HydroCOM - Stepless Capacity Control System

WHAT IS HYDROCOM?

HydroCOM is a stepless and fully automatic volume control system that efficiently match the output of your reciprocating compressor to your process demand.

HOW DOES HYDROCOM WORK?

HydroCOM actuators provide fast and precise control without loss of capacity, from (0…)10*…100%.  This wide range of stepless control ensures optimum process control. In addition, load changes are possible within only 3 crankshaft revolutions. Thanks to the interface to DCS or process control, HydroCOM enables fully automatic control.

Modular system design

Due to its modular design HydroCOM is easy to integrate into both existing and new compressor installations. Process control tasks are implemented in a DCS or a loop controller. In a control panel the HydroCOM “Compressor Interface Unit” (CIU) carries out data exchange between DCS and HydroCOM. Embedded temperature monitoring of suction valve covers allows insight into compressor conditions such as leaking valves.

Benefits at a glance

Reduce energy and CO2 emission costs
Feature

Thanks to this reverse-flow principle HydroCOM compresses just the exact amount of gas needed for the process and saves energy. HydroCOM thus provides higher efficiency and lower emissions.

Advantage
Reduce capital costs for efficient, multistage compressors
Feature

HydroCOM provides stepless control regardless of the number of compression chambers. For example, a three-stage compressor with on/off control and stages of 25, 50, 75 and 100% would require 6 cylinders. With HydroCOM, only 4 cylinders are required.

Advantage
Increased reliability and cost efficiency
Feature

HydroCOM's soft-touch damper reduces stress on the valve sealing elements, ensuring a long service life of the suction valves.

Advantage
Complete and easy integration into the control system and easy upgrade and integration for existing compressors
Feature

Due to its modular design, HydroCOM can be easily installed in both existing and new compressor systems. Control tasks are ideally implemented in the DCS/PLC. In the control cabinet, the Compressor Interface Unit (CIU) provides data exchange between the DCS and HydroCOM actuators.

Thanks to the integrated temperature monitoring of the suction valve cover, you are informed at all times about the condition of the compressor and the valves.
