21&24 Fiberglass Tanks - Twin Unit Ski
Keep your commercial water treatment running nonstop with our heavy-duty multi-tank skid system.

The challenge
Commercial facilities relying on water softening or filtration face costly downtime and equipment damage when single-tank systems regenerate or fail. Hard water scale buildup reduces heat exchanger efficiency by up to 20%, drives energy costs higher, and shortens equipment lifespans by nearly half.
Unexpected service interruptions during regeneration cycles or maintenance risk operational disruptions, compliance failures, and increased maintenance expenses. Facilities need a solution that guarantees continuous, high-volume water treatment without interruption.
How it works — the technology
The 21" & 24" Fiberglass Tanks Twin Unit Ski is a pre-engineered commercial skid designed to mount multiple fiberglass treatment tanks in a coordinated multi-tank layout. Fiberglass-reinforced tanks resist corrosion and pair seamlessly with high-flow control valves to deliver reliable softening or filtration.
By operating tanks in tandem, this skid enables continuous service: while one tank regenerates or backwashes, the other maintains full flow, ensuring uninterrupted delivery of treated water at commercial scale. The robust ~290 lb engineered skid structure supports heavy charged tanks and plumbing, providing a clean, organized installation footprint and easy service access.
Capacity & what it handles
- hard water scale and minerals
- corrosive elements damaging plumbing
- sediment and particulates (with filtration media)
- water contaminants that reduce equipment life

Frequently asked questions
Why choose fiberglass tanks?
Fiberglass tanks resist corrosion better than steel, ensuring longer service life and compatibility with high-flow commercial valves.
How does the multi-tank skid prevent downtime?
While one tank regenerates or backwashes, the other(s) continue treating water, maintaining continuous flow and preventing service interruptions.
Can this skid support both 21" and 24" tanks?
Yes, the skid is engineered to securely mount and support either 21" or 24" fiberglass treatment tanks.
What maintenance benefits does this system provide?
The organized skid layout and coordinated plumbing simplify service access, reducing maintenance time and associated costs.
Is this system suitable for high-volume commercial applications?
Absolutely. Its multi-tank design and robust construction are ideal for continuous high-flow softening or filtration in demanding commercial environments.
