Mehrer Compressors will introduce a new line of diaphragm compressor packages to complement its existing reciprocating compressor offerings. The diaphragm compressors will be complete, pre-assembled units capable of delivering gas at pressures up to 14,500 psi. Mehrer has engineered the diaphragm compressor packages in vertical, Vee, and horizontal configurations to flexibly match different process and plant needs. The new diaphragm compressors are designed for applications requiring small gas volumes to be compressed without contamination at very high pressures, such as in recycling processes involving toxic gases.

M ehrer Compressors will in- troduce a line of diaphragm compressor packages in par- allel with its reciprocating compressor offerings. The diaphragm compres- sors will be a plug-and-play, complete, high-pressure compression package. This new line will officially be present- ed at ACHEMA, taking place June 15- 19, in Frankfurt, Germany. Capitalizing on its experience with reciprocating compressors, Mehrer has engineered a series of packages. These diaphragm compressors are available in the vertical, vee and hori- zontal configurations, in a modular lay- out to better match the process/plant characteristics. As with all diaphragm compressors, this type of machine is used to compress, without leakages and oil contamination, small volumes of gas at very high pressures; in this specific case, delivery pressures of 14,500 psi (1000 bar) are possible. The membrane, which separates the gas-handling part from the mechano- hydraulic part of the machine, is stain- less steel featuring triple sandwich con- struction. A pressure sensor detects possible failure of one of the membrane layers and, for safety reasons, immedi- ately trips the compressor. The diaphragm diameter is select- ed as a function of the requested vol- ume flow. The alternating movement of the diaphragm is obtained by uni- formly applying a hydraulic oil pres- sure through an oil distribution plate. An oil-compensation pump assures an ideal oil volume between piston and diaphragm. These compressors feature a very high compression ratio; depending on the process, they can perform a 15:1 compression ratio in a single stage. The recycling service of large indus- trial processes when toxic gases are involved and minimum gas leakage is the main application for the Mehrer compressor packages. They feature a modular configuration in which the compressor unit can feature a vari- able number of diaphragm heads to in- crease the volume handled and, when required, more than one compressor stage to obtain a higher than 15 com- pression ratio. These compressors are generally belt-driven by an electric mo- tor at low speeds, 100 to 330 rpm. All components come from Ger- man or selected European suppliers, completely assembled at Mehrers Balingen, Germany, headquarters, and shipped as a plug-and-play unit to mini- mize site erection time and costs. The company is certified according to DIN EN ISO 9001:2008 [1]. Mehrer Compression specializes in the supply of compressors and com- pression systems tailored to the vari- ous processes of the chemical industry. Its crosshead reciprocating compres- sor line covers the 2.9 to 335 hp (2.2 to 250 kW) power range with delivery pressures up to 1160 psi (80 bar). Along with carbon dioxide (CO2), bio- gas and hydrogen, Mehrer offers a fully integrated gas portfolio.
