<Water-cooled screw chiller (double head)
Features of explosion-proof screw chiller
The explosion-proof water-cooled unit of Shenchuangyi Refrigeration is a new type of unit independently designed based on the standard chiller, featuring world-renowned compressors such as Bitzer from Germany, Hanbell from Taiwan, Campanile from the United States, and Sanyo from Japan. By adopting various explosion-proof methods such as flameproof, increased safety, intrinsically safe, positive pressure, oil-filled, sand-filled, spark-free, encapsulated and airtight, the unit can be used in special environments such as flammable and explosive conditions. Different explosion-proof levels can be selected according to the characteristics of the usage environment and different safety requirements.
The performance of the unit has been professionally tested by the detection system and complies with the requirements of standards such as GB/T 18430.1-2007 "Vapor Compression Cycle Water (Heat Pump) Units - Part 1: Water (Heat pump) Units for industrial or commercial and Similar Purposes". The explosion-proof performance of the unit complies with the relevant provisions of standards such as GB3836-2000 "Electrical Apparatus for Explosive Gas Atmospheres" and IEC60079-1991 "Electrical Apparatus for Explosive Gas Atmospheres"
All water chillers of Shenzhen Shenchuangyi Refrigeration Equipment Co., Ltd. are carefully selected with original imported semi-hermetic screw and semi-hermetic reciprocating compressors. The twin-screw with a 5:6 tooth ratio and advanced linear design is low-carbon, energy-saving and environmentally friendly. Good performance and low noise. According to the customer's requirements and the size of the cooling tonnage, single machines or multiple units can be combined. The compressor can automatically alternate operation according to the load changes, balancing the operating hours of each compressor, which greatly extends the service life of the chiller. The trouble-free operation can reach more than 45,000 hours.
High-efficiency and energy-saving evaporator
The copper tubes of the evaporator adopt internal and external threaded reinforced tubes. The surface of the copper tube has threads. The outer surface of the copper tube is smooth and has a good cooling effect. The evaporator cylinder is insulated with 25mm thick PE insulation board, which does not condense and has less cold loss. It is designed with the latest CAD technology and processed by CNC. The structure is compact and the performance is stable.
High-efficiency and energy-saving condenser
The condenser adopts copper tubes imported from abroad in their original form, which are processed into trapezoidal low auxiliary tubes to enhance heat transfer capacity. The surface of the copper tube is smooth, which reduces water pressure and makes it easy to clean and maintain.
Protective device
All the chiller protection system devices of Shenzhen Shenchuangyi Refrigeration Equipment Co., Ltd. include: explosion-proof devices, temperature control switches, anti-freezing switches, fusible plugs, high and low pressure switches, overload protectors, compressor overheat protectors, compressor frequent start protectors and abnormal indicator lights.
Computer control system
Shenzhen Shenchuangyi Refrigeration Equipment Co., Ltd. has developed high-intelligence PLC and PC-level computer control systems, explosion-proof circuit control, which can be remotely monitored and controlled. The operation is simple, and the main unit is connected to the power supply. Low failure rate, high safety factor, and simple installation. The system control can be adjusted in real time, is intuitive and reliable. It features a full Chinese display screen and menu-based keys, allowing for the adjustment of the unit's operating status and providing a convenient operating environment.
