Detailed Product Description: | Hua Dexin screw water cooled chiller, as follows: water-cooled screw chillers using imported semi-hermetic screw compressor, good performance, low noise. Hua Dexin water-cooled screw chillers according to the needs of customers and the cold tonnage size, using a combination of single or multi-; compressor according to load changes, automatically operate alternately, balanced compressor run hours, greatly extending the chillers period of use. Hua Dexin water-cooled screw chiller condenser brass external thread intensifier tubes, brass threaded surface enhanced heat transfer capability, end cap design easy cleaning and maintenance. Hua Dexin water-cooled screw chiller shell and tube evaporator tube body 25mm thick PE insulation board insulation, non-condensing and cooling loss. Hua Dexin water-cooled screw chiller temperature control switch, antifreeze switch fusible plug, high and low pressure switch, overload protection, compressor overheating protection, compressor the frequent starts protector and unusual light. Intelligent microcomputer touch screen + PLC control system; Hua Dexin water-cooled screw chillers can do remote monitoring and control, simple operation, the host power supply connection; low failure rate, high safety factor, installation is simple; system control real-time adjustments , intuitive and reliable. Pay attention to the following points: 1, the number of control parameters of the water-cooled screw chillers refrigeration coefficient of performance, rated cooling capacity, input power and refrigerant type of optional water-cooled screw chillers. 2, water-cooled screw chiller should be chosen according to the cooling load and use to consider. Each energy-saving, easy to adjust for a longer time of low-load running condition of the refrigeration system, should use multi-head piston compressor group or screw compressor group. 3, when the selection of a water-cooled screw chillers priority units with higher performance coefficient values; According to the statistics, most chillers throughout the year at 100% load running time of about 1/4 of the total running time. Total running time of 100%, 75%, 50%, 20% load running time ratio caused by 2.3%, 41.5%, 46%, 10.1%. So, in the selection of chillers priority flat efficiency curve models. At the same time, to be considered in the selection of the design load adjustment range of water chillers. Multi-head screw chillers part load performance can be chosen according to the actual situation. Optional water-cooled screw chillers, pay attention to the conditions of the nominal conditions; actual cooling capacity of the chiller with the following factors: cold water water temperature and flow; cooling water inlet temperature, flow rate, and fouling factor. Optional water-cooled screw chillers, pay attention to the normal operating range of the unit models, the main current of the main motor current limit is the current value of the nominal operating conditions shaft power. The flow of nominal operating conditions, the cold water outlet temperature should not exceed 15 degrees Celsius, the outdoor dry bulb temperature of the air-cooled unit does not exceed 43 degrees Celsius. To exceed the above-mentioned range, to understand whether to allow the use of the compressor with the adequacy of the power of the main motor. This machine free one-year warranty. Year warranty period, the company may apply to the customer's plant at any accredited professional technicians to conduct inspections and the use of equipment to guide the purchase of equipment to the customer. After the end of the warranty period, the company professional services staff will regularly visit the customer's plant, in order to amend the discovery of the problem, make a written report to the client management department. Customer reaction, the company will give a reply within 2:00 and professional and technical personnel dispatched within 4 hours for processing. The company has a sufficient inventory of spare parts, ready to meet the needs of customers. The promise: all customers to buy the machine, chiller, mold temperature of the Company mixing machine, dryer, mill and other equipment are entitled to the the lifelong best price to buy the rights of all spare parts for maintenance.
