Typical Flushing Services

We mobilize quickly for emergency outages, scheduled outages, routine maintenance, and pre-commissioning of new equipment.

Typical Flushing Services Include:


High Velocity Oil Flush

Welding slag, dirt, debris, and water often contaminate the inside of the tubing and piping of critical hydraulic oil, lube oil, and fuel oil systems.  OFS utilizes state-of-the-art high flow flushing equipment to achieve “turbulent flow” and a Reynolds Number of >4000 to effectively “flush” all contamination out of the piping, meeting or exceeding stringent cleanliness specifications established by leading OEMs (including GE, Solar, Caterpillar, etc.)

Varnish Removal Flush

Hard varnish deposits often plate out on the metal surfaces of gas turbines, compressors, and other lube oil and hydraulic systems, adversely affecting the operation and performance of the equipment.  Using a specialized flush procedure and cleaning agent, hard varnish deposits can be effectively removed from the piping, reservoirs, and other metal surfaces (i.e. servo valves, pressure control valves, etc.), thereby improving the system’s performance and reliability.

Thermal Transfer Fluid Flush

Sludge, solids, and other contaminants often accumulate within the piping of Thermal Transfer Systems, adversely affecting their thermal conductivity and overall performance.  Utilizing specialized cleaning agents, flush procedures, and state-of-the-art flushing equipment, OFS can quickly clean the entire system and restore it to “like new” condition and performance.

EHC Fluid Flush

OFS manufacturers and uses specialty flushing equipment designed for use with phosphate ester and other synthetic EHC fluids (including Fyrquel®) 

Confined Space Entry Reservoir Cleaning

All of the OFS Field Service Technicians are trained and certified for Confined Space Entry, and we regularly perform internal Tank Clean-Outs on both lube oil and fuel reservoirs.  Wiping down the inside of the reservoir with lint-free rags to ensure optimal cleanliness is an important part of most stringent OEM flush procedures.

On-Site Oil Analysis

Our highly qualified and experienced Field Service Technicians analyze oil samples onsite using a Portable Fluid Analysis Kit and Laser Particle Counter to accurately determine the ISO/NAS cleanliness level and amount of water in the oil.
