eHydroCOM
Electric Stepless Capacity Control

Solve stepless control tasks now – in seconds

HOERBIGER’s eHydroCOM is the most powerful and compact all-electric stepless capacity control system available for reciprocating compressors. It’s the ideal way to achieve stable control of dynamic processes. Many 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 recycle gas is wasted. eHydroCOM, on the other hand, 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 control at the same time.

eHydroCOM – “one size fits all” means simplicity

Easy installation and integration characterize eHydroCOM, along with fast product replacement. High energy losses and long downtimes become things of the past. Spares are simple to stock and quick to install. In the rare event of a breakdown, you can quickly resume normal operation, minimizing both energy costs and emissions.

All the benefits of dynamic capacity control

eHydroCOM provides a wide control range: stepless turndown from 10–100% facilitates rapid, automatic capacity großen changes. Thanks to theDank wide control range and the ability to run your compressors more flexibly, you can meet demand with a smaller fleet and avoid overcapacity.

A low-maintenance solution

The patented eHydroCOM actuator is an intelligent device combining various electric drive technologies. Thanks to its electromagnetic operating principle, the system runs almost wear-free. The resulting long service life increases the efficiency of your compressors and supports sustainable production by reducing waste.

BENEFITS AT A GLANCE

FEATURE Reverse flow control: The delivery rate of the compressor adjusts continuously to the requirements of the process
ADVANTAGE No need for energy-wasting bypass valves
YOUR BENEFIT Saves energy and CO2 emission costs, while improving process control
FEATURE Remote support
ADVANTAGE Faster service and lower travel costs
YOUR BENEFIT Minimizes energy use and cuts air pollution
FEATURE Reverse flow control: wide control range, and ability to assign new duties to individual compressors
ADVANTAGE Flexibility in the compressor fleet and fast response to changes
YOUR BENEFIT Smaller fleet footprint, increased versatility, and no overcapacity
FEATURE Standardized system: “one size fits all”
ADVANTAGE Easy device exchange and use of existing spare parts
YOUR BENEFIT Minimal energy losses and emissions, because you can quickly resume normal operation
FEATURE Electromagnetic operating principle
ADVANTAGE Low maintenance
YOUR BENEFIT Lower lifetime costs, sustainable production over a long service life, and less waste
With eHydroCOM, our employees – even those without years of operating experience – are able to start and stop the compressors. Thanks to the significantly more robust controls, pressure fluctuations in the hydrogen systems are almost imperceptible, and so we avoid unplanned downtime. The support through remote maintenance works perfectly.
