indicator lights and switches, the operation is clear at a glance, the built-in electronic water level indication and alarm device, low water level automatic alarm, the operator can master the water level of the chilled water tank through the control panel and make up water in time, the unique modular design, the system of each compressor is safe and independent, even if a system has problems, It will not affect the normal operation of other systems.

Introduction of water cooling unit
