半封闭压缩机

　　Improved Efficiency 提高效率

　　Improved gas management and next generation Discus ® valve technology provide improved operating efficiency, particularly at operating conditions where the semi-hermetic compressor runs most often.

　　燃气管理和改进下一代铁饼®阀门技术提供更好的运营效率，特别是在运行条件下的半封闭压缩机运行最频繁。

　　The streamlined body of 4D and 6D semi-hermetic compressors improves gas flow and oil management, and increases efficiency.在四维及6D精简机构，半封闭压缩机提高天然气和石油流通管理，提高了效率。

　　Improved 4D and 6D solid post Discus retainers increase efficiency and lower sound levels by 3 to 5 dBA from those of existing Discus models.

　　改进四维及6D固体后铁饼的家臣提高效率，降低音量由3至5分贝铁饼从现有的模式。 The new 4D and 6D semi-hermetic compressors feature improved head designs that lower sound levels by reducing discharge pulsation levels up to 20 percent over reed models.

　　新的四维及6D半封闭压缩机的功能改善头部的设计，减少排放脉动水平达20多芦苇模型的水平减少百分之声音。 A unique crankcase ventilation system manages oil better and reduces the oil circulation rate by 80 percent.

　　独特的曲轴箱通风系统，更好地管理石油和减少百分之八十的石油流通速度。

　　Proven Technology 成熟的技术

　　The latest generation of 3D technology is incorporated into the 4D and 6D to provide even greater reliability over the operating life of the compressor.

　　3D技术的最新一代纳入四维及6D提供了压缩机的使用寿命，甚至更高的可靠性。 4D and 6D models are compatible with the Sentronic ® lubrication protection system - The industry's most accurate and one that requires no capillary tubes that can break or leak, and offers maximum compressor protection as well as environmental integrity.四维及6D模型兼容Sentronic ®润滑保护系统-业界最精确和一个不需要毛细管，可以休息或泄漏，并提供了最大的压缩机的保护以及环境的完整性。 To improve serviceability and ease of conversion, the improved 4D and 6D have the same footprint, mounting feet and service valve locations, and near equal capacities to previous models for drop-in replacement of existing 4D and 6D compressors.

　　为了提高服务能力和易用性的转换，改进的四维及6D具有相同的尺寸，安装阀门脚和服务地点，并为以前的型号减少近等于能力在现有的四维及6D压缩机更换。

　　Ease of Application 易于应用

　　New 4D and 6D models are designed for lower sound, reduced pulsation and simplified application to lower the applied cost.

　　四维及6D新型号的低声音减少脉动，并简化应用，降低应用成本。 The improved 4D and 6D compressors are also designed for the broader application of environmentally acceptable refrigerants, ensuring that Copeland ® semi-hermetic compressors are the right technology for today and tomorrow.

　　改进四维及6D压缩机，更是为环保制冷剂的更广泛的应用而设计，确保谷轮®半封闭压缩机，是今天和明天的正确的技术。
