Process control system eHydroCOM

Solve stepless control tasks now in seconds Many reciprocating compressors need to deliver less than their rated capacity for much or all of the time. Traditionally, this requires excess compressed gas to be returned to the suction side via a recycle valve. The energy used to compress this recycled gas is wasted. HOERBIGER’s eHydroCOM is the most compact and all-electric stepless volume control system available today for reciprocating compressors. The 100 % oilfree and fully standardized system is the ideal way to achieve stable capacity control of dynamic processes. The 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. This not only saves you energy and reduces CO2 emissions, but also improves your process controls at the same time. One system – many possibilities Conventional systems, such as step or bypass controls, do not work efficiently, are often slow and can only be adjusted with great effort and not accurate to the required delivery rate. The eHydroCOM system allows you a wide control range: Stepless from (0...)10* to 100 %. Due to the reverse flow control, the delivery rate is adjusted fully automatically and, above all, continuously. Thanks to the large control range and the possibility to operate your compressors more flexibly, you can cover requirements even with a smaller fleet, react extremely quickly and avoid overcapacities. Failure prevention through real-time monitoring of the actuator eHydroCOM offers a wide range of control: stepless turn down from 10–100% allows for rapid, automatic capacity adjustments.
