Double Wall HDPE Tanks

Double Wall HDPE Tanks are the safe and environment-friendly solution for storage of hazardous substances. Their double wall design with integrated VSM leak monitoring eliminates the need for costly 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.
