TRFLEX® ECO Flexible storage berm for moderate mechanical constraints

Description

How can you create a simple, quick, and effective temporary storage area for short to medium periods for your oil-filled power transformers?  SANERGRID’s TRFLEX-ECO range is the answer to this problem, thanks to the design of its flexible bunds and their very high technical specifications, which can withstand lorries, cranes, rip-rails and other mechanical stresses associated with handling power transformers.

The TRFLEX ECO range is made up of 3 distinctive elements:

Extensive feedback on TRFLEX technology

SANERGRID’s TRFLEX ECO flexible tarpaulin for transformer storage is the direct result of extensive experience in dealing with oil spills and managing hydrocarbon pollution on the high seas. SANERGRID has redesigned this ultra-strong tarpaulin, which is mechanically and chemically resistant and treated against ultraviolet rays, to adapt perfectly to the constraints associated with the storage of electrical transformers.

• Reinforced PVC tarpaulin with double internal weft in high-tenacity 1670 DTEX polyester for improved mechanical resistance to tearing, perforation, cutting and tearing.
• Tarpaulin covered with a double-sided vinyl (PVC) resistant to hydrocarbons and ultraviolet rays with a total weight of over 800 g/m² for enhanced resistance to abrasion, sunlight, and hydrocarbons.
• Unlike traditional tarpaulins on the market, the double-sided induction process provides double retention security: in the event of a non-through cut on one side, the opposite wall continues to act as retention.
• All our welds are made using a unique double-sided ultrasonic welding process, which makes the welds extremely robust and guarantees that the TRFLEX flexible containers^® are completely watertight.

Structure to hold the tarpaulin in place with brackets 100 mm to 500 mm high

• TRFLEX ECO+ tarpaulin sleeves are welded all around the trough in our factories. These sleeves are used to hold the feet that support the vertical walls. For the TRFLEX ECO+ range, this angled metal structure is made of hot-dip galvanized steel as standard. Aluminium or stainless steel can be supplied on request.
• All our TRFLEX range of retaining structures have been sized and tested by our factory to maintain their retention integrity up to 120% of their communicated nominal volume.

Protection against abrasion, puncturing and cuts

The TRFLEX ECO, ECO+ and REFOR ranges are supplied with 2 layers of GEOGRID™ protective geotextile, a special anti-abrasion material made of polypropylene reinforced with polyester.

• One covering 110% of the surface of the planter, to be placed under the planter to protect it from uneven ground and, above all, to make it easier to fit the tarpaulin without slipping.
• The other 50% of the surface of the tray to be placed in the tray, to protect against scratching and punching when the equipment is installed.
• Finally, for simple on-site repairs, all our TRFLEX^® ECO, ECO+, MAINTENANCE, ECOTRUCK™ and REFOR tanks come with a tarpaulin repair kit with patch and glue in the event of punctures or tears of less than 10 cm.

Please note: all our low rainwater drainage points are between 30 and 50 mm from the ground by default. It is normal to have a residual level of water in the tanks. We recommend raising your water-sensitive equipment several centimeters above ground level using planks, wooden wedges, or concrete joists. For specific low point requirements, please contact us.
