A cyclonic wellhead desander is a high-pressure solids-separation device designed to remove sand and other solid particles from well effluent (oil, gas, and water) immediately downstream of the wellhead. It uses a centrifugal (cyclonic) separation principle: the multiphase flow enters tangentially into a specially shaped vessel, creating a high-velocity spiral motion. The resulting centrifugal forces drive the denser solid particles outward toward the vessel wall, where they lose momentum, fall into a solids collection chamber (pot), and are periodically removed.

The cleaned fluids exit through the top outlet of the unit. This 10K version is designed for high-pressure well operations up to 10,000 psi (690 bar) and is commonly used in well testing, clean-up, flowback, and production protection to prevent abrasive solids from damaging downstream equipment (chokes, separators, flowlines, valves).. DPI’s modular high pressure CyFi® Solids Management and Monitoring Systems represents a game changing step forward in the field of oilfield solid management systems (SMS).

The CyFi design ethos is to: Maximize equipment performance and performance envelopes; Maximize equipment flexibility and configurability Maximize ease of use – for rig up/down times, for configuration changes and for maintenance. Minimize equipment inventory requirements. The CyFi is as it name implies “Cyclonic Desander and Filter” combined that can be operated in various scenarios with on skid piping arrangement: Operating as a Cyclonic Desander and Filter – 100% Duty/Standby Operating as a Cyclonic Desander – 100% Duty/Standby Operating as a Sand Filter – 100% Duty/Standby
