Dedicated Team

Evergreen North America has a large, dedicated division of highly trained experienced professionals who are focused exclusively on providing superior industrial tank cleaning Evergreen North America delivers a higher level of responsiveness, efficiency, safety, and environmental compliance. We provide our customers with a more robust solution to their tank cleaning needs.

Cleaning Technology

Evergreen North America offers the latest, most advanced non-entry cleaning technology to protect personnel, control emissions, and increase productivity. Included are automated processes and robotic systems that operate while the tank remains sealed. These devices spray diesel fuel or any other readily available diluent to wash interior surfaces and liquefy sludge for removal. Liquefied material can be heated to improve processing efficiency and productivity.


Our robotic systems include manway canons, drop leg nozzles and robotic crawlers, as well as valve-controlled shell lances. We can gain a access to a tank through any available roof or side manway. Evergreen North America's automated cleaning devices are controlled by specialists in on-site command centers located a safe distance from the tank.

Our proven experience and success using the most advanced devices and techniques available allow Evergreen North America to engineer and customize procedures for each project in order to save time, improve productivity, and meet unique customer requirements.



Tank Sweep Nozzles

Evergreen North America's robust capabilities and specialized industrial tank cleaning equipment fleet includes Tank Sweeps. These devices were designed for the de-sludging of storage tanks by the control and circulation of high-velocity liquid streams through nozzles fitted to the tank shell via manways or other openings. Tank Sweeps are capable of volumes up to 2,500 GPM at 150 PSI. The nozzles can be utilized below the fluid line to aid in the movement of solids in the tank.

Tank Sweeps were designed to provide a safer environment for the operator, with numerous advantages:

  · Eliminating the handling of equipment on floating roofs
  · Eliminating the cutting of holes in a tank roof
  · Eliminating the use of nitrogen purge


Waste Processing & Minimization

Depending on customer requirements, material from a tank is often processed on-site to minimize waste and reduce disposal costs. Evergreen North America offers a variety of processing techniques. Belt presses and filter presses are used to dewater aqueous sludge, while high -volume decanter centrifuges are employed for oily sludge.

Evergreen's high-speed centrifuges generate a force 2,000 times greater than gravity to separate solids and liquids to produce dry waste for disposal and clarified effluent ready for potential reuse. Evergreen North America's tank specialists have a greater level of expertise that yields exceptional results-keeping a customer's waste management, transportation, and disposal costs to a minimum.

Safety & The Environment

The hazardous nature of storage tank cleaning demands the most stringent standards for safety. For Evergreen North America, safety begins with pre-project planning that includes hazard mitigation and continues with AP1-certified tank entry supervisors, rigorous daily Job Safety Analysis requirements, and more. Crew members are trained according to the highest industry standards, including 40-hour HAZWOPER and OSHA training.


Evergreen North America has an award-winning safety record

It includes the NPRA Contractor Merit Awards, Industrial Safety Training Council Safety Awards, and OSHA Voluntary Protection Programs (VPP) Star status.

Evergreen North America also keeps environmental protection at the forefront of operations. Containment procedures and strict jobsite housekeeping prevent accidental spills. Effective material processing not only reduces waste but also makes liquid components available for reuse by the plant. Vapor-tight tank cleaning controls emissions, while all degassing and vapor recovery services meet or exceed local, state, and federal regulations.
