Product model:

The OZ series water-cooled screw type low-temperature chiller is a series of products independently developed, designed, and produced by ONTAZ based on the original water-cooled screw unit, targeting production processes such as freezing, refrigeration, and industrial cooling that require low-temperature treatment. The new generation of screw type low-temperature chiller, which retains the traditional advantages of the original unit and has been further improved and developed. There are 126 standard specifications for the unit, with a cooling range from 42100kGal/h to 2165500kcal/h and a chilled water temperature adjustment range of -10~10 ° C.

Introduction to water-cooled screw type low-temperature chiller unit

All water-cooled screw refrigeration units are selected from original imported branded semi closed screw and semi closed reciprocating compressors. Twin screw 5:6 gear ratio and advanced linear design, low-carbon, energy-saving and environmentally friendly; Good performance and low noise. According to customer needs and the size of the cooling capacity, single or multiple machine combinations can be used. The compressor can automatically alternate operation according to load changes, balancing the operating hours of each compressor, greatly extending the service life of the chiller unit, and achieving more than 45000 hours of fault free operation. In addition to standard specifications, various special units can also be customized according to user requirements. The unit is suitable for food, chemical, battery, refrigeration, and various places with special low temperature requirements.

Characteristics of water-cooled screw type low-temperature chiller:

The intelligent unit adopts an intelligent microcomputer touch screen control system, providing the most thoughtful service and simplest maintenance information, and can be connected to the user's central control system to comprehensively monitor the operation of the unit.

Efficient and advanced high-performance twin-screw compressors are matched with efficient condensers and evaporators, high-quality cooling copper pipes, and comply with relevant national standards.

The safety unit is equipped with multiple safety protection measures to ensure the safe use of customers.

The design of the unit is reasonable and aesthetically pleasing.

Configuration of water-cooled screw type low-temperature chiller:

The evaporator copper tube adopts an imported internal and external threaded reinforced tube, and the condenser condenser adopts an imported internal copper tube, which is finely processed into a trapezoidal tube to enhance thermal conductivity. The evaporator cylinder is insulated with a 25mm thick PE insulation board, which does not condense and has minimal cooling loss. It is designed using the latest CAD technology and processed by CNC machining, with a compact structure and stable performance. The surface of the condenser copper tube is smooth, which reduces water pressure and is easy to clean and maintain. The outer surface of the copper tube is smooth, with threads and good cooling effect.

Industrial chiller electrical control:

By embedding intelligent controllers into the control system, the operation is simple and easy to understand, enabling remote control and monitoring to reduce failure rates, improve safety factors, and be easy to install. The system is equipped with anti freezing switches, temperature control switches, fusible plugs, overload protectors, high and low pressure switches, and other devices. The system control can be adjusted in real time, intuitive and reliable, with a fully Chinese display screen and menu style buttons that can adjust the operating status of the unit, providing a convenient operating environment. In addition, the equipment is equipped with a compressor overheat protector, a compressor frequent start protector, and an abnormal indicator light.
