Mehrer diaphragm compressors SERIES MRE, MHx, MLx Mehrer diaphragm compressors are available in single- and twostage design, air- or water-cooled and designed for final pressure up to 1000 bar. These compressors are used especially when absolutely oil- and leakage-free compression of toxic and flammable gases is required. Depending on the specific application, a vertical, horizontal or L-design is applied. Mehrer diaphragm compressors can be run with pre-pressure. Mehrer diaphragm compressors are used primarily in the following sectors: · Food & Beverages · Chemistry · Petrochemistry · Machine Construction · Raw Materials · Environment · Special Engineering The most important advantages: 100% oil-free compression without the use of filters Leakage < 10-5 mbar l/s Suitable for all gases Low noise level Durable Efficient Robust Risk assessment according to DIN EN ISO 1
