Double-Wall Tank with Vacuum Safety Monitoring (VSM)

Double-wall tanks made of PE-HD with wound cylinder jacket (wound pipe), vacuum leakage monitor and building authority approval Z-40.21-169. All double-wall tanks are planned, manufactured and equipped according to your individual specifications (Equipment – double-wall tank).

formoplast double-wall HDPE tanks are the safe and environment-friendly solution for storage of hazardous substances (List of media). Their double-wall design with integrated VSM leak monitoring eliminates the need for secondary containment systems.

The annular void space between the walls is constantly monitored by a certified leak detection device. The pressure in the void space is maintained within narrow limits by a vacuum pump. An increase in pressure above the upper limit is an indication of a leak which immediately triggers a visual and acoustic alarm. The acoustic alarm can be turned off only by resetting a sealed switch. The flashing light alarm stays on until the damage has been located.

Our flat-bottom tanks are available with optional walk-on working platforms and cage ladders for easy access and inspection. formoplast tanks can be supplied with electric-jacket heaters or over-the-side immersion heaters for controlled-temperature storage and/or energy-saving Polyurethan foam insulation.
