Professional window cleaners and building-maintenance crews running an Unger HydroPower Ultra pure-water pole system depend on a fresh supply of deionizing resin to keep every rinse spot-free. This small-tank replacement resin canister restores full DI capacity to a HydroPower Ultra single-stage vessel in seconds, so a tech can swap spent resin between stops instead of stopping mid-route to babysit water quality.
Built for
- Professional window cleaning crews running waterfed pole systems on daily routes
- Facility maintenance teams cleaning storefront glass, skylights, and low-rise exteriors
- Solar panel cleaning contractors who need a spot-free final rinse
- Mobile detailing and pressure washing crews carrying a HydroPower Ultra cart
Specifications
Unger's FloWater Technology distributes water evenly through the resin bed, delivering up to 30% more pure water per fill than older canister designs. A single bag typically runs 10-14 hours of continuous use, though harder starting tap water shortens that window. The color-coded KeyLock system and FastLock canister lid make swapping resin a tool-free, 30-second job, and the sealed design includes a pressure-release valve for safe opening. Output is commercial-grade zero-TDS (total dissolved solids) pure water suitable for spot-free glass and solar panel rinsing.
Frequently asked questions
How long does one resin bag last?
Typically 10-14 hours of continuous use. Water hardness is the biggest variable - crews working in areas with higher incoming TDS report needing to change resin more often, so it's worth testing your source water and budgeting resin per route accordingly.
Will this resin still work if my tap water has high TDS?
DI resin removes dissolved solids from the water, but very high incoming TDS shortens resin life dramatically. If your local water tests high, plan on carrying spare canisters or consider a pre-filter stage ahead of the resin vessel.
How do I know when it's time to replace the resin?
Check output water with a TDS meter. Once the reading starts climbing off zero, the resin bed is exhausted and it's time to swap in a fresh canister to avoid spotting on the glass.
Does this fit any HydroPower Ultra system?
This canister is sized for the HydroPower Ultra single-stage (small tank) vessel. Multi-stage HydroPower Ultra carts use additional resin stages sold separately.
