Performance & Safety
in liquid and gas storage, since 1957

LARCO designs custom automation systems to optimize and secure operations at oil depots. Using programmable logic controllers (PLCs), HMI interfaces, and supervision solutions, we deliver a comprehensive and fully tailored response to the site's specific requirements and operational constraints. Our expertise covers both safety automation and process control, with remote access capabilities via a connected gateway.

This automation cabinet is designed to manage up to 10 LARCO overfill prevention or leak detection devices. It is fully configurable via a 12.1-inch HMI, allowing intuitive and efficient setup. All configurations can be performed by LARCO’s local partners.

The cabinet also includes a secure remote access gateway, featuring a unique encrypted certificate and a physical authorization key. This enables fast remote support and software updates while ensuring maximum cybersecurity.

The DOCIL C 500 BTFO probe is designed for pressurized tanks such as LPG spheres or liquefied gas storage tanks. It triggers an alarm as soon as a preset level threshold is reached, preventing overfilling and overpressure.

The breather valve is a safety device designed to regulate the pressure inside hydrocarbon storage tanks. It compensates for pressure variations caused by product movement or temperature changes, while ensuring a perfect seal during normal operation.

The strip level gauge is a simple and reliable mechanical gauging system with an accuracy of ±25 mm. It provides instant visual indication of the product level in a tank. Operating without electricity, it offers direct on-site reading, even in the absence of a control room.

The DOCIL C400 is an overfill protection probe for liquid hydrocarbons. It is equipped with an optical sensor that, when immersed in the product, triggers an alarm.

• Enhances storage and depot safety
• 3 adjustable detection levels
• ATEX & SIL2 / SIL3 certified

The COVERFLOTE® is an internal floating cover designed for installation inside fixed-roof tanks storing liquids that may evaporate or oxidize upon contact with air. Made of self-floating panels, the COVERFLOTE® remains in constant contact with the liquid surface, eliminating the formation of any vapor phase between the panels and the product.

Its peripheral seals adapt to irregularities in the tank wall, ensuring a tight fit. This design reduces product evaporation by up to 98%, significantly lowering VOC emissions while enhancing both site safety and financial performance.

The floating suction system is a withdrawal mechanism designed to extract only the upper layer of liquid stored in a tank. Supported by a float, it remains at the surface and draws the purest part of the product, avoiding any sediments or particles that may settle at the bottom of the tank.

The RGA750 grounding reel is an essential safety device for floating roof tanks. It ensures a low-impedance connection between the floating roof and the tank shell, drastically reducing the risk of electrical arcing and fire in the event of a lightning strike.

The DOCIL C 510 is a high-pressure level probe designed for pressurized tanks, particularly LPG tank trucks and railcars. Equipped with two integrated optical sensors, it secures filling operations by automatically triggering pump slowdown or shutdown before any overfill occurs, while preserving the gas phase. This enables operators to maximize usable tank volume without compromising loading safety.

The DOCIL HK hydrocarbon detector instantly detects the presence of liquid hydrocarbons, even in the presence of water. It provides reliable monitoring of sensitive areas such as containment basins, decanters, or pumping stations, and triggers an alarm in the event of hydrocarbon detection.

The gauge pad is a mechanical device installed on the gauge rod vertical, providing quick, secure, and direct access to the product stored in a tank. It facilitates manual gauging by ensuring a reliable entry point compliant with French regulations.

In a sector where efficiency, safety, and compliance are paramount, SETMAT provides a comprehensive response to the challenges faced by depots. Our advanced ERP, DPPACK, along with our intelligent loading bay equipment, optimizes stock management, loading operations, and logistical flows, while ensuring flawless traceability.

The TOO and TOR hydrocarbon separation valves are designed to automatically separate water from hydrocarbons in tanks, preventing any product spill onto the ground.

The JTC (Compression Plate Gasket) is a sealing solution designed for fixed-roof tanks with internal floating covers and for external floating roof tanks. Thanks to its robust materials and custom-made design, the JTC provides a reliable and durable way to reduce evaporation, protect the environment, and improve site safety.
