Envig Torrent 3200 GPD Portable RODI/RO Water Purification System

The Envig Torrent 3200 is a portable, wheel cart-mounted RODI/RO system built to deliver spot-free, zero-TDS water on demand — wherever the job is. At up to 2.2 GPM and 2:1 pure to waste ratio, it delivers top-notch performance, while staying rollable and one-person portable. What sets it apart is visibility and control: three separate TDS readings (tap, post-RO, post-DI) let you see exactly how each stage is performing and when to service, and a single four-position all electronic dial replaces the cluster of separate manual valves. It has digital flow meter and resettable gallon count so you can track output for jobs.

Key Highlights

Up to 2.2 GPM pure-water output — Enough flow for mobile detailing rinses, water-fed pole window and solar work, hydroponic reservoir fills, or whole-house reverse osmosis needs. Competitive with dual-RO while remaining single-cart portable.

Three independent TDS readouts (Tap · RO · DI) — Most carts give you one inline meter, if any. The Torrent shows tap input, post-RO, and post-DI separately, so you know the rejection rate of the membrane and the polish of the resin at a glance — and you know precisely which stage to service when numbers drift, instead of guessing.

Efficient 2:1 pure-to-waste ratio — Produces more usable water per gallon of feed, reducing wastewater and feed consumption on the job.

Single four-position control dial (Bypass · Off · Pure · Flush) — Everything lives on one switch. No hunting across separate bypass and flush valves the way you do on many other systems.

Tap-water bypass through the same Pure outlet — Flip to Bypass and draw regular tap water from the very same outlet — no swapping hoses or fittings when you don't need purified water.

One-touch membrane flush — A dedicated Flush position lets you rinse the membrane after each session in seconds, clearing concentrated solids and extending membrane life — the single biggest factor in long-term cost per gallon.

Flow rate + gallon counter with resettable cycle — Live GPM plus an all-time total, with a resettable cycle counter so you can track output per job, per tank fill, or per filter interval. Far beyond the manual pressure gauge most carts ship with.

Envig K3 filter as prefilter with signature catalytic carbon — Standard carbon blocks remove chlorine but struggle with chloramine, which is far more aggressive toward RO membranes. The K3's catalytic carbon is engineered for maximum chloramine removal, protecting the membrane from the contaminant most likely to degrade it — directly extending membrane life and sustaining rated production over time.

Standard 10×4.5" refillable DI canister — Refill with loose resin instead of buying proprietary cartridges, cutting waste and operating cost. Don't need DI for a given job? Swap the canister for a different post-polish filter, or run RO-only and save your resin.

Pre-membrane pressure gauge — Monitor feed pressure at a glance to confirm the membrane is getting what it needs for full rejection and rated flow.

Portable cart format — Wheeled, handled, and powder-coated for the field; rolls between driveways, job sites, greenhouse rows, or a utility hookup and use handle to move up and down a vehicle.
