Highest-Output 4-Stage RO/DI System in the IceCap Line
The IceCap 200 GPD RO/DI System is the highest-output model in the IceCap RO/DI line, producing up to 200 gallons of purified water per day with a 1.5:1 waste-to-product ratio. It is designed for hobbyists with large systems, high water change volumes, or both, where lower-output models create a production bottleneck. Like the 150 GPD, the improved 1.5:1 waste ratio makes it significantly more water-efficient than the 75 GPD and 100 GPD models, which operate at a 3:1 ratio.
The 200 GPD uses the Dow Filmtec TW30-1812-100HP membrane, the same membrane used in the 100 GPD model, providing 96 to 98% typical salt rejection at 65 PSI. The higher daily output compared to the 150 GPD comes from this higher-capacity membrane rather than from different pressure requirements; both the 150 GPD and 200 GPD require 65 to 80 PSI and share identical 16" x 6.5" x 18" dimensions.
All other features are identical to the rest of the IceCap RO/DI line: auto shut-off valve, manual flush flow restrictor, glycerin-filled pressure gauge, and all installation fittings and tubing included. Standard 10" canisters and 1/4" push-connect fittings make replacement filter sourcing straightforward.
Key Features:
- 200 GPD output is the highest in the IceCap RO/DI line, rated for the fastest fill times and largest water change volumes.
- 1.5:1 waste-to-product ratio produces significantly less wastewater per gallon than the 75 GPD or 100 GPD models.
- Dow Filmtec TW30-1812-100HP membrane provides 96 to 98% typical salt rejection at 65 PSI.
- Refillable DI cartridge with color-changing resin for visual exhaustion monitoring.
- Auto shut-off valve and manual flush flow restrictor included.
- No power source required; runs on 65 to 80 PSI household water pressure.
- Same footprint and dimensions as the 150 GPD at 16" x 6.5" x 18".
- Standard 10" canisters and 1/4" push-connect fittings.
- Glycerin-filled pressure gauge included.
Ideal For:
- Large reef and saltwater systems where daily top-off or frequent large water changes require the highest available purified water output.
- Fish rooms, coral propagation setups, or multi-tank systems where production volume is the primary concern.
- Hobbyists on metered water or in drought-restricted areas who also need maximum output and want the best waste ratio available in the line.
- Installations where supply pressure is reliably 65 to 80 PSI or where a booster pump is already in use.
