Double Folding Frame Water Tanks
Maximum Water Capacity. Minimal Storage Space.
Husky® Double Folding Frame Portable Water Tanks are designed for departments and organizations that need high-capacity portable water storage without sacrificing valuable storage space. Featuring an innovative double-fold frame design, these tanks fold twice—reducing the overall storage length by approximately half compared to traditional folding frame tanks.
Whether you're supporting rural firefighting operations, water shuttle operations, emergency response, or temporary water storage, Husky® Double Folding Frame Tanks provide the durability, portability, and space-saving convenience today's crews demand.
Unique Double-Fold Design for Easier Storage
Unlike standard folding frame tanks, Husky® Double Folding Frame Tanks incorporate a second folding point on the long side of the frame. Heavy-duty laser-cut hinges and secured locking pins allow the frame to fold again after standard collapse, creating a significantly smaller storage footprint.
This design is ideal for:
- Fire departments with limited apparatus storage space
- Tankers carrying multiple portable tanks
- Municipal emergency response teams
- Rural and volunteer fire departments
- Mobile water supply operations
- Industrial and environmental containment applications
Fast Deployment. Faster Tear-Down.
When every minute counts, Husky's proven folding frame tank design allows for rapid setup and easy operation in the field. The double-fold feature affects storage only—deployment remains quick and straightforward.
Every Husky® Double Folding Frame Tank includes:
- Patented Easy Lift Handles® (US Patent No. 8,746,478 and US Patent 10,518,967)
- Quick-Release Drain Tube
- Replaceable liner system
- Heavy-duty folding frame construction
- Secure pin-retention system
- No complicated assembly required
These features help crews reduce setup time, improve safety, and simplify tank tear-down after operations are complete.
Built for Long-Term Durability
Every Husky® Double Folding Frame Tank is engineered for years of dependable service in demanding environments. Heavy-duty MIG-welded frames, laser-cut hinges, reinforced construction, and premium liner materials help ensure reliable performance under repeated use.
Husky® was the first company in the firefighting portable tank industry to offer a lifetime warranty on welds and welded seams, providing added confidence and long-term value for departments and organizations investing in portable water storage equipment.
