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. 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. Benefits at a glance 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 Increase throughput thanks to the increase in utilization and operational flexibility. Advantage By optimizing production in fluctuating suction pressure 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.
