Windlass Modular Frac Accumulator System

Windlass Modular Frac Accumulator System

Efficient and Reliable Frac Valve Actuation Solution

Our Modular Frac Accumulator System offers a highly efficient solution for frac valve actuation that surpasses traditional HPU systems. This field-proven system significantly reduces the Total Cost of Ownership, providing a superior and streamlined product. Known as the CHPU/POD system, it features a single central power unit (CHPU) that powers each individual Remote-Control Panel (POD), substantially lowering the carbon footprint.
