The photo shows the insulated bottom of the oversized shipment as it heads to Guelph, Ontario, Canada. On installation, it is set on its base with the 21 ft high x 17 ft wide opening on one end that slides horizontally sideways to allow the product to be rolled in. The door closes and is quietly locked in place by pivoting fingers activated through coil springs and deactivated by air hose expansion all in absoluted quietness. This box is designed for full vacuum to eliminate all moisture from product then hydrostatic pressure as the chamber is filled with saturating liquid which is later drained. This project represents another successful custom engineering and fabricating operation where All-Weld thinks outside the box.
