ROOTs Steam Compressor

MVR is the abbreviation of mechanical vapor recompression technology. Shangu ZQRSR series products are steam compressors specially developed by our company for MVR system. High temperature steam corrosion and leakage are two main problems in the use of steam compressor. Based on our accumulated experience for many years, we have summarized the solution of 2205 stainless steel+mechanical seal. SS2205 has better chemical and mechanical performance than SS304 or 316. Mechanical sealing can 100% prevent  the leakage of steam from the shaft.

We currently produce 9 sizes of Roots Steam Compressor.
