于1918年，作為機床，空氣壓縮機，液體泵及汽車發動機修理，多蘭在1932年開始建設壓縮機及制冷系統。多蘭產生了自1957年以來，今天半封閉壓縮機他們是公司的核心業務的制造商。 Today Dorin are able to offer a vast range of over 70 semi-hermetic compressors ranging from 0.4 HP to 150 HP for both HFC and HCFC s to better meet the requirements of the market.今天，多蘭能夠提供超過70個半從0.4到150馬力惠普為HFC和HCFC封閉壓縮機等廣闊的s到更好地滿足市場的要求。 To these are added a series of 2 stage compressors and a full range of accessories. Efficiency, reliability and robustness are the principle characteristics of our compressors which are ready to face the stringent challenges and requirements of the new millennium. Quality, Quality and Quality: this is Dorins' commitment.除此之外，它們還為2級壓縮機和全系列的配件系列。效率，可靠性和穩健性是我們的壓縮機的主要特點是準備面對嚴格的挑戰和新的千年的要求。質量，質量和質量：這是Dorins的承諾。 Quality of suppliers.優質的供應商。 Quality of components: each single component is subjected to rigorous testing to ensure compliance with strict specifications. Quality of Production: each production phase and each compressor is continuously monitored and tested to rigorous standards.質量部分組成：每一個組成部分是經過了嚴格的測試，以確保遵守嚴格的規范。生產質量：每一個生產階段，每個壓縮機不斷監測和檢驗，嚴格的標準。 The resulting data is archived and available at our clients disposal. The various phases are followed and controlled in accordance with the Quality System ISO9001-2000 certified by Lloyds Register Quality Assurance (Certificate No. LRC 170322).
