特点                                                                                              

RZN系列拥有性能卓越的新一代水冷螺杆式工业冷水机组,机组有多种规格,制冷范围从113520Kcal/ h - 2838700Kcal/h(压缩机功率从8 kw到1280 kw),冻水温度范围调节为7-20℃,可根据客户要求定做各种规格的特殊机组,特殊低温更低至-45℃的冰水(温差不超过± 1℃)最高效的半封闭式压缩机,机组的心脏—进口优质螺杆压缩机,其5:6超高效螺旋转子压缩机,比一般压缩机能效高20 - 30%.行可靠效率高、维护容易、精确的容量控制、应用范围广。1、最新非对称转子齿形。2、四段或无段式容量控制系统。3、内建压差式供油润滑系统。4、低振动、低噪音。

微机准确控制温度,机组微电脑控制器采用超大萤幕点阵液晶显示,具有良好的全中文人机对话介面实现全功能自动化控制。液晶显示幕即时显示机器工作状况,精确监控组运行在最佳状态,其轻触面板密封好,防水,防尘,抗腐蚀,按键寿命长。分级与无极能量控制,用于一般的空调系统,装备有100%、75%、50%、25%分级能量控制系统。以确保机组在部分负荷时发挥最大节能效果。但如需精确控制水温,可按用户要求,所有机型均可装配无级能量控制。

运行效率高,换热器采用了高效波纹管、外加高效的螺杆式 压缩机,保证了机组的高效率运行。最可靠的保护和辅助部件。冷水机有以下部件以防止任何运转故障:压缩机保护设计时器、过电流继电器、压缩机电机温感器、防冻结温控器、视液镜、油加热器、压缩机逆相保护继电器;高、低压保护、排气高温保护、安全阀、易熔塞。

 

RZN series has the excellent performance of a new generation of water cooled screw industrial water chillers, the unit has a variety of specifications, the refrigeration range from 113520 Kcal/h - 2838700 Kcal/h (compressor power from 8 kw to 1280 kw), frozen water temperature range adjustment for 7-20 ℃, can be customized according to customer requirements of various specifications of the special machine, special type low temperature 45℃ to - lower water temperature difference (not more than +/-1℃) is the most efficient semi-hermetic compressor, the heart of the unit - import high quality screw compressor, its 5:6 super-efficient spiral rotor compressor, is a 20-30% higher than average compressor efficiency line and reliable with high efficiency, easy maintenance the capacity of the control precision, wide application range. 1. The latest asymmetric rotor tooth profile. 2. The four segments or capacity control system of no. 3. The built-in differential oil lubrication system. 4. Low vibration and low noise.

Pieces of microcomputer control temperature accurately, the microcomputer controller with large screen dot matrix LCD display, has the good whole Chinese man-machine dialogue interface to realize the full function of automation control. Liquid crystal display real-time display machine working conditions, accurate monitoring group to run in the best condition, its light touch panel sealed, waterproof, dustproof, corrosion resistant, button long service life. Classification and the infinite energy control, for the general air conditioning system, equipped with 100%, 75%, 50%, 25% energy control system. This unit to ensure the maximum energy saving effect in partial load. But if you need precise control water temperature, according to user requirements, all models are assembling stepless control energy.

Running with high efficiency, high-efficiency corrugated tube heat exchanger was adopted, and high efficient screw compressor, to ensure he efficient operation of the unit.The most reliable protection and accessories. Water chiller has the following components to prevent any operational failure:compressor set timer, over-current relay protection, temperature sensor, prevent freezing compressor motor thermostat, depending on the liquid mirror, oil heater, compressor inverse phase protection relay, high and low voltage protection, exhaust temperature protection, safety valve, soluble plug.
