High integration: saving 1/2 of the footprint, manpower and procurement cost;

Save more: reasonable power matching realizes the small displacement job. Just need to start one engine saving the fuel cost.

More reliable: the closed-type displacement tank avoids the acid splashing. Independent acidizing and sand blending manifolds extend the manifold service life.

More accurate: rematch the sand conveying capacity of the auger to accurately control the sand for small sand ratio operation.
