Since nearly three decades HydroCOM is the world-standard when it comes to stepless compressor capacity control. It does so by utilizing the reverse flow concept. The idea is simple. HydroCOM is delaying the start of compression inside the cylinder by actively keeping the suction valves open for a precisely controlled amount of time, until the desired capacity is reached – fully automatic, with every revolution of the compressor. Gas that is not required and does not need to be compressed can simply flow back to the suction side - hence the name reverse flow control. The required unloading force is generated by oil pressure. A solenoid valve is used for control. HydroCOM eliminates the need for energy-wasting bypass valves, saves energy while at the same time improving process control, and reduces the compressors OPEX and CO2 emissions.

With the market launch of the fully electric eHydroCOM systems a cutting edge, completely oil-free solution for reverse flow control became available. The unloading force to keep the suction valve open is generated by means of an electromagnet. This system architecture renders hydraulics obsolete and allows highest standardization, thus simplifying installation, maintenance, repair, and asset management. With eHydroCOM compressor capacity control is easier than ever before. Two distinct system versions with different application limits are available.

eHydroCOM HD – Heavy Duty Single Stack Actuator

A system design to perform under heavy duties. This version offers best in class payback time and total cost of ownership, while being suitable for most applications.

Reliable cylinder lubrication is one of the most sensitive issues for the operation of highly sophisticated reciprocating compressors. The wrong dosage can cause damage through wear or over-lubrication. This means: unscheduled downtime, costly production losses or consequential damage in other parts of the production. Time to delegate this important task. The XperLUBE system is designed to increase the performance and cost efficiency of your compressors. It does so by utilizing the common-rail concept, where each lubrication point is equipped with an individual injector, consisting of a solenoid valve for oil flow control and a sensor for oil flow monitoring. XperLUBE supplies your compressor with exactly the right amount of lubricant. Always. Under all conditions.
