eHydroCOM – Electric Stepless Capacity Control System

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.

Standardized and ready for use immediately
The patented eHydroCOM actuator is a smart device that combines a range of electronic and electric drive technologies to increase the reliability, efficiency and lifetime of your compressor. With no hydraulic oil to leak, and a design that is almost wear-free in operation, eHydroCOM reduces potential points of failure and keeps downtime to a minimum.

Failure prevention through real-time monitoring of the actuator
Digital networking capabilities allow you to monitor your actuator in real time and thus detect failures early – or even avoid them altogether. And, thanks to our remote maintenance system, any problems that do arise can be quickly assessed by HOERBIGER experts if necessary. If spare parts are required, HOERBIGER always has semi-finished products ready, reducing or eliminating the need for you to carry spares.

Reduced operating costs with eHydroCOM  
Taking advantage of plug-and-play connections, eHydroCOM XD – our most powerful and compact system for extreme duties – can be easily retrofitted to your existing compressors with minimal downtime. The self-calibration feature means that even untrained personnel with less experience can install and commission eHydroCOM. In line with the motto “one size fits all”, it’s easy to replace the actuators. For you this means less inventory and less downtime. Your compressor is ready for use again immediately after maintenance.
