HydroCOM – Stepless Capacity Control System
HydroCOM is a stepless and fully automated capacity control system for reciprocating compressors. Often a reciprocating compressor delivers more gas than required by the process. This causes due to the physics and design of the compressor as well as the fluctuations in the process. The operating principle of the HydroCOM is based on the reverse flow principle. This means that only the gas flow that is needed for the process is compressed. This avoids the reuse of process gas and the cost of electrical energy for the driver can be significantly reduced, thus increasing the profitability of your plant.
When efficient part load is required, the HydroCOM system allows a simpler compressor design, with significantly fewer cylinders, compared to on/ off control. In addition, individual adaptation, to your needs, of the hydraulic unit is possible.
How does the HydroCOM system work?
Around 1,600 systems are currently in reliable operation. The hydraulic HydroCOM actuators enable fast and precise control without any loss of performance, if required even from 10* to 100 percent within three revs. The wide, stepless volume control range thus ensures optimum process control. Thanks to the interface to PLC or process controller, the HydroCOM allows fully automated control. Reliable and standardized components drastically minimize the risk of unplanned downtime.
* depends on application
Due to its modular design HydroCOM is easy to integrate into both existing and new compressor installations. Process control tasks are implemented ideally in a PLC or a loop controller. In a control cabinet the HydroCOM “Compressor Interface Unit” (CIU) carries out data exchange between PLC and HydroCOM actuators. Embedded temperature monitoring of suction valve covers allows insight into compressor conditions such as leaking valves.

Benefits at a glance
Reverse flow principle
E. g. on/off controller, gap pockets and variable speed controls either allow only certain stages (25, 50, 75, 100 %), limit the control range or reduce the flexibility and speed for volume changes. Thanks to the reverse flow principle, HydroCOM compresses exactly the amount of needed gas for the process.
Stepless control, independent of the number of compression chambers
Your compressor has a smaller size
Soft-touch damper
Reduced stress on valve sealing elements and ensure long service life of suction valves.
Modular design
Complete and easy integration into the control system, as well as easy upgrade and integration of existing compressors.
Integrated temperature monitoring of the suction valve covers
Continuous condition monitoring of the compressor or valves
