eVCP – Electric Variable Clearance Pocket
Safely optimize compressor efficiency when field conditions change
Our eVCPs have demonstrated a 10 percent increase in capacity through the better utilization of our compressors’ horsepower.
„What is eVCP?
The HOERBIGER Electric Variable Volume Clearance Pocket (or eVCP) is an automated, stepless, variable clearance pocket system that helps better maximize capacity from your compressors. Incorporating eVCP into your compressor setup moves your output to the maximum.
How does eVCP work?
By allowing a user to steplessly adjust a reciprocating compressor’s capacity in real time, eVCP enables you to precisely control the load and maximum throughput, even under fluctuating field pressures and conditions.
As shown in this diagram, eVCP eliminates the gaps between the “actual” load on the machine and the maximum “possible” load compared to stepwise control methods. With eVCP, control is fully automatic due to the system interfacing with the compressor’s control system.
What are the benefits of using eVCP?
With eVCP, you can capture the additional capacity that stepped systems leave behind, with some customers reporting an additional 10% capacity gain. The result: No more manual adjustments, and no more lost output. Additional benefits of eVCP are highlighted below.
| Feature | Advantage | Benefit |
|---|---|---|
Produce and sell more gas | Increase production efficiencies in fluctuating suction pressure applications |
Automated stepless control |
| Reduce lost production opportunity | ||
| Gain operational flexibility and increase utilization | ||
Improve safety on site | Compressor is auto set to safe operating range, minimizing wear and unscheduled breakdowns | |
| No need to manually stop machines to safely adjust pockets; reduce unplanned manual compressor work | ||
| Lower emissions and comply with stricter standards | Engines operate at full capacity and run cleaner with less emissions |

Maximize capacity with a rugged design, automatic control and easy maintenance
eVCP’s robust design and safety automation ensures more precise load control and prevents improper adjustments. This system is also easy to maintain in the field - it uses standard components and requires minimal maintenance onsite.
| Key Benefit | Key Advantage |
Economics applications, you gain additional throughput. The system also helps your compressors run more safely, decreasing the risk of unscheduled shutdowns and further increasing your machines’ reliability. This also saves money due to less wear and maintenance, and a decreased need for spare parts. All of this is made possible thanks to eVCP’s automated stepless control. | Increase throughput thanks to the increase in utilization and operational flexibility |
| Compliance Increase production sustainability and avoid compliance and environmental regulations issues. With this increase in operational flexibility and utilization, you’re able to produce more with the same or less effort. eVCP also can help your engines run cleaner, thus increasing compliance with stricter emissions laws and standards. | Run your engines cleaner and produce less emissions |
