　　半封閉壓縮機

　　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.

　　燃氣管理和改進下一代鐵餅®閥門技術提供更好的運營效率，特別是在運行條件下的半封閉壓縮機運行最頻繁。

　　The streamlined body of 4D and 6D semi-hermetic compressors improves gas flow and oil management, and increases efficiency.在四維及6D精簡機構，半封閉壓縮機提高天然氣和石油流通管理，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.

　　改進四維及6D固體后鐵餅的家臣提高效率，降低音量由3至5分貝鐵餅從現有的模式。 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.

　　新的四維及6D半封閉壓縮機的功能改善頭部的設計，減少排放脈動水平達20多蘆葦模型的水平減少百分之聲音。 A unique crankcase ventilation system manages oil better and reduces the oil circulation rate by 80 percent.

　　獨特的曲軸箱通風系統，更好地管理石油和減少百分之八十的石油流通速度。

　　Proven Technology 成熟的技術

　　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技術的最新一代納入四維及6D提供了壓縮機的使用壽命，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.四維及6D模型兼容Sentronic ®潤滑保護系統-業界最精確和一個不需要毛細管，可以休息或泄漏，并提供了最大的壓縮機的保護以及環境的完整性。 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.

　　為了提高服務能力和易用性的轉換，改進的四維及6D具有相同的尺寸，安裝閥門腳和服務地點，并為以前的型號減少近等于能力在現有的四維及6D壓縮機更換。

　　Ease of Application 易于應用

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

　　四維及6D新型號的低聲音減少脈動，并簡化應用，降低應用成本。 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.

　　改進四維及6D壓縮機，更是為環保制冷劑的更廣泛的應用而設計，確保谷輪®半封閉壓縮機，是今天和明天的正確的技術。
