Achieve precise and fast process control while saving energy
Many reciprocating compressors need to deliver less than their rated capacity, and this typically requires excess compressed gas to be returned to the suction side via a recycle valve. When this happens, the energy used to compress this recycled gas is wasted. HOERBIGER’s eHydroCOM is an all-electric stepless volume control system available today for reciprocating compressors. The fully standardized, 100% oil-free system is the ideal way to achieve and maintain stable capacity control of dynamic processes. Precise capacity control eHydroCOM continuously adjusts the compressor’s delivery rate to match the amount required by the downstream process. Precise control of the suction valves eliminates the need for a bypass valve. This not only saves energy and reduces CO2 emissions, but also improves your process controls at the same time.
