Non Entry Systems Ltd (NESL) has been at the forefront of designing and manufacturing cutting-edge robotic and automated industrial cleaning systems for hazardous environments and explosive atmospheres, alongside sludge handling equipment and oil recovery plants, for nearly thirty years.

NESL specializes in the design, development, and production of ATEX-certified systems that minimize exposure to hazardous environments. Renowned for our expertise, we deliver tailored solutions that meet the specific needs of safety-conscious contractors. We collaborate closely with our customers, suppliers, and end-users to ensure compliance with local and international regulatory standards. Our advanced systems eliminate the need for human entry into dangerous confined spaces, offering safe, efficient, and cost-effective solutions for cleaning, inspection, and maintenance of bulk storage tanks, lagoons, ponds, and pipelines.
Headquartered in the United Kingdom, NESL operates from an 18,000 square-foot facility where all equipment is designed and manufactured. This facility houses offices, R&D, design, fabrication, assembly, testing, painting, and electrical workshops. NESL is ISO 9001:2015 accredited, and our products are built to perform in the toughest environments, conforming to the latest industry regulations such as ATEX, UL, and CE. Additionally, all our products are designed with both functionality and user-friendliness in mind.
To maintain the highest standards, NESL employs dedicated project managers who oversee each build. Components not manufactured in-house are sourced from trusted global suppliers who share our commitment to excellence. Every component is catalogued, with serial numbers recorded, and each system is built by a team of highly trained professionals.
The products and systems we create are the result of decades of engineering expertise, innovation, and hands-on experience with tank cleaning and related challenges. These qualities have made NESL’s equipment the trusted choice in storage facilities and refineries around the world. With a global network of agents, we are always ready to respond to customer needs, no matter the time or location
