New H Range State-of-the-art 达到最高工艺水平的 新H系列,Thanks to the new valve plates, to
2、 the new internal passages design, and to the new bearings also the H compressors are showing very low Noise levels compared with the K models. (But compared with the other compressor brands in the market also!)Comparison tests had showed noise levels reduction up to 13 db(A).新型的阀板， 内通道的改进， 新的轴承的使用，
3、 H系列与K系列比较， 噪声明显降低（与市场上其它品牌压縮机相比也要低）比较性试验表明噪声值要低13分贝。,5,Improved Performances,5. New H Range State-of-the-art 达到最高工艺水平的 新H系列,更好的性能比较性试验证明新的H1000CS与比泽尔（德国生产的）八角机的相当的型号比较， 结果： Some comparison tests between the new H1000CS and an equivalent Bitzer model (Octagon range) showed the following results:Mass
