eHydroCOM – Electric Stepless Capacity Control System

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.

eHydroCOM offers a wide range of control: stepless turn down from 10–100% allows for rapid, automatic capacity adjustments. Thanks to the broad control range and the ability to run your compressors more flexibly, you can meet demand with a smaller fleet and avoid overcapacity.Digital networking allows you to monitor your actuator in real time and can thus detect failures at an early stage and avoid these in the best case. But not only that: Any problem that may arise can be can be solved with temporary access via remote maintenance. If spare parts are required, HOERBIGER always has semi-finished products ready for you – eliminating unnecessary storage costs for you.
