Capacity Control

Custom-engineered capacity controllers offer increased operating flexibility for improved efficiency and lower energy consumption. Cook Valve provides a full line of plug unloaders, finger unloaders and clearance pockets, in a variety of configurations. Most compressors can be retrofitted in the field, and manual unloaders can be converted to pneumatic actuation.

A Cost-Effective Option
Whether the need is to upgrade or automate an existing compressor,
provide a viable alternative to recylindering, or allow operation over
a wider range of conditions, a custom-engineered capacity control
system can achieve optimum results without the need for a sizable
investment in new equipment.

Advantages
• Improve overall compression efficiency
• Vary capacity needs in stages
• Reduce energy consumption and help prolong driver life by
eliminating compression ("loading") during start-up
• Reduce unloaded horsepower
